Sand and stone filter using a certain thickness of sand filter bed, filter out the raw water and inorganic solids suspended solids;Simple structure, mature technology, cost-effective, wide range of applications.The filtration system can be composed of one or more standard high speed filtration units. The raw water passes through the internal water distributor, filter layer and water collector to effectively remove suspended solids and reduce turbidity.(if loaded with specific filter material, such as activated carbon, anthracite, etc., can also be adsorbed to remove the corresponding and harmful ions.)Sand and gravel filter filter units from 16 “(400mm) to 60” (1500mm) standard series;Also can according to the customer’s request, provides the non-standard series, for the customer is the economical practical combination way.The product can be used as a separate filter system or as a side filter system, which can be extended indefinitely if multiple processing units are installed on common pipes.Can be in the case of large flow and small pressure loss, long-term stable work, energy saving and environmental protection, basic maintenance free.
