Textile Industry

Textile dyeing and finishing produces coloured effluent treated by coagulation-flocculation and biological processes, yielding a chemical-physical sludge with hydroxide and dye residues. The screw press dewaters this often gelatinous sludge steadily, with polymer conditioning tuned to the specific chemistry. Low rotational speed and self-cleaning gaps prevent the screen blinding that fine hydroxide sludges cause in other presses, keeping capture rates high.
