CMF+AE for EU Waste Water

A great deal of research has been directed towards the problem of the treatment of waste water contaminated by uranium, and lots of processes available in nuclear facility. However, the key problem is that the existing processes are mainly applied for depleted uranium (DU), but not for enriched uranium (EU). So, it's imperative to develop a process for EU waste water treatment which comes from nuclear facility decommission or others.Consequently, the new process coagulation micro-filtration (CMF) combined with anion exchange (AE) was established to deal with the EU waste water. The experiments was divided into three parts CMF, AE and CMF+AE, respectively. The experiment results revealed that CMF is capable to deal with the waste water(the concentration of uranium in original waste water was 4.29 mg/L) at the pH 6.0-7.0, and its decontamination factor (DF) reached 103;AE is good at treating the original waste water when the concentration of which is not more than 500 g/L, meanwhile, the residence time is not less than 10 minutes, therefore, the treated water by AE meets the discharge standard; The DF number of the combined CMF + AE process might get 104.According to our research, the CMF + AE process provides a new choice for EU waste water treatment.
