Ultraviolet & Tank Sanitation
Ultraviolet Water Sanitation is by FAR the most important filtration process when it comes to rain water filtration. Rain water harbours bacteria of all types, but is some cases much more harmful bacteria may be present in the tank. E-Coli is a common bacteria in tank water and is due mostly to Frogs in and around your tanks/catchment. Ultraviolet sanitation works by breaking down the cell wall of a micro-organism allowing oxidation to occur which in turn prevents the bacteria from multiplying until it is finally eradicated.
Ultraviolet filtration is a chemical free solution to water sanitation creating no by products in the water.
For instances where UV sanitation is not viable, Products such as HydroSil-ULTRA (Silver Hydrogen Peroxide) can be used to kill bacteria and viruses, while leaving no residuals in the water and is perfectly safe for drinking water.
