I’m also facing the problem of difficult sludge dewatering

The sludge from a cardboard box factory recently comes from the wastewater from the printing workshop; this sludge is sent to the sludge tank. There is a strange phenomenon in this tank: the sludge floats to the surface, with water at the bottom and sludge on top. Currently, the screw pump draws water from the bottom, and this water containing very fine particles is sent to the filter press. After operating all night, the filter press was found to be empty, containing only some very soft, mushy sludge. My preliminary analysis suggests that it’s either a problem with the filter cloth, or there needs to be a sludge concentration tank added along with cations. Everyone, do you think there are any other possible causes?
