1. In addition to iron and manganese filtration system: well water (ground water) iron and manganese generally bivalent state, that water main principles of the device are: After the well water by aeration, water and iron (manganese) begins to oxidize, when the water After manganese sand is filtered, and the media due to the chemical action of the filter surface iron (manganese) bacteria (mostly bacteria spores embroidery, iron Kerry's iron bacteria, single-celled bacteria and rust-colored coat iron bacteria) of biochemical effects, may begin to occur in the filter layer biochemical reactions, oxidation reactions and physical contact with interception adsorption, interaction of these processes can be greatly accelerated water iron (manganese) oxidation, curing and removed to achieve the desired . 2. quartz sand filtration system: quartz sand filter before the water purification treatment, preliminary treatment carried out in advance, in order to achieve good results when polishing treatment to improve water quality. Because tap water contains a certain amount of impurities, such as sand, rust, red worms, organics, microbiological, mechanical impurities. The presence of these impurities, seriously affecting the purified water quality and treatment effect, therefore, must be before finishing process will reduce or remove some of the impurities, which requires pretreatment. After pretreatment by quartz sand, water can turbidity, color, colloidal solids, organic matter, iron, manganese, microbes, volatile substances, dissolved gases and other impurities are removed or reduced to a certain extent. 3 Activated carbon filtration system: Activated carbon is a weak polar sorbent, with well-developed pore structure and huge surface area, in which the pores (diameter less than 40 Angstroms) formed within the surface area, accounting for 95% of the total area above, and therefore it has a high adsorption activated carbon. Water sterilization generally leads to chlorine in the water, in order to maintain the effect of killing bacteria in water pipe network is always up to the amount of chlorine in the 0.5 ~ 1mg / L, did not end in the pipe network must maintain a 0.05 ~ 0.1mg / L of chlorine. Because of the presence of residual chlorine will damage the ion exchange resin structure, its strength deteriorated, easily broken, it must remove the chlorine in tap water. Under normal circumstances can be activated carbon to adsorb residual chlorine in tap water to remove more than 98%, in addition, a large number of activated carbon surface hydroxyl and carboxyl functional groups, various properties of organic materials can be chemical adsorption, and the electrostatic force of gravity, and therefore activated carbon can remove water for harmful humic acid anion exchanger, Fuwei acid, lignin sulfonic acid and other organic matter, resulting in improved water desalination capacity. Typically capable of removing 63% -86% colloidal substances, about 50% iron, and 47% -60% of the organic matter. The lifting of the scale system: water softening equipment, water hardness name suggests reducing equipment, the main addition to remove water calcium and magnesium ions, activation of water quality, biocide, Anti-fouling. Soft water softener commonly used [1] technology, there are two, one is the removal of calcium and magnesium ions, reducing the water hardness through ion exchange resins; another nanocrystalline TAC technology, the use of high energy nanocrystals produced, the water free of calcium, magnesium, bicarbonate ions packed into nano-crystals, thereby preventing the free ions to build scale. Soft compared with tap water, there is a sharp taste and feel, soft high oxygen content, low hardness, which can effectively prevent stones, reduce heart, kidney burden, healthy.
