Chemical treatment is the process used to treat the CDTN's aqueous liquid radioactive waste, and its purpose is to reduce the volume of waste to be cemented. In the process, radionuclides and other contaminants present in the waste are precipitated/coprecipitated, such as hydroxides, carbonates, sulfates and phosphates. The sludge formed is separated by decantation and incorporated into cement. The supernatant is filtered, analyzed and released when below the elimination limit. All stages of the treatment are monitored by means of laboratory tests aiming at greater treatment efficiency and quality control of the final product.
