In the process of industrial wastewater and domestic sewage treatment, a large amount of sludge will be produced. The moisture content in the sludge reaches 95% to 99%, as long as the water is removed, the volume of the sludge wil.....

Municipal sludge contains not only a large number of microorganisms, mechanical properties and rich nitrogen, potassium and other nutrients, but also excessive heavy metals, pathogenic microorganisms and so on. At present, the moi.....

he world's paper mills produce a large amount of papermaking wastewater, and the pollution load is heavy. Since the disposal cost of sludge accounts for about 50% of the sewage treatment cost, the sludge has not been properly disp.....

Sludge dehydrating agent is a chemical agent used for sludge treatment. Sludge dehydrating agent can accelerate the separation of water in the sludge, thereby reducing the volume and weight of the sludge and facilitating subsequen.....

With the improvement of the final disposal requirements of sludge, in order to improve the dehydration efficiency of the plate and frame machine, it is often necessary to use chemicals to tempering and treating the sludge, and the.....

As we all know, in order to meet the emission standards of paper mills, the moisture content must reach 55%-65%. At present, the methods of reducing water content mainly include chemical method, physical method and biochemical met.....
