Ultraviolet (UV) Water Purifier

2009-11-10T06:12:00.000-08:00

Ultraviolet (UV) Water Purifier is products of a complex science. UV light is a wavelength of light which is exists between the light that is visible and the x-rays on the electromagnetic spectrum. There are three subcategories of UV, which are UV-A, UV-B, and UV-C. UV-A and UV-B are the UV light that are responsible for people’s suntan or any sunburn. UV-C light is a much more damaging form of UV light and has a much higher energy. The UV-C is the light that is being used in the Ultraviolet (UV) water purifier systems.

UV-C light is a very damaging and very powerful form of UV light. The UV-C light is able to penetrate through living cell and would be able to damage the organism DNA. DNA (deoxyribonucleic acid) responsibility is to direct the activities in a living cell. All living cell to function properly need DNA. UV-C light with the ability to penetrate through the living cell and attack the DNA stops the replication of the DNA. This actually preventing the living cell from reproducing and causing bacterial or viral cell cannot reproduce and the bacterial or viral cells will not be able to cause infection.

The process of ultraviolet water purifier is to expose ultraviolet light and to make the microorganisms not able to reproduce and rendering them harmlessly to anybody that drinks the water.

There are two types of UV water purifiers that are available in the market. Point of entry, which could be installed on the main water line to purify all the water passing through and point of use, which the would purify water at a single faucet.

UV water purifier will not turn muddy water to clear, it will not eliminate chemicals and it will not change the taste or smell of the water. For these reason it is often necessary to install a water filter before the UV water purifier to purify the water.

Portable UV water purifier may be taken for camping or hiking. Some of the UV water purifier can run off of batteries or solar power. These types of UV water purifier would be very effective for traveling.

UV water purifier manufactures are producing different sizes of UV water purifier’s models. A longer UV lamp would be required for higher water flow rates and a shorter UV lamp is usable for slower flow rates since the water that is treated would resides for a longer period in the UV system.

Portable Water Purifier

Portable water purifier is a device meant for people who must obtain drinking water from untreated sources such as rivers and lakes. There are many portable water purifier available for camping, hiking, and other travel in remote areas. Portable water purifier can be used to remove bad taste, chlorine, odors and other substances like mercury and lead.

Portable pump filters as water purifier are available with ceramic filters to remove pathogens. Some portable pump filters also using activated charcoal filters. These filters with activated charcoal will be able to remove most bacteria and protozoa, but it will not be able to kill viruses with less than 0.3 micrometer diameters. To complete the process of water purification, disinfection by chemicals or ultraviolet lights is required. On the market there are polymer and ceramic filters that incorporated iodine post-treatment to kill viruses and bacteria that cannot be filtered out, but these filters are not advisable due to the possible adverse health effects.

Even though the filter can do great job on removing bacteria and fungi from the drinking water when it is new, but used filters eventually can be colonized by the bacteria and fungi. Silver metal nanoparticles can be bond to the ceramic element and the activated charcoal to suppress the pathogens growth.

Water Purifier: Reverse Osmosis

2009-10-10T23:19:00.000-07:00

Reverse osmosis is a process involving a diffusion mechanism and it is working by the use of pressure forcing a solution through a membrane, to retain the solute on a side and to allow the pure solvent passing to the other side. There is a dependency on pressure, influent solute concentration and water flux rate to determine the efficiency of the separation of the diffusive mechanism. This method is reversing normal osmosis process which why it is called a reverse osmosis.

Membranes that is being used for reverse osmosis is having a layer which is dense enough in the polymer matrix where the most separation of the diffusive mechanism occurs. The membrane is being design only to allow water to be able to pass through the dense barrier layer in the polymer matrix and to prevent solutes passing through. The reverse osmosis process needs a high concentration side of the membrane to exerted by a high pressure, for brackish and fresh water 2-17 bar usually sufficient enough, but for seawater the pressure would need 40-70 bar, which natural osmotic pressure must be overcome that is around 24 bar.

The process to get fresh water by removing salt from sea water is called desalination. It is one of the processes of water purifier. Desalination also has been used for medical, domestic and industrial applications for water purification.

Water purifier systems which households around the world are using for drinking includes a reverse osmosis method. The reverse osmosis method is used to improve the quality of water to drink and cook.

Water purifier systems for drinking and cooking are typically using sediment to filter particles including calcium carbonate and rust then the water has to go through an optional second sediment filter with smaller pores for better filtration. To trap chlorine and organic chemicals, water purifier is using an activated carbon filter. A second carbon filter optionally is used to capture the chemicals which could not be removed by a thin film composite membrane, a reverse osmosis filter. The chlorine and organic chemicals which is trapped by the activated carbon filter has the ability to degrade the thin film composite membranes which is known as TFC or TFM. Then any escaping microbes from the reverse osmosis membrane filtering are going to be disinfected by a ultra-violet lamp.

Reverse osmosis for home water purifier has disadvantages, as because household have low back pressure it uses a lot of water. The result of the low back pressure, the water purifier which is using reverse osmosis method only recovers 5% to 15% of the water that enters the water purifier system. The remaining water, 85% to 95% is considered as waste water and is being discharged. Methods to recover the waste water are not considered for household systems as the waste water carries the rejected contaminants. Water purifier using reverse osmosis method is more suitable for large scale industrial system as the large scale industrial system can generate high pressure which is essential for reverse osmosis filtration and can give efficiency in the production. Mineral from boiler water at power plants can be removed by using reverse osmosis method. Reverse osmosis method is more suitable for industrial sector.

