AVAILABILITY OF SEMIPERMEABLE MEMBRANES SEPARATION TECHNIQUES FOR THE TREATMENT OF LIQUID RADIOACTIVE WASTE

Abstract

The semipermeable membranes separation techniques (like: microfiltration, ultrafiltration and reverse osmosis) concern a wide range of radwastes that includes solutions, which are usually putting serious problems during treatment operations. A relevant example is given by the wastes issued from the decontamination operations which contain large quantities of detergents and complexant agents. The paper presents several experimental tests by membrane techniques carried out on a pilot scale device at Institute for Nuclear Research Piteşti. The purpose of the experimental study was to elaborate and evaluate an adequate technology for treatment of low salt content liquid radioactive waste, by using indigenous semipermeable membrane.
