| Abstract |
Biological and chemical means of phosphorus removal were studied at Metro Seattle's activated sludge facility in Renton, WA. The studies ranged from jar tests to full-scale plant manipulation. Only the secondary activated sludge system was studied. The results of these studies indicate that the observed removal of phosphorus, in a soft water area activated sludge facility, is primarily biological in nature. Both ferric chloride and alum are effective in removing phosphorus and both can be controlled by automatic means. Initial capital costs for either chemical are the same except for larger storage tank for alum. |
