Pay attention to us
1. High filtration accuracy: the removal rate of suspended solids in water can reach more than 95%, and it has a certain removal effect on impurities such as macromolecular organic matter, virus, bacteria, colloid, iron, etc. The treated water after good coagulation treatment, When the inlet water is 10NTU, the outlet water is below 1NTU;
2. Fast filtration speed: generally 40m/h, up to 60m/h, which is more than 3 times that of ordinary sand filters;
3. Large amount of pollutants: 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 1-2% of the periodic filtration water consumption;
5. Low dosage and low operating cost: Due to the structure of the filter bed and the characteristics of the filter material, the dosage of flocculant is 1/2 to 1/3 of the conventional technology. With the increase of the periodic water production, the operating cost per ton of water is also reduced;
6. Small footprint: to produce the same amount of water, the footprint is less than 1/3 of that of ordinary sand filters;
7. Strong adjustability. Parameters such as filtration accuracy, interception capacity, and filtration resistance can be adjusted as needed;
8. The filter material is durable and has a life span of more than 20 years.
