product description
Continuous quicksand filter is a continuous filtration equipment. The system adopts the principle of up-flow fluidized bed filtration and a single homogeneous filter material. Filtration and sand washing are carried out at the same time. And the sand washing structure replaces the traditional high-power backwashing system, and the energy consumption is low. The system requires no maintenance, is easy to manage, and can be unattended. Due to the above advantages of continuous sand filter, it is widely used in the fields of industrial water, advanced sewage treatment and reclaimed water reuse.

working principle
The continuous flow sand filter is a high-speed filter integrating coagulation, clarification and filtration. It does not need to stop and backwash; it adopts single-stage filter material, no grading is required, and there are no problems such as uneven hydraulic distribution and primary filtrate; The backwash water pump and its electric and pneumatic valves for shutdown switching are required; there is no need to set up a single coagulation and clarification tank, and no mechanical equipment for coagulation and clarification. Therefore, the floor space is more compact and the running cost is more economical.
System Features
Space saving, precipitation and filtration functions can be completed in the same filter;
High filtration efficiency, 24 hours of continuous work, no need to stop backwashing. No need to backwash fans, pumps, valves and other ancillary facilities;
low operating costs;
Easy maintenance, the filter does not have any rotating parts except the filter material during operation, the failure rate is low, and the maintenance cost is low;
Excellent filter material is more resistant to wear, reduces wear and tear, and reduces operating costs;
The system runs automatically, and the operation is simple and does not require too much manual operation.
