Recent advances into the design & configuration of small scale Ultra Filtration ("UF") as well as ultraviolet sterilizer ("UV") systems has allowed this technology to be available to kill bacteria in residential well water systems. The combining of ultra-filtration with UV sterilizers means that now home owners can have access to disinfected drinking water free of bacteria at affordable prices.
The United States Environmental Protection Agency regulates municipal water utilities however it doesn't have the legal right to regulate non-public drinking wells. Approximately 15 % of persons in the U.S. depend on private well water supplies, and these supplies usually aren't governed by EPA regulations. In contrast to public water utilities serving many people, households that get drinking water from privately owned bore holes do not have professionals routinely examining the water source and its quality before it is delivered to the faucet. These households need to take special precautions to ensure the water is safe.
Inadequately treated water may be contaminated with microorganisms that cause disease, often referred to as pathogens. Pathogens include various types of bacteria, viruses, protozoan parasites, and other organisms. For public water supplies chlorination is among the most common procedure employed to destroy microorganisms. For privately owned wells, many homeowners rely on Ultra violet sterilizers to make certain the water is safe from harmful bacteria. A type of water purifier known as UF can be used to deliver superior sterilization of the water without the costs & upkeep involving chlorination or UV.
UV sterilizers employ ultra-violet light to kill bacteria as the water flows within the UV system. The bacteria are radiated with powerful UV rays & thereafter are not able to replicate. In contrast to chlorine, there are no chemical like by-products or tastes using UV sterilization. Even though UV will do a good job at killing harmful microorganisms, in the event the UV system is improperly sized, or if the water being treated consists of excessive levels of metals or perhaps color in it, some of the bacteria might not be completely killed, and thereafter can redevelop inside the home plumbing and fixtures. Ultraviolet will not actually take out bacteria from the water and in some cases the bacteria might only end up being partially damaged, particularly if the well water is not sufficiently low enough in minerals or clear enough to allow UV light to successfully penetrate the water. UF membranes by contrast filter a water right down to sub-micron levels and effectively remove all microorganisms, sediment and turbidity.
Savvy consumers occasionally inquire about the difference between UF and UV systems for disinfection of well and spring waters. The main distinction is the fact that UV kills bacteria but doesn't remove them, while UF is able to physically block them. Whereas Ultraviolet relies upon electrical energy to function, UF doesn't need electrical energy. In the event of a storm or flood, boil-order, or other unexpected emergency a UF will continue to take out bacteria, while an Ultra violet sterilizer will not.
Hollow-fiber UF membranes are used all over the world to treat municipal and industrial water on a large scale. Recent advances in small-scale membrane chemistry and design have made UF membranes resist breakage, and can be easily cleaned. Small package systems that include automatic backwash controllers mean that now UF systems are practical for home well water applications.
UF filters look like strands of noodles and have hollow cores. The membrane surface is a physical barrier to bacteria. The use of hundreds of these fibers incorporated within each device provides adequate surface area to supply flow rates of 10 gallons per minute for each standard size 4 x 40 " UF membrane. UF hollow-fiber membrane strands contain millions of 0.015 micron (nominal) sized pores. For example, the Cryptosporidium and Giardia cysts, two widespread types of parasitic organisms are approximately 7 to 10 microns long and are oblong in shape. UF systems have been independently certified and tested to block 99.99.999 percent of bacteria and 99.999 percent of viruses.
UF membranes are well-suited for disinfection of bacteria and turbidity removal because their arrangement provides for effective backwashing and rinsing. These newer kinds of home UF systems have automatic backwash control panels which permit the units to work well with either municipal, well water, rainwater or surface water. For water that is very infected with pathogenic agents a combination of UF followed by UV is an excellent pairing. The UF system removes turbidity and color, and acts as a physical barrier to micro-organisms and is installed in front of the UV. The ultraviolet sterilizer then serves as a back-up barrier to make sure the water is free of bacteria and viruses.
