Abstract

The report gives results of a study of the treatment of wastewater, from a textile mill producing synthetic knit fabric for the apparel and automotive markets, with a system combining biological (activated sludge) and chemical (alum coagulation) processes. The treatment consisted of: heat recovery; equalization; completely mixed activated sludge with sedimentation and nutrient supplement; and alum coagulation with sedimentation, polymer addition, and pH adjustment. The activated sludge process effectively removed degradable organics and ammonia nitrogen. The alum coagulation process effectively removed colloidal organics, suspended solids, orthophosphate, and certain metals. Total treatment system removals for BOD, COD, and color were 92, 73, and 69 percent, respectively. Capital cost of the system was $1.15 million with a yearly operating expense of $269,030, including capital cost depreciation. Additional treatment was required to meet anticipated discharge limitations. Appropriate research studies were conducted using carbon adsorption, resin adsorption, and ozonation for residual, soluble color removal. Portions of this document are not fully legible.
