description Expansion of the municipal wastewater treatment plant in Grand Island, Neb., was necessitated by the construction of a major meat packing facility. Because of the nature of the wastes, it was decided to construct a complete mixing activated sludge plant (CMAS). Operating data covering 2.5 yr is analyzed. Ninety-five percent BOD reduction and 91 percent suspended solids reduction was realized in January, 1969. Improved operation during the following 5 months resulted in a 98 percent reduction through the aeration tank. The evaluation of CMAS data yielded information which was useful in setting the operation pattern of the treatment plant.
