Principle
Quartz sand filter is the use of quartz sand as a filter medium, under certain pressure, to filter high turbidity water through a certain thickness of the granular or granulated quartz sand, effectively interceptive remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions from water, ultimately reduce water turbidity, purify water effect as an efficient filtration equipment.
Functions
It uses silica sand as filter material to fill filter to facilitate removal of impurities in the water, also has other advantages such as small filtration resistance, large specific surface area, strong acid resistance and good stain resistance. Its unique advantage that by optimizing the design of the filter and the filter, to implement filter's adaptive operation, filter material has strong adaptability on raw water, operating conditions, pre-disposal technology, that is automatically filter bed formed under tight state memorial while filter, make for ensure water quality under various operating conditions, backwash filter fully spread for good cleaning effect. Sand filters can effectively remove suspended solids, and obviously removal of colloid, iron, organics, pesticides, manganese, bacteria, viruses and other contaminants in water, and has a fast filtering rate, high filter fineness, high filtration capacity, etc. It is mainly used on deep disposal area of electricity, beverage, tap-water, petroleum, chemical industry, metallurgy, textile, papermaking, food, swimming pools, municipal engineering and other process water, domestic water, cycling use of water and waste water.
