INTRODUCTION INDUSTRIAL WASTEWATER IS ONE OF THE IMPORTANT POLLUTION SOURCES IN THE POLLUTION OF WATER ENVIRONMENT. DURING THE LAST CENTURY HUGE AMOUNTS OF INDUSTRIAL WASTE WATER WAS DISCHARGED IN TO RIVERS, LAKES AND COSTAL AREAS.

• This resulted in serious pollution problems and caused negative effects to the ecosystem and human’s life.

TYPES OF INDUSTRIAL WASTEWATER THERE ARE MANY TYPES OF INDUSTRIAL WASTEWATER BASED ON DIFFERENT INDUSTRIES AND CONTAMINANTS. GENERALLY INDUSTRIAL WASTEWATER CAN BE DIVIDED IN TO TWO TYPES:

SECTOR POLLUTANT IRON AND STEEL OIL, METALS, ACIDS, PHENOLS AND CYANIDES TEXTILES AND LEATHER SOLIDS, SULFATES AND CHROMIUM PULP AND PAPER SOLIDS, CHLORINATED ORGANIC COMPOUNDS PETROCHEMICAL AND REFINERIES MINERAL OILS, PHENOLS AND CHROMIUM CHEMICALS ORGANIC CHEMICALS, HEAVY METALS AND CYANIDE NON FERROUS METALS FLUORINE MICROELECTRONICS ORGANIC CHEMICALS MINING METALS, ACIDS AND SALTS

INORGANIC INDUSTRIAL WASTEWATER �WASTEWATER PRODUCED MAINLY FROM � COAL AND STEEL INDUSTRIES � COMMERCIAL ENTERPRISES � INDUSTRIES FOR SURFACE PROCESSING OF METALS (ELECTROPLATING PLANTS)

EFFECTS OF POLLUTION • EFFECTS on environment • �Biodegradable wastes deplete DO in the receiving stream affect the flora and fauna. • EFFECTS on humans • �Diseases caused by: • �Drinking contaminated water • �Swimming in polluted water • �Contact with chemically polluted water

• EFFECTS on animals • �Human-created waste that has deliberately or accidentally become afloat in a lake, sea, ocean or waterway. • � 200 turtles in Australia’s surround waters die each year • EFFECTS on birds and mammals • �Birds and mammals become coated with oil

CONTROL MEASURES �SOME INDUSTRIES ARE SUCCESSFULLY REDESIGNING THEIR MANUFACTURING PROCESSES TO REDUCE OR TO ELIMINATE POLLUTANTS THROUGH A PROCESS CALLED POLLUTION PREVENTION. �INDUSTRIES GENERATING LARGE VOLUMES OF WASTEWATER TYPICALLY OPERATE THEIR OWN COMPLETE IN-SITU TREATMENT SYSTEMS.

WHAT WE CAN DO • REFUSE : Say NO to water pollution • RRECYLE : Recycle water • REDUCE : Minimize use of water

SAFE WATER SAVE LIVE!!!
