On the sparse under the dense gradient density filter bed structure features:
High precision of filtration: the removal rate of suspended solids in water up to 95% or more, macromolecular organic matter, viruses, bacteria, colloids, iron and other impurities have a certain removal effect, after a good coagulation treatment of water,
5, low dosage, low operating costs: the filter bed structure and the characteristics of the filter itself, flocculant dosage is conventional technology 1/2 to 1/3.
backwash water consumption is low: backwash water consumption is less than the cycle of 1 ~ 2% of the amount of water;
3, the amount of pollutants: generally 15 ~ 35kg / m3, is more than 4 times the ordinary sand filter;
2, the filtration speed: generally 40m / h, up to 60m / h, is more than 3 times the ordinary sand filter;
