Abstract
Phosphorus removal was implemented at the full-scale, 1mgd, Texas City, Texas, activated sludge plant. Over a two-year period, several techniques were investigated. Control of the plant operations to enhance biological removal of phosphorus was not a reproducible process. The most efficient means of controlling phosphorus was by the use of iron salts added to the raw waste water or primary effluent. Aluminum salts were slightly less effective. All aspects of plant operation were investigated, such as excess sludge production and drainability of digested sludge. Estimates of the operating costs associated with phosphorus removal are presented.
