Product Description:
One single continuous sand filter is divided into 4-6 compartments. The principle of continuous sand filter is a process in which filtration and backwash work at the same time. When the raw water flows through the water distributor after entering the water inlet, it flows down through the filter media, and in this process the sewage was intercepted by the filter media. The filtered water is collected and discharged by the water collecting compartment at the bottom of the filter. In the backwash process, close the inlet valve of the single compartment and open the backwash valve in sequence, the filter media in the collecting cavity is back washed by water in each cavity through gravity. After filtration and backwash, this kind of continuous sand filter can still keep the sand layer in place.
No need for backwash water pump with high-power, high flow, large pump lift to backwash the dirty sand filter. Automation degree is increased, and there’s no need for manual sand washing;
Without the need for downtime to achieve continuous filtration process.
The amount of chemical dosage is relatively small, saving processing cost. Low operating costs and high degree of automation;
No moving parts, reducing equipment maintenance workload;
High degree of automation. Operation is extremely simple——no need for backwash water pump and the corresponding pipes and valves;
