摘要

Mining and metallurgical waste waters are considered to be the major sources of heavy metal contamination. The need of economic and effective methods for metals removal have resulted in the development of new separation technologies. Precipitation, ion exchange, electrochemical proceses, filtration and flotation are commonly applied for industrial effluents treatment. Occasionally, the application of such processes is limited because of technical or economical constraints. The search for new technologies regarding the recovery and removal of toxic metals from waste waters has directed attention to membrane processes. These proceses are developed in the recent years due to the availability of many new types of membranes. This paper presents the laboratory test results for liquid radioctive effluent treatment from alkaline uranium ore processing by reverse osmosis.
