It produce high quality water without the use of chemical aids. Passing flocculated water through a gravity sand filter strains out the floc and the particles trapped within it reducing numbers of bacteria and removing most of the solids.
Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption.
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.
Nanofiltration (NF) is a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter.
Iron removal systems use all Natural processes to remove iron from well water and also remove manganese, hydrogen sulfide odors, and raise pH.
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. Water softening is usually achieved using lime softening or ion-exchange resins.
