Industrial Effluent Treatment Plant

It can be observed that, the generation of industrial wastewater is overwhelming due to rapid development of various industries which produce its own particular combination of pollutants are extremely contaminate the surrounding environment. Hence, environmental rules have directed all the industrial units to implant effluent treatment plant to curb the direct release of untreated wastewater in water bodies.

Here, are some of the major industries which need to implant Effluent Treatment Plant (ETP) to purify the waste water before it gets discharged are:
1. Food and processing industries
2. Pharmaceutical industry
3. Textile and Paper industries
4. Automobile industries
5. Textile and dye industry
6. Dairy and Beverage industries

1. How does industrial effluent pollute the environment?

Industry is a vital source of water pollution. Industrial effluent diminishes the aesthetic quality of water courses such as ponds, lakes, rivers and etc. It causes significant effect to human health. Moreover, contaminated wastewater (untreated effluent) includes both organic and inorganic matter destroys marine life and reduces its reproductive ability. Diversity of impurities in industrial effluents has been tied to many serious health issues and damage to natural environments.

2. What is industrial effluent treatment?

Industrial effluent is any wastewater that is produced by various industrial activities. The quality of industrial effluent/wastewater varies from one industry to another is responsible for the degradation of receiving water sources. In other words, treating all kinds of effluents originating from various industries using industrial ETP/Effluent Treatment Plant is extremely desirable.

Industrial effluent treatment is the effective process of treating waste water that is highly contaminated by industrial wastes, making it fit for reuse or dispose/discharge back to the natural environment.

3. Different levels of treatment involved in Industrial Effluent Treatment Plant or ETP:

Wastewater treatment technology includes physical, chemical, and biological methods. Depending on the type and extent of contamination, various treatment levels involved during the treatment of industrial effluent are shown in below table:

Treatment Level Description Process involved
1. Preliminary Treatment or Pretreatment Removal of large solids such as rags, ticks, grit and grease that may damage equipment or result in operational problems. It uses bar screens and grit chamber to remove these suspended solid materials. Physical
2. Primary Treatment It involves removal of floating and settleable materials such as suspended solids and organic matter. It removes about 70-80% of suspended solids and 25-30% of BOD. Sludge that settles to the bottom of the primary clarifier is pumped out and subjected for sludge processing. Physical and chemical
3. Secondary Treatment Removal of biodegradable organic matter and suspended solids. It involves most preferred biological aerobic process called “activated sludge process” which effectively removes about 85% of organic matter. Biological and chemical
4. Tertiary or Advanced Treatment It takes out residual suspended solids or dissolved solids. It improves the quality of treated water in order to comply with discharge standards. It involves a process called disinfection (uses disinfectants like chlorine, ozone, UV light in common) for removing any undesirable microbes. Physical, chemical and biological