Water Purifier: Methods

2009-10-06T00:56:00.000-07:00

Water purifier is a tool to battle against many dangerous substances in our water source like our tap water and well. These dangerous substances are including bacteria, heavy metals, and toxic chemicals. Being exposed to these dangerous substances can have bad effects and very serious in long term health conditions. Water purifier methods which are the most popular nowadays are reverse osmosis and carbon filtering.

The water purification methods that are still popular today are boiling water, chemicals usage, carbon filters, and reverse osmosis.

Boiling water and using chemicals for water treatments are consider traditional methods to purify water. These traditional methods are able to remove some water contaminants but the methods are still able to leave unhealthy substance since there is no filtration system to filter the water.

Boiling method needs to have the water heated long enough and hot enough to eliminate the microorganisms. At a near sea level, water needs to be boiled at least one minute. At higher places, three minutes of boiling is much recommended. Boiling water remains effective to eliminate protozoa and bacteria but there are still other microorganisms that could survive the boiling process. Boiling is considered a non efficient method of filtration and could not remove dangerous chemicals, if there's any, like chlorine. Boiled water should not be stored for long time as it may acquire other pathogens due to the effects of boiling. Water that is boiled does not have any residual disinfectant left.

Chemicals such as iodine and chlorine are the chemicals that are being used in water purification. Iodine and chlorine are cheap and easy to use. The use of chlorine can kill viruses, bacteria and protozoa but it could also leaves a bad taste and not recommended for water purification in long term. While chlorine can make the water looks clearer, it is poisonous and can create serious side effects for health if it is being used too much.

The traditional water treatment methods are proved to be ineffective and considered dangerous for health. There are new water purifier systems to deliver clean water without side effects. Methods which are popular nowadays are carbon filters, distillation and reverse osmosis. These are considered new methods of water purifier.

Carbon filters is using filter cartridges that is made from carbon for absorbing contaminants, including many toxic compounds like chlorine and microorganisms. In regions with many organic contamination, taste or smells, activated carbon is used as filter, passing through water. There are several ways to use carbon filters, mounting it to faucets or to integrate it with refrigerators are some of the ways. Carbon filters will not be leaving bad tastes and often being used with reverse osmosis in home water purifier.

Distillation is a process of producing water vapor by boiling the water. The water vapor will then be condensed as liquid after contacting a cool surface. Distillation could achieve 99.9% of pure water.

Reverse osmosis very effective to filter water impurities, including dissolved solids, nitrates, lead, turbidity, asbestos, radium and organic matter. It can even eliminate radioactive substances and chlorine. Reverse osmosis process works by giving pressure to a solution and to squeeze it through a membrane, leaving the contaminants trapped.

The History of Water Purifier

2009-10-03T02:23:00.001-07:00

Water purifier history is actually tied to water history. Human civilizations always thrived and flourished near water source. Water has always been important and necessary for human to survive as water was used for drinking and also for the operational of agriculture. In history, human were much more concerned about the quantity of the water rather than the quality. They emphasized more on to the aesthetic problems of water such as the taste, smells, and appearance. Human slowly realized that its important to drink pure water and the journey to get pure water was started. Driven by the quest for pure drinking water, water purifier was invented after thousand of year’s journey.

The Egyptian and Sanskrit, ancient language writings, reveals that people during that time was keeping the water pure and free of germ. There is a Sanskrit ancient text mention of keeping clean water. The methods include boiling the water, heat it under the sun, or to dip a heated iron into water. The ancient text also mentions the water purification process, water filtration through sand and coarse gravel then to allow it to cool. Charcoal filtration method is also stated in other ancient Sanskrit text. Water treatment device also were painted in an Egyptian tomb, proving its existence since thousands of years ago.

Water Purifier also was mentioned by Hippocrates, the father of medicine. Hippocrates invented water purifier and it was called "Hippocrate's sleeve". Hippocrate's sleeve was a cloth bag and it was used as a water purifier to help removed hard substance and bad odor from the water.

Various methods were also developed by the Romans and Greek to treat water in such a way so they could control the taste of the water and smells.

According to Sir Francis Bacon if seawater is allowed to percolate through the sand, it can be purified. It was the method of desalination. Sand filtration experiment was being illustrated for the first time by an Italian physician, Lucas Antonius Portius. Written elaborately by Lucas Antonius Portius on his book "Soldier's Vade Mecum", the method of multiple sand filtration. The water filtration experiment was illustrated by making used of three pairs of sand filters.

Water Purifier that many people use now is using sand filtration method. In the 18th century, a Scientist in France, La Hire, proposed that every household should have a sand filter and a rainwater cistern to help the keep fresh pure water.

In the 19th century, Scotland, the first municipal water treatment plant was installed which consisted of sand and gravel filters. A similar pattern of the municipal water treatment then was installed in London. The sand filtration method had gone to further progress when the rapid sand filtration was developed later on in the United States of America in the late 1800. Water jets of back washes were being used to clean the filter media in the unit and to loosen the debris, a mechanical agitator were used. The water treatment capacity was enhanced, the smells and taste of water was also improved by using charcoal filtration for the water purifier.

The water cleanliness and the relation of it with health in the 19th century were being understood. Many other techniques of water purification by disinfecting water such as chlorination were also developed since then. Many more progress in water treatment was made after the industrial revolution of water purifier.
