Wastewater treatment Wastewater treatment Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a byproduct of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is ...

Wastewater System Wastewater Sludge Drying Process. Sludge Drying involves the process of reducing water content in the sludge generated by using the principle of vaporization of water In conventional sludge drying beds in effluent wastewater plant vapor pressure differences is the main driving force for evaporation to take place to the atmosphere.
Biogas generation comprises comminuting and mixing untreated refuse with nondehydrated clarifying sludge by a 2 or multistep grinding process, pref using a 2 or multi compartment ball mill. The sludge obtd is swelled for several hrs. All sludge components incapable of rotting, including plastics, are sepd by one or more flotation processes.
Dec 10, 2019· At Stora Enso''s Heinola fluting mill, biosludge is a byproduct of wastewater treatment. Previously, the mill would burn the biosludge at the power station for thermal power, but because it is so wet, it needed fossilbased fuel to support the burning process.

Rapid oxidative degradation can be used for the direct disposal of sludge waste or pretreatment before the dehydration step. Methods for reducing oil content of sludge . For mechanical treatment of the sludge, a sonicator, a ball mill, and a homogeniser were used to separate the phases of the sludge by applying shear force.
Stirred ball mill(SBM) method is one of the usually method which applied in large scale application cases of sludge disintegration. This study focuses on investigation the mechanism of sludge disintegration by SBM method. Besides analysis general indicators of SCOD, TN, TP and calculated the disintegration rate of COD (DDCOD). The result indicated the SCOD and DDCOD increased with the ...
A process for resolving even tightly emulsified oil, water and solid emulsions by the application of a sheer force sufficient to break the emulsion. In one particular application, a tank bottom sludge produced in the petroleum industry is treated with the shear force of a bal or roller mill into the emulsion is broken. Simultaneous reduction in the particle size of the solids occurs.

Sludge acidification to a pH less than with sulfuric acid is another technique that was found to result in significant sludge reduction (WPCF 1989). In Germany, a novel approach to reducing sludge production involved the use of an agitator ball mill to disintegrate bacterial cell walls, thereby releasing an external carbon source for
