White Water Treatment and Pulping Equipment for Paper Mills
A sustainable paper manufacturing line requires efficient white water management and high-performance pulping equipment. Leizhan’s integrated solution includes a multi-disc filter for superior fiber recovery, multiple white water chests, and a network of pumps delivering filtrate to various process points. This paper mill machinery also features high-density cleaners, pressure screens, fractionation screens, and double disc refiners to optimize pulp quality. The paper production equipment operates at medium consistency, minimizing energy demand while maximizing contaminant removal.
By incorporating a closed white water loop, this paper making line reduces fresh water intake and effluent discharge, meeting modern environmental standards. The system’s advanced automation allows precise control of dilution, consistency, and pressure drops, ensuring stable operation of your paper machine. Whether you produce kraft liner, corrugating medium, or test liner, this complete paper processing line delivers consistent output with lower operating costs. Every component is built from stainless steel and wear-resistant materials, guaranteeing long service life in abrasive recycled fiber applications.
