Ultraviolet Water Treatment Systems

The Ultra-violet lamps of a water treatment by UV produce UV-C. No UV-C rays from the sun ever come into contact with life on earth, they are completely filtered by the atmosphere. However, man produced UV-C rays do. The UV-C lamps are used in biology laboratory for the effects of germicides. Those UV-C have a radiation with an intensity far greater than the sunlight and are used in the treatment of water to sterilize it.

The UV filter can kill most bacteria and viruses in water. However, this type of water treatment does not completely purify water. Indeed, it does not treat the water against chemical pollutants, for example. The installation of systems ultra-violet water purification are therefore combined with other system of water purification, UV light generally has no impact on chlorine, heavy metals and other chemical contaminants.

How UV water treatment system works?

The water purification by ultra-violet uses a UV light source (lamp), which is enclosed in a transparent protective sleeve (usually quartz). The lamp is mounted in such a way that water passes through the filter by a room flow. The water is then exposed to UV-C rays. When harmful microbes are exposed to UV rays, their nucleic acid absorbs UV energy, which blurs the structure of DNA. The cell is rendered sterile and can no longer reproduce. The cell is now considered dead and no longer a threat.

Why use an ultra-violet water purification system?

UV water purification technology is probably the most cost-effective and most efficient on the market today. It allows homeowners and business owners to remove a range of biological contaminants in their water supply. The UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants. Most importantly, it leaves no chemical in water, it produces no by-product, and it does not change the taste, pH, or other properties of water. Consequently, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system.

The UV treatment is an excellent choice for eliminating biological contamination of most waters. If your home or business requires an additional filtration or if you have a source of private untreated water (rainwater, lake water, wells etc.). The unique objective of UV water treatment system is to kill harmful biological contaminants.

Filtering Your Well Water

Approximately 15% of homeowners in this country are not hooked up to a public water supply and must employ the use of a private well. Unlike a city or municipality water supply, household wells are not subject to the rigorous EPA testing and standards. Well water can contain a high amount of naturally occurring minerals such as magnesium, iron and calcium, as well as harmful bacteria. If your well water has a cloudy appearance, it could mean an abundance of sediment has entered your water supply.

Excessive magnesium or calcium can form a scummy buildup and leave everything the water touches with a slimy feeling. Green stains on faucets and metallic fixtures indicate high acidity, while brown or red stains are the telltale sign of a high dissolved iron content. If you notice your well water tastes salty, it could mean that excess minerals have entered the water supply, giving the water a high sodium content. If your water tastes soapy, it is most likely due to the dissolved alkaline minerals. A metallic taste means your water has a either a high acidity or high iron content, while a chemical taste could indicate that your water has been contaminated with pesticides or other chemicals.

Sometimes, well water can have an unpleasant odor to it, causing you to realize something is wrong before you can see or taste the problem. If the water has a musty or earthy odor, it could mean that organic material is decaying and entering the supply. A rotten egg smell is indicative of hydrogen sulfide gas. A soapy smell may mean that chemicals in your septic tank are leaking and contaminating the well water. You can clearly see why it is a necessity to make sure you have a water filtration system in place if your household uses well water. These filtration systems can remove all harmful minerals, bacteria and chemicals before the water reaches the tap.

It is important that a water filter systems remove all harmful contaminates while leaving the minerals essential to human health in the supply. Well water filtration systems must be able to remove organic and inorganic bacteria and contaminates that cause unpleasant odor. These systems can remove hydrogen sulfide, iron, chlorine, and other heavy metals and bacteria. Home based water filtration and purification systems come in a variety of styles. Some are under the sink units, which filter the water before it reaches the tap, while faucet-based units can purify the water as it is coming out of the tap.

For household well water, it is recommended to have a water treatment system in place before the water reaches the house. This ensures your water is safe as it travels through the plumbing and doesn't sedimentary build-up on the pipes. If you use a well for your household water, make sure you have a filtration system in place. It will ensure your health and safety, as well as improve the taste and smell of your water.

The Merits of Water Purification

When it comes the time to decide on a water purification system for your home, it would be alright to choose any water purifier rather than not choosing any at all. Of course, there are some differences among water purifiers. Some water purifiers are more efficient or work better than others. Sometimes the difference in price does not translate into a difference in quality. We have included here some important information that can help you when shopping around for the appropriate water system for your home.

When selecting the proper water purification systems, health and safety should be non negotiable essential elements to be taken into consideration. It is helpful to know that primarily public treatment installations try to protect our health through disinfection. Depending on the steps used by the public treatment facilities to disinfect the water, you may end up using more than one water purifier depending on the source of your water.

