DY-250 Sludge Specific Resistance Determination Training Platform

Release time：2024-06-25 10:00viewed：times

1. Experimental purpose:
Sludge specific resistance (or specific impedance) is a comprehensive indicator of sludge dewatering performance. The larger the sludge specific resistance, the worse the dewatering performance, and vice versa. This experiment determines the specific resistance of activated sludge, using FeCl3 and Al2(SO4)3 as coagulants.
It is hoped that the following objectives will be achieved through the experiment:
1. Master the experimental method for determining sludge specific resistance;
2. Master the selection of coagulants using the Buchner funnel test;
3. Master the method for determining the amount of coagulant to be added.
