The residual sludge moisture content discharged by the biochemical system is generally 99.5% ~ 99.8%. After concentration and ordinary mechanical dehydration, the moisture content of the sludge is still as high as 80%, and further.....

The water content of the mud pressed out by the filter press is very high, and the mud is very thin, and the reasons need to be analyzed from several aspects. Such as the plate and frame machine, whether there is a bad water perme.....

The 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 dis.....

At present, the basic status and drawbacks of the agents used for sludge deep dehydration: the actual operation of the sludge deep dehydration process shows that the dosage of agents is high, and once the dosage of agents is reduc.....

In the current sludge treatment, polymer inorganic sewage flocculant is usually added for flocculation dehydration, that is, polymer bridge flocculation can also neutralize the negative charge on the sludge, increase the cohesion .....

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.....
