Quartz sand filter is a filter medium using quartz sand. Under certain pressure, the high turbidity water is filtered through a certain thickness of granular or non granular quartz sand. It can effectively intercept and remove the suspended matter, organic matter, colloid particles, microorganism, chlorine, smell and some heavy metal ions in the water. An efficient filtration equipment for low turbidity and purifying water quality.
Quartz sand filter is usually used as the pretreatment of reverse osmosis equipment and ultrafiltration equipment. It is mainly to intercept and adsorb silt, colloid, metal ion and organic matter. Commonly used filter materials are quartz sand, activated carbon, anthracite, manganese sand and so on.
Quartz sand filter is made of one or several filtration media, operating at room temperature, acid and alkali, and oxidation. The pH is 2-13. The system is equipped with a perfect protection device and monitoring instrument, and has the function of backwashing. The dirt and other pollutants are quickly washed away, and the water consumption is less. The automatic function can be set according to the requirements of the user. Under certain pressure, the raw liquor can be flocculated, adsorbed and withdrawn through the medium to remove impurities so as to achieve the purpose of filtration. The fillers are generally made of quartz sand, anthracite, granular porous ceramics and manganese sand. Users can choose to use them according to the actual situation.
Compact structure: the equipment integrates coagulation reaction, filtration and continuous cleaning. The water treatment process is simplified, the floor area is small, the structure is simple, and the installation operation is flexible and convenient. The energy consumption and manual management cost of the raw water treatment process are reduced, and the operation difficulty is reduced.
the effect of coagulation reaction is obvious: the application of coagulation mechanism and settlement mechanism can effectively remove suspended matter and colloid substance in water, which is beneficial to further reducing the turbidity of the effluent in the sand filtration area.
Continuous self-cleaning filtration: filter medium automatic circulation, continuous cleaning, no need to shut down for backwashing.
The content of the suspended substance (SS) of the raw water is reduced: with the micro flocculation device, all kinds of industrial water, urban sewage and industrial water for *SS less than mg/L are used as reused water, and the removal rate is more than 90%, so as to achieve the perfect filtration effect.
Special material, long service life.
Quartz sand filter is mainly used for pretreatment of turbidity, softening water, electrodialysis and reverse osmosis, and can also be applied to surface water and groundwater. It can effectively remove suspended matter, organic matter, colloid, sediment and so on.
It can be widely used in electronic power, petrochemical, metallurgical, electroplating, paper and textile, pharmaceutical dialysis, food and beverage, drinking water, water of factory enterprises, swimming pool and so on. It can meet the needs of liquid filtration in various industries.
Quartz sand filtration is one of the effective means to remove suspended solids in water. It is an important unit for advanced treatment of wastewater, sewage reuse and water treatment. Its function is to further remove the pollutants that have been flocculated in water. It achieves the purpose of water purification by interception, sedimentation and adsorption of filter materials.
