Problems of improving engineering procedures and processing flow diagrams for low- and medium-level liquid wastes

The process flow diagrams presently used for lowand medium-level liquid waste disposal produce large volumes of secondary waste that must be solidified and later buried. The cost of the expensive processes of solidification and burial must be reduced by perfecting precipitation, ion-exchange, evaporation, and other methods of treating liquid radioactive waste. The technical and economic indices of the operation of treatment facilities could be substantially improved if certain engineering procedures and process flow diagrams were employed: elimination of coagulation, breakdown of organic matter using ozone, preliminary desalination of waste by electrodialysis, and extraction of valuable components during waste concentration, and also if the technologies of continuous ion exchange and ultrafiltration were implemented.
