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 macromolecular organic matter, viruses, bacteria, colloids, iron and other impurities. After good coagulation treatment, the treated water has an inlet of 10NTU and an outlet of less than 1NTU;
2. Fast filtration speed: generally 40m/h, up to 60m/h, more than 3 times that of ordinary sand filters;
3. Large pollution holding capacity: generally 15-35kg/m3, more than 4 times that of ordinary sand filters;
4. Low backwash water consumption rate: The backwash water consumption is less than 1-2% of the cycle filtration water volume;
5. Low dosage and low operating cost: Due to the characteristics of the filter bed structure and the filter material itself, the flocculant dosage is 1/2-1/3 of the conventional technology. With the increase of cycle 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 the ordinary sand filter;
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 service life of more than 20 years.
