ZK Wastewater Centrifuge for Paper & Pulp Waste Solutions
ZK industrial wastewater centrifuges provide an economical and effective solution for the solid-liquid separation and dewatering of sewage and sludge in paper mills. Especially in the recycling process of printing waste paper, the wastewater will accumulate abnormal residues, separated from the wastewater by a horizontal screw centrifuge, reducing production costs and reducing pollutant emissions. It can also reduce the emission of harmful substances as much as possible.
