Investigation of the Processing of Biological Sediments by the Cryogenic Method
https://doi.org/10.18412/1816-0395-2020-10-20-25
Abstract
The study of the processes of intensification of sludge dewatering at sludge sites of sewage treatment plants (WWTP) is presented. The parameters that determine the water yielding capacity of the compacted and excess activated sludge have been clarified. The process of cascadecyclic freezing – thawing of biological sediments has been investigated. The degree of influence of cryogenesis on the specific resistance of the sediment filtration and its water yielding has been determined. Dependences of the resistivity of precipitation on the content of ashless substance and freezing temperature have been established.
