Quartz sand filter layer thickness and flow rate on water turbidity

With quartz sand filter filtration experiment was carried out, using three kinds of filter layer thickness, 3 kinds of sediment concentration and 4 filtration velocity, the determination of water turbidity variation law with time, the analysis of the turbidity removal rate of each test.

the test results show that, with the raw water particle mass fraction is 0. Increasing the 0 03%. 08%, filtering ratio showed a trend of decline; Material quality, and the filter rate is inversely proportional to the filtration velocity, is proportional to the filter material layer thickness; Filter material layer thickness increases, filtering ratio increases, and the largest of its influence on filtering effect.
