Carbon filtering is a method of water purification that uses a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media. Puri Centric carbon filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. Coal, coconut shell and palm shell based activated carbon with variety sizes are available to choose for different applications.
DMI-65 is the most advanced catalytic water filtration media that we used in our ion removal filtration system which has extremely high capabilities of removing both Iron (Fe) and Manganese (Mn) simultaneously through low cost catalytic oxidation and retention of precipitate. The DMI-65 will also remove arsenic from a water supply given the correct conditions. DMI-65 has been shown to remove arsenic associated with iron-containing influent. Ferric chloride is used when treating feed waters with high arsenic feed levels.
Sand -Glass Filtration
Impurities are removed from water by passing through a bed of quartzite sand or glass of various gradation. The installation of a Sand/glass filter is recommended when the load of turbidity (sand, lime, scales, colloids, etc.) of water is very high, affecting the water quality and resulting in deposits and encrustations on pipelines, boilers, taps and on domestic and industrial appliances in general. All media included in our filters are carefully selected according to particle size, so the media retains its stratification during backwash and rinse.
Water softener reduces the calcium or magnesium ion concentration in hard water. These “hardness ions” cause two major kinds of problems. The metal ions react with soaps and calcium sensitive detergents, hindering their ability to lather properly and forming an unsightly precipitate. Presence of “hardness ions” also inhibits the cleaning effect of detergent formulations.
