The sludge in the biochemical wastewater treatment filter press cannot be pressed out
Thread Content
In biochemical wastewater treatment, sludge presses fail to separate sludge from water; when coal powder is added to the sludge, it gets compressed into cakes. Without adding sludge, water and sludge remain mixed together – what is the reason for this?
Wood powder can also be added… the roughness should be low; it won’t be solid without pressure
It’s too sticky; adding coal ash can reduce the viscosity of the sludge, improve water permeability, and at the same time turn the sludge into mature sludge.
It’s not clear whether you have anaerobic sludge or aerobic sludge; if it’s anaerobic sludge. Under normal circumstances, the anaerobic treatment effect is poor and the sludge has a high affinity for water, making separation difficult; if it is aerobic sludge, try adding an appropriate amount of polyacrylamide and polyaluminum chloride!
The reason for improper use of the flocculant is that it is recommended to replace it
