| Abstract |
Exchange diffusion(Donnan dialysis) with ion-exchange membranes was investigated as a potential process for the removal of nitrate, phosphate and ammonia from secondary sewage plant effluents. Using commercial ion-exchange membranes and plate-and-frame configuration ninety percent removals were obtained in laboratory and pilot scale experiments. Ammonium removal appears to be economically feasible while a combined nitrate-phosphate system is only marginally economic at the present state of development. Improvements in cell configuration and membranes are suggested as a means of improving the process costs. |
