83 DEVELOPMENT OF A TREATMENT SCHEME FOR SPENT CLEANING SOLUTIONS USING STATISTICAL PROCESS CONTROL CONCEPTS Kenneth E. Kaszubowski, Manager Solid Waste and Wastewater Compliance James A. Bilgo, Senior Environmental Chemist Kohler Co. Kohler, WI 53044 INTRODUCTION Kohler Co. is a world-wide manufacturer of commercial and household plumbing products, small internal combustion engines, generator sets, furniture, and other household goods. The manufacturing facility located in Kohler, Wisconsin, produces vitreous china, enameled cast-iron fixtures, brass plumbing fittings, and internal combustion engines. The Brass Faucets and Fittings Division of the Kohler, Wisconsin, facility manufactures brass plumbing fittings, which are finished by a variety of metal finishing operations within the Brass Building. The wastewaters generated by the metal finishing operations present significant challenges with respect to pollution prevention, optimization of waste treatment methods, and compliance with permitted effluent discharge limits. The manufacturing processes generate wastewaters which are highly variable in composition, volume, and flow rate. Many of the wastewater streams generated contain complexing agents which prevent the precipitation of soluble metal ions from a solution. In some cases, these streams are shipped off-site for treatment and disposal, at significant expense. The remainder of the streams are treated by conventional metal hydroxide precipitation in the Brass Waste Treatment (BWT) facility to meet categorical metal finishing standards. A simplified schematic diagram of the BWT facility is shown in Figure 1.
