Lucky ratio blocking test device

The sludge ratio (or ratio impedance) is a comprehensive indicator of sludge dehydration performance. The greater the sludge than the resistance, the worse the dehydration performance, and the better the dehydration performance. The ratio of the active sludge in this experiment is tested with FeCl3 and AL2 (SO4) 3 as a concrete.

I hope to achieve the following goals through experiments:

1 Master the experimental method of determining sludge ratio;

2 Master the choice of concrete with a British funnel test;

3 Master the method of determining the coagulant.
