Difference Between ETP And STP?
For the benefit of society and our future, wastewater treatment is a crucial undertaking that needs to be treated with greater seriousness. To create a waste stream or solid waste that is appropriate for discharge or reuse, pollutants from both household sewage and wastewater must be eliminated through the process of wastewater treatment. There are three subcategories of wastewater treatment techniques: physical, chemical, and biological.
Let’s understand the difference between effluent treatment plant and sewage treatment plant!
What is an effluent treatment plant?
Leading pharmaceutical and chemical businesses to cleanse water and remove any harmful and non-toxic contaminants or compounds from it using Effluent Treatment Plant (ETP). All businesses employ these plants to safeguard the environment.
An ETP is a facility where wastewater and industrial effluents are treated. The pharmaceutical industry, for instance, uses ETP plants extensively to eliminate effluents from bulk pharmaceuticals.

An ETP is a facility where wastewater and industrial effluents are treated. The pharmaceutical industry, for instance, uses ETP plants extensively to eliminate effluents from bulk pharmaceuticals. In order to avoid polluting the receiving water, effluents must be treated. The effluent water treatment plants were put in place to lessen the likelihood of pollution; if biodegradable organics were not removed, the levels of contamination during the purification process might harm the bacterial treatment beds and pollute the controlled waters.
What is sewage treatment plant?
The process of purging impurities from sewage and household sewage, including domestic and runoff sewage, is known as sewage treatment plant. To remove physical, chemical, and biological impurities, it uses a variety of physical, chemical, and biological processes.
Its goal is to create a waste stream (or treated effluent) and solid waste (or sludge) that can be released into the environment or used again. This material frequently unintentionally contains harmful organic and inorganic chemicals.
How does sewage treatment works?
Before they damage or clog the pumps and skimmers of the primary treatment clarifiers, pre-treatment eliminates things that can be easily collected from the raw wastewater, such as trash, tree limbs, leaves, etc.
To get rid of all heavy items transported in the sewage stream, the influent sewage water is strained. In big, modern facilities, this is most frequently accomplished using an automated mechanically raked bar screen; but, in smaller, less advanced plants, screening may be accomplished with a manually cleaned screen.
Sewage passes through sizable tanks known as “primary clarifiers” or “primary sedimentation tanks” during the primary sedimentation stage. The primary sedimentation stage’s major goal is to create a generally homogeneous liquid that can be biologically treated as well as a sludge that may be treated or processed separately.
The purpose of secondary treatment is to significantly reduce the biological content of the sewage, which comes from soaps, detergents, food waste, and human waste. Most municipal plants use aerobic biological methods to treat the settling sewage liquor. The biota needs both oxygen and a substrate to live on for this to be effective.
Systems for secondary treatment might be either fixed-film or suspended-growth systems. However, compared to suspended growth systems, fixed-film systems can remove organic material and suspended particles at higher rates and are better able to handle abrupt changes in the amount of biological material. Roughing filters are designed to handle especially powerful or unpredictable organic loads, usually industrial, so that they can later be handled by standard secondary treatment techniques.
