Polyaluminium chloride how to apply to the swimming pool water treatment In the swimming pool, there are many small diameter and human body activity secretion of sweat, cosmetics, and microorganisms can cause water turbidity, only quartz sand filter or simple filtration method is difficult It is necessary to add coagulant - polyaluminum PAC, this product is dissolved with water and impurities in organic matter into large particles, and then filtered through the quartz sand, so as to achieve the purpose of purification. First, the water purification agent series: polyaluminum chloride (PAC), activated alumina, polyacrylamide (PAM), aluminum sulfate, basic aluminum chloride, ferrous sulfate, PAC ferric chloride, sodium hypochlorite, (Poly iron), sodium hydroxide. Second, the water purification activated carbon series: powdered activated carbon, activated carbon for purifying gas, coconut shell activated carbon, activated carbon shell, amorphous activated carbon, coal columnar activated carbon. Third, water purification filter series: emery, quartz sand filter, the shell filter, stone filter media, anthracite filter, oxygen scavenger sponge iron filter, magnetite filter, zeolite filter, manganese sand Filter material, volcanic rock biological filter, pebble (gravel) cushion, garnet filter, shale ceramic filter, biological ceramic, clay ceramic, rare earth porcelain sand filter, foam filter filter, coke filter , Pebbles filter. Fourth, the tower packing series: multi-faceted hollow ball, the liquid coverage ball, ladder ring, Pall ring, aeration hose, semi-soft packing, modular packing, inclined tube honeycomb packing, fiber bundle, suspended spherical packing, Filler, backwash caps, fiber ball packing, three-dimensional elastic packing, aerator and other packing products.