If you do not have a water treatment facility in your area, then you should seriously consider the source of your water before you decide on a water purifier. There are usually a number of pollutants in water that need to be dealt with and consequently there are various steps that need to be taken to accomplish that purpose. Public treatment facilities use various steps to disinfect the water and you may end up using more than one water purifier depending on the source of your water.

For instance, in the rare occasion that your water is obtained from a river or lake you need a thorough lake or river-water purification. In that case, the total process may include the following water purification systems: reverse osmosis, selective distillation and filtration. This is so because each water purification system focuses on specific contaminants and fails to eliminate others. Just look at the following analysis:

Water purifiers that use distillation are needed to kill bacteria, but if you boil the water you can get the same effective results. When your water comes from a treatment facility, disinfection has already been done, and usually E. coli and other bacteria are not present, except in the case of a massive storm or similar event. But bacteria might still be present in the spore step of evolvement. Reverse osmosis water purifiers do not remove herbicides, pesticides, VOCs, THMs or bacterial contaminants. You are more likely not to use this purifier since your water source might not be a lake or river, and consequently you can skip this step in the process. This step is completed at the public's water purification program if your water comes from that source.

Under the Sink Water Filtration Systems

An effective way to ensure that your family is receiving filtered, purified water directly from the tap is by installing an under the sink filtration system. These systems are similar to countertop or faucet filters, but is located under the sink and directly married with your existing plumbing system. An under the sink filtration system can provide clean water straight from the tap, all while reducing countertop or sink clutter.

You can install a under sink filtration system anywhere in your home that has running water. While your kitchen is probably the number one area for receiving drinking water, take into account that you also ingest water from the bathroom. Even if you use your bathroom sink just for brushing your teeth, you still are ingesting water into your body. To reduce your intake of harmful chemicals and minerals, install an under the sink filtration system here as well.

While some water filtration systems can clean and purify the water before it even enters your home, a under the sink system will also remove any contaminates incorporated into the water from your pipes. Your pipes may contain chemicals such as vinyl chloride. An under the sink water filter systems will remove any contaminates picked up from your household plumbing as well as water-borne contaminates from before the water reached your house.

An important benefit of using a water filtration system that is located under the sink is that it is hidden from view and out of the way. Faucet filters and countertop filtration units are bulky and can take up much-needed and limited space. Filtration systems that are installed under the sink are in cabinet or some kind of enclosed space, thereby allowing them to be larger and be able to handle the filtration of more water much quicker than the smaller faucet-based or countertop units.

When deciding on what type of filtration system is right for you and your family, consider that some minerals that are necessary to human health are naturally found in our drinking water. Choose a system that will remove the harmful chemicals and toxins from the water, while keeping the essential minerals that are beneficial to your well-being. Some mineral content is always better than no mineral content to protect against mineral deficiencies and keep you healthy.

Buying Guide for Water Purifiers

In the above given lines the poet is referring to a situation, despite having so much water around you cannot drink the water because it is contaminated and unhealthy. Tap water may contain many biological and chemical contaminants, it may contain many bacteria or viruses which can lead to serious body infections. Clean and clear looking water can also give you water-borne diseases.

Boiling, one of the oldest methods of water purification kills most micro organisms. Many households in India still use the candle water filters. But with the fast moving lives nobody has got the time to purify water manually. And above all, mechanized water purification systems are considered to be more reliable. So your safety is in your own hands and it becomes your foremost duty to buy a water purifier for your family’s safety. But choosing a water purifier can a tricky thing, let me help you out.

Types Of Water Purifiers

Storage Type

In the storage type water purifiers a large quantity of water is stored at a time and used later when required. This type of storage is very helpful in places facing water shortage.

Direct Flow Type

This type of water purifier can be used at a place where there’s whole day water supply and very common in households. In this type of water purifier, the purifier is directly connected to the tap and you are saved from the hassles of water storage.

Features Flow Rate

When purchasing a water purifier, always look out for flow rate. The flow rate should not be much as it will easily allow bacteria to pass through the system. The most suitable filter is that in which the water flowing capacity is a liter per minute.

Body

The body of a water purifier should be light-weighted, rust-proof, durable and attractive. Water purifiers are available in various materials.

Purification Method

There are different stages of water purification used by Water Purifiers, some have three and some have five water purifying stages. Higher number of purification levels ensures cleaner water.

Few stages of water purification are:

Pre Filter Purification - A micron pre-filter is to remove silt, dust particles from the water before it enters the main filter of purification unit.

Candle Filter Purification - The micro porous candle filter removes all suspended impurities.

Health and Taste Cartridge - The health cartridge helps in disinfecting the water from bacterial and virus infections. The taste cartridge absorbs elements such as excess chlorine and impurities like pesticides, herbicides from water making it hygienically clean.

