Filter characteristics

1. High filtration accuracy: The removal rate of suspended solids in water can reach more than 95%, and it can remove macromolecular organic matter, viruses, bacteria, colloids, iron and other impurities to a certain extent. The treated water after good coagulation treatment, When the inlet water is 10NTU, the outlet water is below 1NTU.

2. Fast filtering speed: generally 40m/h, up to 60m/h, which is more than 3 times that of ordinary sand filters.

3. Large dirt holding capacity: generally 15～35kg/m3, which is more than 4 times that of ordinary sand filters.

4. Low water consumption rate for backwashing: the water consumption for backwashing is less than 1 to 2% of the periodic filtering water.

5. Low dosage and low operating cost: Due to the filter bed structure and the characteristics of the filter material itself, the dosage of flocculant is 1/2 to 1/3 of conventional technology. The increase in cycle water production reduces the operating cost per ton of water;

6. Small footprint: the same amount of water is produced, and the footprint is less than 1/3 of that of ordinary sand filters.

7. Strong adjustability. Parameters such as filtration precision, interception capacity and filtration resistance can be adjusted according to needs.

8. The filter material is durable and has a service life of more than 20 years.
