The sand filter uses a sand filter bed with a certain thickness to filter out organic and inorganic solid suspended solids in the raw water; the structure is simple, the technology is mature, the cost performance is high, and the application field is wide.
The sand filter 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, and uses the filter layer medium to effectively remove suspended solids and reduce turbidity.
(If a specific filter material is loaded, such as activated carbon, anthracite, etc., the corresponding organic matter and harmful ions can also be removed by adsorption.) Sand filter filtration units range from 16" (400mm) to 60" (1500mm) standard series; according to customer requirements, non-standard series can also be provided, which is the most economical and practical combination method for customers.
It can be used as an independent filter system or as a side filter system. If multiple processing units are installed on the common pipeline, the filter capacity of the system can be expanded infinitely. It can work stably for a long time under the condition of large flow and small pressure loss, energy saving and environmental protection, and basically maintenance-free.
