Activated Alumina Defluoridation Filter - These filters are used in locales where fluorosis is prevalent. They are relatively expensive and require frequent replacement, but do offer an option for home water filtration.
The filter is especially useful when the water is rich in sediments, suspended particles, iron and certain microorganisms causing water borne diseases. Turbidity up to 500 NTU and Iron up to 15 ppm can be easily treated with this Terafil filter. It is suitable for both surface water source like river & ground water sources like dug wells, ponds, tube wells. The filter consists of a Terafil disc which is a porous sintered red clay disc and treats the raw water through filtration. It not only removes turbid particles, microorganisms, iron, color & bad odor from raw water, but also improves the taste. The rate of filtration can be increased many folds by applying pressure.
A water filter makes mountain stream water safe to drink when you're backpacking in the wilderness. these filters are particuularly effective at removing pollutants which create unpleasant taste, colour, and odour in water. These fast-acting filters can eliminate or reduce the levels of chlorine by-products, pesticides, herbicides, and other organic and industrial chemicals.
