TABLE IV.5.6 POLLUTION CHARACTERISTICS OF INDUSTRIAL WASTE 



(continued) 



Major Wastes Characteristics Treatment 



Suspended solids as fly ash. metal powder, paint solids, domestic wastes 

 and miscellaneous cleanup solids. Cutting, lubricating and hydraulic oils, 

 neterqents and organic cleaning agents. Cyanide and heavy metals. 



Heat, hlqh BflD and suspended solids, detergents, nitrogenous substances, 

 fat, orqanlc adds, salts, large operations cause severe nuisance growth; 

 animal pathogen hazard. 



Plant control. 01) separators, flocculatlon and sediment action. Cooling 

 systems. Buffer lagoons. Aerobic biological treatment. Use of municipal 

 system. 



Process control, keeping water use at a minimum and exclusion from waste- 

 water screens, fat separators, sedimentation, biological treatment and 

 municipal plants, separation of solids for landfill or barging to sea, 

 disinfection. 



High BOO, heat and suspended solids, adds, bases, bleaching agents, deter 

 gents and dyes with high coloring activity. Many waste components have 

 bioddal action. 



Municipal plants. 



Process control, physical, chemical biological, particularly activated 

 sludge and aerated lagoon. Municipal plant. 



Very little water pollution 



Large amount of BOO In leachate from loas and from sawdust. Some 

 blocidal contaminant in leachate and In preservative snills. 



Munidoal nlant. 

 Process control 



Solvents, niqment, varnish solids. Hinh BOD and bioddal components. 



Very hiqh suspended solids, BOD. heat, oil, acid, alkali, color and 

 blocidal component problem. The volume is larqe and treatment difficult. 



Process control chemical, sedimentation, boi -oxidative, municipal plant. 



Process control, chemical precioi tation, neutralization, sedimentation and 

 centrlfuqation. All tvnes of Moloqical treatment. Laqoons , landfill and 

 irrmation. Controlled discharge on outqolnn tides. 



Some BOD glueinq and addic metal solutions from plate preparation. 

 Verv limited source of cvanlde from platinn operations. 



Adds, alkalies, salts, flammable and bioddal orqanic compounds in 

 nreat varietv, suspended solids, oils, phosphorous, sulfides, cvanides, 

 heavv metals detergents, elastomer dispersions and fluorides. Hiqh 

 BOD loads. 



Various oily components. Phenolic compounds. Sour waters containing sul- 

 fides and mercaptans. Ammonia. Cyanide. Pyridine. Spent caustic solutions. 

 Various detergents. Hot streams. Various sludge components. Chromates. Bio- 

 ddal agents. Chemicals that cause fish flavors, a major wastewater problem. 



Large quantity of hot water. Sulfur zinc compounds and wide variety of 

 blocidal organic compounds. Organic adds and BOD components. Discolora- 

 tion from carbon black. Detergents and suspended sol Ids. 



Process control, chemical, physical, municipal nlant. 



Process control, chemical, neutralization, oxidation, precipitation, sedi- 

 mentation, oil separation, bio-oxidative treatment with adapted svstems, 

 particularly activated sludged and aerated laqoons. Many wastes require 

 isolation and snedal treatment. Buffer laqoons heln handle difficult 

 loads. Burning of separated solids or oils. 



Physical, chemical, oxidation, cooling, neutralization, oil separation. 

 sedimentation, bio-oxidation in adapted systems, particularly activated 

 sludge and aerated lagoons. Flotation, electrostatic separators and 

 centrifugation. 



Process control, physical, acclimated bio-oxidative system. 



Salt, animal fluids, protelnaceous compounds, fat, suspended flesh, 

 sulfide and ammonium salts, deterqents. organic solvents, vegetable and 

 chrome tanning agents. Very high BOD and nuisance promotion components. 

 Components with bioddal action. 



Suspended solids from mineral grading in large quantity, when mining asso- 

 ciated with manufacture. Small amount of suspended solids from qrlndlng 

 and cutting operations. 



Fly ash, metal chips and powder. Iron salt solutions, adds, bases, 

 chromium, variety of organic chemicals, cyanide, oils, deterqents, 

 sulfides, ammonia, fluorides and heat. Volume hugh. 



Oils, metals powder and chips, detergents, paint solvent and solids, 

 chromic add, phosphoric add, cyanide and heavv metals. 



Suspended solids, oils, detergents, acidic metal salts, organic solvents, 

 cyanide, ammonia, fluerlde, phenolic compounds, phosphoric and chromic 

 adds. Many substances unfavorable to aquatic organisms. 



Process control, chemical coagulation, sedimentation, bio-oxidative 



treatments. 



Sedimentation. 



Process control, chemical, physical neutralization, precipitation, oil 

 separation, flotation, magnetic separation, acclimated b1o-ox1dat1 ve systems 

 particularly activated sludge and aerated lagoons. High speed mills and 

 deteriorating ore quality leading to more waste. Heep wells. No 

 separation of fluorides. 



Process control, chemical, sedimentation, oil separation, Mo-oxidation, 

 municipal plants. 



Process control, chemical, oil separation, sedimentation, bio-oxidation, 

 municipal plant. 



Metal chips and powder, other suspended solids, oils, adds, detergents, 

 cyanide, heavy metals, paint solvents and solids. These industries are 

 not regarded as heavy polluters but carry on operations that consistently 

 lead to polluted water. Plating baths are a serious hazard and demand 

 close control . 



nils, metal chips, detergents, adds, iron salts, cyanide, heavy metals. 

 fly ash. paint solvent and solids and alkaline waste. Many components 

 with blocidal activity. 



Process control, double tanking of cyanide baths, chemical, oil separation, 

 sedimentation, hio-oxidation and municipal plant. 



Process control, chemical, physical sedimentation, oil emulsion, breaking 

 and separation, special isolation and destruction of cyanide wastes, 

 bio-oxidative treatment with acclimated systems.