Reverse Osmosis Technology - Reverse osmosis separation technology removes dissolved impurities from water. The Reverse osmosis systems removes impurities as well as desalinizes the water. RO is must in places where there is hard water supply.

Ultrafiltration and Nanofiltration - These processes removes dissolved solids ranging from the size 0.005-0.1 microns and 0.0009-0.007 microns. They are capable of removing solids, bacteria and viruses. They are mainly used in large water plants or liquid treatment plants. It’s rarely found in domestic water purification.

Water Treatment Plants

Water treatment plants treat water from various sources like rivers and lakes. Water from these sources has to be purified to remove floating objects like sticks and other solids of larger dimensions, finer particulate matters, color, odor, pollutants, and harmful bacteria and microbes.

The water entering the treatment plant passes through intake screens to remove floating objects and larger insoluble materials. Back-flushing of the screen with air is done periodically to clear the screen and maintain the effectiveness of the screen.

Coagulants are added to the water to facilitate the subsequent sedimentation process. Water containing the rest of the impurities is taken to a sedimentation tank containing sand filters to remove suspended solids. Sand is then recovered and cleaned so that it can be reused. The next process is the bacterial disinfection and degradation of the organic compounds by treatment with ozone gas. Ozone, being unstable, is produced onsite by the use of oxygen in an electric discharge unit. The ozone thus produced is bubbled through water. Residual ozone is then converted to oxygen gas and vented out to the atmosphere.

Water will still contain some turbidity and other organics. An activated carbon filter is used to remove these impurities along with any remaining colored materials and odor-causing chemicals. Final polishing of this water is carried out by sand filters, and this water is taken to storage vessels. A small amount of chlorine can be used to treat this water to prevent bacterial contamination before the supply to the distribution system.

Thus, water from natural sources can be fully purified and disinfected and then stored in underground storage tanks.

Are Water Purification Products Necessary?

Water purification systems for homes are needed because on too many occasions' today people turn on their water faucets only to be hit with discolored water, ghastly smells, and terrible tasting water. This occurs even though the public water authority says the water is perfectly safe to drink. Water purification products are popular due to these reasons.

Of course, they are testing the water when it leaves their water purification plant. However, most of the water delivery infrastructure has been in the ground for decades and even longer in some cases. Allowing the buildup of sediment and other contaminants the water must pass through to arrive in homes.

For the reasons listed above the home water purification systems for homes and water purification products have become very popular today. They are also used to remove chemicals and minerals from water that many people do not want to drink. Some of these include chlorine, fluoride, calcium, and magnesium.

The desire to drink pure water from water purification products has given rise to the bottled water industry. Although the water has been filtered and cleaned, the long-term result is an additional cost for water. The use of bottled water, coupled with paying for water delivery to a home results in a long-term expense that can be eliminated by installing water purification systems for the home.

Water purification systems for homes come in a variety of styles and types. They range from whole house purification systems to portable and targeted water purification systems. Examples of water purification products include:

  • RHINO® EQ-300 Whole House Water Filter - handles 300,000 gallons before filter replacement; removes particles greater than 5 microns and chlorine.
  • Wellness MG Home - handles 400,000 gallons before filter replacement; removes particles greater than 5 microns and chlorine.
  • Kinetico System - handles 225,000 gallons before filter replacement; removes particles greater than 10 microns and chlorine.

Drinking water only water purification systems for homes include:

  • Brita Pitcher - handles 30 gallons between filter replacement, removes chlorine and lead.
  • Brita Faucet Filter - handles 100 gallons between filter replacements; removes chlorine, cysts, lead, benzene, atrazine, and more.
  • Aquasana Faucet Filter - handles 500 gallons between filter replacements; removes chlorine, cysts, benzene, atrazine, lead, THM, VOC, and many more.
  • Culligan Faucet Filter - handles 500 gallons between filter replacements; removes chlorine, cysts, benzene, atrazine, lead, THM, VOC, and many more.

Shower water purification systems for homes include:

How Does the Water Purification Process Work?

I don’t know a thing about you, but I’ll bet that if I asked you to explain water purification systems that you might find it really difficult.

The water purification process uses a wide variety of processes and yet it’s relatively straightforward. But the world is growing and humans are developing at a rate much faster than anyone can even imagine. The water purification process and the various technologies that have been developed in the course of time are today helping our society in a big way.

Importance of water

Water is amongst the five elements of life and needs to be consumed in its purest form only with salts that are needed by our body.

Longevity and our health are the two main aspects that are regulated by the purity of water. This makes a big contribution to the overall well-being of a person.

The health benefits of drinking pure water need to be understood by each individual and the day everybody becomes aware, most of the water-borne diseases may just disappear. The most active civilizations have prospered at locations where the water was in the most pure forms.

