TABLE IV.5.6 POLLUTION CHARACTERISTICS OF INDUSTRIAL WASTE 



Type of Industry 



Hrdance and Accessories 



Food and Kindred Products 



Tobacco Manufactures 

 Textile Mill Products 



Origin of Major Hastes 



Power plant, stack washing, leaching from ashes, lubrication and hydraulic oil spillage, 

 surface cleaning, treatlni, and painting, plating operations, trimming and buffing 

 operations, mllllnq with cutting oils. Repair and rework operations. 



Washinq of raw products, slaughtering, separation of skins, peels, pits, scales, feathers 

 and other Inedible fractions of crude products, rendering of fats, blanching, cooking 

 operation, curing and plckllnq operations, byproducts of too little value to market, 

 spills, floor and equipment cleaning, diffusion extraction operations, wet grinding 

 operations, steep tank liquors, still bottoms and cooling water. 



Mainly dry operations, some Incidental cleanup operations. 



Wool scouring, desizlng operations, cleaning, dyeing and bleaching. 



Apparel and Other Finished Products Made from Fabrics 

 and Similar Materials 



Lumber and Wood Products, Except Furniture 



Furniture and Fixtures 

 Paper and Allied Products 



Printing, Publishing, and Allied Industries 

 Chemicals and Allied Products 



Petroleum Refining and Related Industries 



Runner and Miscellaneous Plastic Products 



Leather and Leather Products 



Ory Operations. 



Leaching of logs being floated to mills and held in ponds for milling. Sawdust Is 

 potentially a heavy polluting agent if disposed so that It 1s washed Into surface waters 

 by storm runoff or 1f stored so that leachate reaches surface waters. Preservatives and 

 glues. 



Water curtain utilized to pick uo waste from varnishing, painting and finishing operations. 



Pulping operations. Including lrachlng of loqs and chips, chemical pulplnq treatments, and 

 Meaching operations. OebarUng processes. Condensate from reagent recovery evaporators. 

 Disposed fihers from paper-making. Glue, Ink and coloring agent spills. ieavy contami- 

 nation from production of tlaval stores. 



Mainly dry operation. Some waste from glueing and preparation of plates. 



Bleeding of recycle streams to avoid buildup of Impurities, wet scrubbing of stacks and 

 condenser exhausts, side reactions In many processes, add, alkaline and organic extrac- 

 tion agents. Impurities in raw materials, catalysts, unreacted monomers and other feed 

 reaqents, stabilizers, contaminated cooling water, dispersing agents, spent culture nedla, 

 cleanup and spills. 



Crude oil and process brines, cooling water from heat exchangers. Leaky heat exchange 

 equipment. Side reaction products from cracking and synthesizing operations, fractions 

 that escape collection by distillation columns. Stack washing, storage tank dratnoff 

 and spills. 



Most processes dry. Cooling water used in considerable quantity. Acid or alkali digesti* 

 of reclaimed rubber and washing of diqested product Acid, salt and alcohol coagulants for 

 latex processes. Wash water for latex processes. Lubricating and hydraulic oil spills. 

 Reagent spills and cleanup operations. Latex and reclaim processes greatest polluters. 



Wastes occur almost exclusively In tanning and finishing operation. Salting of hides, 

 leachate and scraping from hides, green fleshing, unbaring, bating, pickling, degreasing 

 and tanning. 



Stone, Clay. Glass and Concrete Products 



Grading of sand, clay and other mined components is major wastewater contamination source. 



Primary Metal Industries 



Cleaning and pickling acids. Various cleaning solutions and detergents. Otis for forming 

 operations. Coke guencMng and stack washing water, cooling water, molding and ore sands, 

 machining operations. Leaching agents for ores, flotation process, ore purifying. 



Fabricated Metal Products, Except Ordance, Machinery, 

 and Transportation Egulpment 



Machinery Except Electrical 



Machinery, Eguipment and Suoplles 



Lubricating and hydraulic oil spills from processmq equipment. Machining operations, flue 

 gas washing, metal cleaning operations paint spraying operation, electroplating anodizing. 



Water wash of stacks, blowdown of boiler, cooling tower residues, ion exchange wastes. 

 drainage from cinder and ash dumps, cuttinq oils, lubricating compound spills and rinse, 

 hydraulic oil leaks, sand blast dusts, dispersions, metal chips, metal surface cleaners, 

 corrosion prevention reagents, painting and plating operations. 



Metal forming operations, metal clean 

 and drilling of insulators. 



:ing operatl 

 , plating and painting operations. Cutting 



Transportation Egulpment 



Sta--k washing, cuttinq oils, spills of lubricating oils and hydraulic oils, pickling and 

 cleaning operations, plating operations, cooling water, blowdown of boilers, corrosion 

 protection, painting operations, and sanding.
