Common Effluent Treatment Plant (CETP) is used for treating combined effluents generated from a cooperative group of small industries. Effluent Treatment Plants need land for its construction, large capital, power, and specialized manpower for its operation and maintenance. A normal ETP Plant cost a large amount of these resources which is not affordable to have its own effluent treatment facilities for small and middle scale industries. Now Common Effluent Treatment Plant plays a big role by treating the combined effluent from all small and mid –sized industries at a centralized place. These small scale industries formed a co-operative group for Common Effluent Treatment System or Government Local bodies are also providing the same with a minimum charge of treating their industrial waste.
CETPs are designed to collect and treat effluents from a multitude of facilities, to deal with various qualities and quantities of effluent.
Advantages of Common Effluent Treatment Plant
There are many advantages of using CETPs by small scale and mid-size industries, some of the advantages are listed below-
1 - Saving Capital Cost and skipping Installation of individual ETP plant
2 - Saving Operation Cost of ETP
3 - Specially Designed for Small and Mid-sized Industry
4 - Better treatment at one location
5 - Land Conservation /Availability of Land
7 - Easy Operation and Maintenance
8 - Low Cost by shared expense
“Common effluent treatment plant (CETP) for wastewater management from a cluster of small scale industries”
As you know, treating the effluent came from industry is mandatory. There are many industries, which is small or entry level or mid-sized, that they are not able to install their own Effluent Treatment Plant just because of Lack of Land / space, Resources, Specialized Manpower, Budget or any other issue. CETP help to solve their problems.
Small industry can for a Cooperative group or any government local body or any individual group can provide these small scale industries for a specific location to treat their industrial wastewater before discharging it into nature. The Common ETP is very helpful for red category flagged industry like chemical and textile for their highly polluting type of effluent and requires treatment measures before disposal.
How Common Effluent Treatment Works
The CETPs design and treatment units comprised an equalization tank (with neutralization and surface aeration) and a clari-flocuulation unit, an aeration tank with an activated sludge process, and a final outlet. Below given image shows you best view of Common Effluent Treatment Plants-
What is Combined Effluent Treatment plant?
What is common and Combined Effluent Treatment? CETP concept is evolved to facilitate collective treatment of effluents from various industries at a centralized facility, to avail benefit of scale of operation, maintenance and skilled manpower. Such plants are referred as combined effluent treatment plants.
