Characteristics of High Efficiency Filter

- Jan 03, 2019-

1. High filtration accuracy: the removal rate of suspended matter in water can reach more than 95%, which can remove impurities such as macromolecule organic matter, virus, bacteria, colloid, iron and so on. The treated water after good coagulation treatment, when the influent is 10 NTU, the effluent is less than 1 NTU.

2. The filtering speed is fast: generally 40 m/h, up to 60 m/h, which is more than three times of that of ordinary sand filter.

3. Contamination capacity is large: generally 15-35 kg/m3, which is more than 4 times of the ordinary sand filter.

4. The water consumption rate of backwashing is low: the water consumption of backwashing is less than 1-2% of that of periodic filtration.

5. The dosage of flocculant is 1/2-1/3 of the conventional technology due to the structure of the filter bed and the characteristics of the filter material itself. With the increase of periodic water production, the running cost per ton of water will be reduced.

6. Small area: Make the same amount of water, occupy less than 1/3 of the area of ordinary sand filter;
