But the Heavy metals and pathogens will be reduced.Papermaking sludge is a bio-solid waste, which contains a large amount of cellulose-like organic matter and nitrogen, phosphorus, potassium and other plant nutrients, but also contains little heavy metals and pathogens....

Printing and dyeing sludge contains a large number of chemical residues, with high proportion of inherent water, is very difficult to dehydrate. After the mechanical filter, the sludge moisture content is still as high as 75 ~ 85%. However, the organic components in printing and dyeing sludge is very high. The calorific value of dry sludge can reach 2000kcal...
