APPARATUS FOR THE TREATMENT OF AN EFFLUENT

摘要

A process for the treatment of an effluent is provided and includes the steps of removing entrained solids and organic compounds from the effluent, preferably by means of filtration; removing uranium from the effluent using a strong base anion resin; removing cations from the effluent using a strong acid cation resin and eluting the resin with nitric acid to provide a cation eluate; removing anions from the effluent using a weak base anion resin and eluting the resin with ammonium hydroxide to provide an anion eluate; neutralising evaporating the cation eluate to obtain a 50% mixed metal nitrate solution; and neutralising and evaporating the anion eluate to obtain substantially dry ammonium salt. The process results in the economic production of water, a uranium solution, a mixed metal nitrate solution and an ammonium salt from a hazardous waste product.
