Ghanem H. Improving the efficiency of water purification, including liquid radioactive waste treatment

The dissertation is devoted to the development of technology for the preliminary treatment of contaminated waters from surface active substances (surfactants) and organic compounds (OC) for their further use in thermal and nuclear energetics, as well as technology for the purification of liquid radioactive waste (LRW). it is proposed to treat contaminated water with an electric discharge and ozone or ultrasound and ozone. In order to clean aqueous solutions of LRW, it was proposed to process them using ultrasound and ozonation in the presence of a sorbent - bentonite (SOK technology). The proposed cleaning method improves the efficiency of the subsequent stages of processing. The experimentally proven methodology for LRW purification can also be used to reduce the salt content, the concentration of surfactants and oils, and other pollutants. contaminated water purified from OC, surfactants and radioactive elements, it is proposed to evaporate an improved method - distillation with mechanical vapor compression (MVC). An algorithm has been developed for the static calculation of evaporators with MVC, which ensures the convergence of solutions in a wide range of parameters.
