Give you some car information - quartz sand filter structure: the upper anthracite (activated carbon), middle layer (quartz sand, pebbles of large size quartz sand) has a supporting role: micro flocculation to remove suspended solids, water particles, colloids, algae, microbes and some colloidal substances, quartz sand filter to reduce water turbidity
Activated carbon filter activated carbon structure: the upper and lower quartz sand: adsorption of chlorine (reverse osmosis of chlorine adsorption of organic matter and poor adaptability) microorganisms of chloride ions, removal of organic matter. The activated carbon filter to reduce water chroma and remove water taste, further improve the taste function in water pretreatment system activated carbon filter adsorption, can not remove the residual chlorine level filtering to prevent secondary reverse osmosis membrane by its degradation, and the adsorption of small organic molecules over the previous level leakage of other pollutants, adsorption removal effect obviously on water odor, colloid and pigment, heavy metal ions, but also has the effect of decreasing COD. RO can further reduce the influent SDI value, SDI
Quartz sand filter which can remove colloid and large particles. When the particles flow through the filter layer multi media filter, filter of suspended solids from the sieve gap makes suspended solids easily entrapped in the surface of the filter material: import water pressure is greater than 0.07MPa. When the filter backwash should retain a certain amount of surface dirt forming membrane with the passage of time, before and after the filter pressure differential will increase rapidly until the failure. This requires the use of reverse flow backwashing filter, so that the adhesion to the quartz sand and activated carbon on the surface of the retentate and water stripping away, to restore the filtering function
