Do you want to know how to recycle waste liquor from pulping equipment? How about the technology of washing and bleaching section?

Pulping Waste Liquor Recovery of Pulping Equipment

1) alkali recovery technology: (1) traditional alkali recovery technology of wood pulp; (2) alkali recovery technology of straw pulp; (3) direct alkali recovery (DARS method) (there is no successful example of production); (4) comprehensive utilization of white mud;

2) Development of process and equipment for improving black liquor extraction and evaporation efficiency;

3) Treatment of paper-making black liquor by plasma (there is no successful application in production yet).

4) Comprehensive utilization of cooking waste liquor;

5) Production of biogas by lime semi-chemical pulp (pilot test success)

Washing and bleaching section of pulping equipment

1) chlorine dioxide bleaching process;

2) Chlorine-free bleaching process (large investment, high cost);

3. White Water Recycling Technology of Paper Machine in Paper Mill Section

4. Comprehensive Wastewater Treatment System Outside the Plant Biochemical Treatment Technology (end) Environmentally Harmless Technology in Papermaking Industry
