Effluent Treatment Plant (ETP) Technology for Waste Water Treatment

Effluent is generally considered as water pollution, flowing out of a factory, farm, commercial establishment, or a household into water bodies such as a river, lake, streams, ponds or a sewer system. Nowadays effluent has gained a wider coverage as it includes almost every waste that pour into our water and air. Liquid factory waste, smoke, and raw sewage can all be called effluents. Industrial effluents contain various materials, depending on the type of industry. Some effluents contain oil and grease, some contain toxic materials too, and effluents from food and beverage factories contain degradable organic pollutants. Since industrial waste water contains a diversity of impurities and therefore specific treatment technology called ETP is required.

Effluent Treatment Plants are another form of waste water treatment plant which are designed and manufactured specially for treating water that contains effluents and working towards making the water effluent-free. The Effluent Treatment Plant (ETP)works at different levels and involves various processes such as physical, chemical, biological and membrane processes to treat waste water from different industrial sectors including chemical, pharmaceutical, refineries, dairy, hotel, restaurant & textile etc.

Water is most important part in everyone’s life, be it personal life or industrial life. No one can live without water and even no production can occur without it. Hence, it becomes necessary to utilize the available water to the maximum extent or not to dispose the same hazardously. However, the quantity used by different industries may differ due to different usage but still much of the important task such as washing, drinking, dilution etc. are performed through water. If the industry has a right to use water, then it becomes their duty to make it clean or re-usable. Industries consumed the clean water and generate the polluted water which includes harmful chemicals such as oils, grease, solids etc. water produced through the industrial process is called “waste water” or “Effluent”.

 Our duty is to clean the pollutants through the effective water treatment methods. So, plants are established for this process and these plants are called “Effluent Treatment plant (ETP)”. As the name suggest, it involves removing the pollutants under the water to make it usable for another process and then to make the environment pollution free.

Advantages:

· Discharge waste free water

· Eliminates municipal fees

· Production materials can be recovered for re-use

· Recycling of water so eliminates unused water.

According to Department of Environment, effluent must be according to the quality standards set by the government and so the ETP should be established and directed accordingly.
