Quartz sand filterMainly, it mechanically retains and adsorbs some suspended solids, particles, and colloids in water. Make suspended particles overlap and bridge each other. So after a period of time, an additional filter membrane seems to form on the surface of the filter layer, which plays the main filtering role in future filtration. This type of filtration is called "membrane filtration". Depending on the inflow situation, the filling material is generally1.5Replace around once a year. As shown in the figure1-21）As shown.

Activated carbon filterMainly remove free chlorine from water to avoid the oxidation of ion exchange resins, especially cation exchange resins, in chemical water treatment systems by free chlorine. The second step is to remove organic matter from the water, such as humic acid. Based on our years of experience and calculations, it can remove water60%～80%Colloidal substances,50%Left and right iron and50%～60%Organic matter.

The removal effect of activated carbon on impurities in water is based on the unsaturated chemical bonds on the active surface of activated carbon. Due to the large surface area of activated carbon（500～1500m²／g）In addition, the surface is covered with an average diameter of20～30Due to the uneven energy distribution of carbon atoms on the surface of activated carbon, which contain unsaturated bonds (referred to as "residual valence bonds" in some literature), there is a tendency for chemical reactions with foreign molecules or functional groups, resulting in strong adsorption capacity for certain organic compounds.

Softened water processor,Reduce the hardness of water by adsorbing calcium, magnesium, potassium, and sodium ions in the water onto the resin in the water softener. Within a certain period, the ions adsorbed on the resin are washed out through industrial salt. Then perform forward flushing and backward flushing. This can reduce the hardness of the water.
