Heat treatment of waste water sludges
https://doi.org/10.18412/1816-0395-2015-10-4-9
Abstract
The article describes different methods of heat treatment of wastewater sludges from plants and factories and gives the results of studies of convection heating and microwave heating of sludges of waste water from food production facilities. R&D activities alongside with analysis of foreign press on similar topics have resulted in determination of the optimal temperature of heating of wastewater sludges, as well as the relationship of heating temperature and microwave treatment time and treated liquid volume. Changes in wastewater sludge properties (sedimentation, transparency, COD) during the treatment and aerobic stabilization are identified.
