Diagnostic procedures for aquaculture biofilter media are as follows:
Check the oxygen consumption rate SOUR of the sludge. If SOUR is lowered, it means that the sludge is poisoned, and the cause of the poisoning should be analyzed and treatment measures should be taken.
If there is foam in some aeration tanks but the others do not, check whether the water distribution between each tank is even, and whether the return sludge entering each tank is evenly distributed. If a certain aeration tank enters a lot of sewage, but distributes less return sludge, the tank is prone to foam.
Phenomenon 2-- A fine dark brown foam is formed on the surface of the aeration tank.
