Solid and Hazardous Waste Disposal

sludge treatment and disposal

On the basis of introducing and absorbing advanced technologies which come from Germany, Japan and other countries, Longking has created a sludge treatment solution which is suitable for China. This solution reduces the sludge moisture content from 80% to 60%~10% and the maximum reduction rate can reach 78%, which can meet the treatment and disposal requirements of municipal sludge, industrial sludge and other sewage sludge, and further realize the resource utilization of sludge.
