Reduction, stabilization and harmlessness of sludge thickening and dewatering process

- Nov 14, 2018-

Reduction of sludge thickening and dewatering process: due to the high moisture content of the sludge, large volume and liquidity, after the above process, the sludge volume is reduced to one tenth of the original, and The liquid is converted to a solid state for easy transportation and consumption.

Stabilization of sludge thickening and dehydration process: The sludge contains high content of organic matter, which is highly prone to spoilage and produces foul odor. After the treatment in the digestive stage of the above process, some of the easily spoiled organic matter is decomposed and transformed, which is not easy to be spoiled, and the malodor is greatly reduced, which is convenient for transportation and disposal.

The harmlessness of sludge thickening and dehydration process: sludge, especially the primary sludge, contains a large number of pathogenic bacteria, parasitic eggs and viruses, which easily cause large-scale spread of infectious diseases. Through the digestion stage in the above process, most of the aphid eggs, pathogens and viruses can be killed, and the sanitary indicators of the sludge are greatly improved.
