Reverse-Osmosis Filtration Based Water Treatment and Special Water Purification for Nuclear Power Systems

This paper is devoted to the development and operation of specialized water treatment and water purification systems, based on the principle of reverse-osmosis filtration of water, for the operation of bench nuclear power systems at the A. P. Aleksandrov Scientific-Research and Technological Institute. Reverse-osmosis filters permit softening the process water, improving its quality, and greatly decrease the load on the ion-exchange filters when desalinating water. Ultimately, the contamination of drain waters with dissolved salts is also greatly decreased. The drain waters can also be purified by a combination of reverse-osmosis and ion-exchange filters. A modular membrane-sorption system whose capacity reaches 0.5 m3/h is presented.