Our body is made up of about 70% water. Almost all the factors and processes in our body bear a close connection with water.

But drinking is not the only time when we come in contact with water. Even while bathing, washing or cooking, you interact with water and these things all affect our overall health. Water is a building block of life and so its purity is something that needs to be ensured in all senses.

How the water purification process works

It would be much easier to understand the details of various water purification techniques if we get to know a bit about it. Today, there are many techniques that are available in the market which can be used for water purification.

To explain water purification to yourself, you need to have an idea about the overall procedure first. It is impossible for only one method to clean water in a cent percent manner.

Each level of water purification has a different function. The design of a water purification process needs to be such that it uses the least number of resources and provides the maximum output. The final quality of water is the main concern of every water systems.

The sequence of a water purification process should be logically thought out. It normally adopts a step by step method in which the first step includes the elimination of particulate matter. The next step should be of disinfecting the water so that the microbial germs in the water die. The third step reduces the hardness of the water.

The various methods of water purification have been the subject of much research and discussion. Their conclusions can help you and I as individuals to decide which method to go with.

It is important to understand that a system needs to compatible with the surroundings and should not be complicated to use. Now that you’re armed with this information, you can choose the water purification process that is most appropriate for your family.

World Water Desalination

World Water Desalination to 2013

Continued rapid growth anticipated through 2013

The very word “desalination” usually triggers thoughts of oil-rich, water-poor countries in the Middle East. And while it is true that several such countries -- Saudi Arabia, the United Arab Emirates and Kuwait -- are among the largest markets for desalination, there are desalination facilities in more than 100 countries. The continued proliferation of desalination facilities has created a global market of more than $8 billion, with continued rapid growth anticipated.

Thermal processes limited to energy-rich markets

The most traditional techniques for desalination have involved thermal processes. The most common contemporary thermal processes, multi-stage flash (MSF) distillation and multiple-effect distillation (MED), are highly reliable and capable of producing remarkably pure water from the saltiest seawater sources. However, these techniques -- especially MSF -- consume large amounts of energy. These techniques tend to be economically viable only when water shortages are most severe and when local energy supplies are abundant -- such as in Saudi Arabia, the UAE, Kuwait and a few other countries in the region. Elsewhere, shortages of quality water can also be daunting. This is true in China, Spain, Australia and parts of the United States -- where populations have outgrown native water supplies or local water supplies contain so much salt and other dissolved solids that they are not fit for use. These difficulties are perhaps most severe in Middle Eastern and North African nations not endowed with plentiful oil and gas reserves but beset with similarly arid conditions and lack of indigenous water supplies.

Residential Reverse Osmosis Systems

Although their popularity has declined over the last years, residential reverse osmosis systems are still one of the alternatives that the average consumer considers when he or she becomes aware of the importance of having clean, healthy water at his or her home.

After studying the pros and cons of these residential reverse osmosis systems, I came to the conclusion that I should advise against them. Below, I will give you the three top reasons to support my decision. I rank them in terms of importance, the first being the least important.

Reason #1: They are very slow in processing water. This drawback is directly related with their principle of operation: Water has to be pushed with high pressure through a porous membrane. Whatever has smaller molecules than the pores (water) passes through the other side, while whatever has larger molecules (pollutants) stays behind. This whole process is slow because of the time it takes for water to pass these very small pores.

Typically, it takes about two to three hours for enough water to pass through the membrane to produce 1 gallon of water. Because of this, residential reverse osmosis systems use storage tanks holding 2 to 5 gallons of water. When drinking water is drawn from the RO faucet, the water comes from the storage tank.

As you realize, this fact puts some restriction on the space you want allocated at your house, as well as on the level of availability of the water you want to have, in order to cover your everyday needs.

Reason #2: To make matters worse, most RO units waste a lot of water. Just to give you an indication, they typically use between 3 to 10 gallons of tap water to produce 1 gallon of purified water; the remainder drains away.

This means that your ongoing cost per gallon of water produces goes up, due to higher consumption of tap water. Also, your installation set up should be more complicated, in order to take care of the drained water.

Reason #3: And we come to the biggest downside of all, at least in my book. Because of the way that residential reverse osmosis systems work, the minerals (calcium, potassium, magnesium etc) which are existent in tap water are discarded, because they have larger molecules than water and so do not pass the membrane.

If you have ever tasted water without minerals then you would know what I am saying. Demineralized water is flat and tasteless.

But, it is not just a matter of loss of taste. According to credible research reports, long-term consumption of demineralised water can in fact be dangerous. After a study stretching for a number of years, the World Health Organization concluded that "drinking water should contain minimum levels of certain essential minerals".
