How to treat the waste sludge in Leather and Paper-making industry?

In March, ZJN technicians investigated three companies in Shandong and Hebei as required.

Two private enterprises of manufacturing leather in Hebei, produce lots of sludge when producing leather; Leather sludge must be treated with harmless disposal as per national standard, which is highly sticky, highly humid with much organic and moisture content. The two enterprises have tried many ways but the final effect is always bad and unsatisfactory. Since knowing “Rotary Harrow Rolling Triple Level Multi-loop” Dryer of ZJN, they promptly make call to us and urgently invite our engineers to see their sludge situation.
