The Viqua VH410 is a powerful UV water purifier that can be used on water flow rates of up to 18 GPM. With a high UV output, this UV water filter is smaller in size, helping you to save space while providing an equal performance to a larger chamber. Price: $786. UV Dose Delivery: 40 mJ/cm². Some filter designs are more suitable for removal of Cryptosporidium than others. Filters that have the words “reverse osmosis” on the label protect against Cryptosporidium. Some other types of filters that function by micro-straining also work. Look for a filter that has a pore size of 1 micron or less. Yep, absolutely. Most UV installs also require a 5 mic pre filter and carbon does a nice job of polishing off treated (if it needs it) water. We’ve drilled wells where I’ve had to put in anything from just a sand filter all the way to double pump de-gassing systems and chemical injection iron filtration, all within 30km of our shop. The UV dosage required is the intensity of UV light that can penetrate each liter of water measured in millijoules per liter (or mJ/cm2) that passes through the UV chamber. The UVT of your water supply determines the dosage required for proper disinfection. 16 mJ/cm2 - This is standard UV disinfection. This filter can treat water by using a UV lamp powered by electricity. The water is sterilized with a special type of UV radiation used, UV-C light. The UV-C light has a specific radiation wavelength measured at 254 nanometers (nm) that allows it to perform its primary function, kill germs. UV Light Water Filters Kill Germs The Yarna UV filter, on the other hand, is shaped in such a way that it exposes water to the UV-C rays for a prolonged period of time, thus increasing the number of microorganisms that it can eliminate. This is because we have made a spiral pipe through which the water flows. The spiral pipe surrounds the UV-C lamp with a quartz tube, so the Also, germicidal ultraviolet does not have a residual effect; therefore, it is beneficial to put the water purifier as close as possible to the point of use. Installing the filter prior to the ultraviolet water purifier reduces the possibility of re-contamination of the water in the filter. Selecting the Correct UV Dose for Your System. The amount of UV energy from the lamp to the water as it flows through the system is the “UV dose” expressed as millijoule per square centimeter or mJ/cm2. E. Coli, Giardia, and Cryptosporidium typically require a UV dose of at least 10 mJ/cm2 to become inactivated. .
