EQUALISATION: The equalization tank's purpose is to balance the raw effluent from various processing units. The wastewater is collected in an existing mixed effluent tank and pumped to an existing aeration tank, which also functions as an equalisation tank.

What is the process of industrial effluent treatment plant?
Industrial effluent treatment plant process include the following stages: a. Preliminary Treatment:Its objective is physical separation of large sized contaminants. For example cloth, paper, plastics, wood logs etc. This level/process include:
What is the difference between common effluent treatment plant and ETP?
If the availability of land in your industry is less, then Common Effluent Treatment Plant (CETP) is preferred over Effluent Treatment Plant (ETP). Also find Effluent Treatment Plant
Which is the best effluent treatment plant in India?

Which level/processes occur in waste water treatment plants?
This level/process include: Screening:This is the first unit operation that occurs in waste water treatment plants. A screen is a device with uniform openings and its purpose is to remove large floating solids. Sedimentation:It is a physical water treatment process using gravity to remove suspended solids from water.
What is cod in ETP plant?
The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency. This test is based on the fact that a strong oxidizing agent, under acidic conditions, can fully oxidize almost any organic compound to carbon dioxide.
What are the effluent standards?
Effluent standards are concentrations of pollutants expressed in terms of parts per million for waste water discharged through outfall pipes from publicly owned sewage treatment plants or industrial plants.
What is effluent discharge?
Effluent discharge, sometimes referred to as 'wastewater', is liquid waste produced and discharged by any industrial or commercial premises, such as a food processing factory or manufacturing business.
What is effluent level?
The liquid effluent level, seen through the baffle or tank tee, will be just at the bottom of the septic tank outlet pipe. The floating scum layer may be several inches higher than that and should be blocked by the tank baffle.
What is a good BOD level?
A BOD level of 1-2 ppm is considered very good. There will not be much organic waste present in the water supply. A water supply with a BOD level of 3-5 ppm is considered moderately clean.
What is BOD and COD in ETP?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.
How many types of effluents are there?
2 Types of Effluent treatment plants you should know about Waste water treatment removes contaminants from waste water for the purpose of reuse or discharge. A waste water treatment plant is the physical infrastructure where waste water is treated.
How is effluent discharge calculated?
2:549:50Calculation of Wastewater flow rate - YouTubeYouTubeStart of suggested clipEnd of suggested clipWastewater is done by this formula. Q wastewater equals a K factor multiplied by the square root ofMoreWastewater is done by this formula. Q wastewater equals a K factor multiplied by the square root of the sum of the discharged units.
What is difference between sewage and effluent?
Sewage is a type of wastewater produced by a community of people due to activities like bathing, washing, cleaning. It also contains faecal matter. Effluent is the liquid waste that flows out of a factory and farm into water bodies such as rivers, ponds, and lakes.
What is the pH of a septic tank?
between 6 and 7.5A septic tank will usually have a pH between 6 and 7.5.
What pH should a septic tank be?
6.5-7.5But for bacteria to thrive in the septic tank, a pH of 6.5-7.5 is needed. It is therefore vital to maintain the wastewater in the septic tank within this range of pH in order to keep the microorganisms alive and well. When the septic tank pH gets higher than the recommended range, microbial activity will be inhibited.
What is effluent reduction?
An effluent limitation is a United States Clean Water Act standard of performance reflecting a specified level of discharge reduction achievable by the best available technology or related standards for various sources of water pollution.
What is an effluent treatment plant?
Have you ever wondered what is an effluent treatment plant? In simple terms, it is a complex system that works in several stages to turn the wastewater in industries into safe water.
How does an Effluent Treatment Plant Work?
Now that you have learned the answer to what is an effluent treatment plant, you may want to know how it works. In simple terms, effluent treatment plants mostly work in two stages.
Why should you have an effluent treatment plant?
An effluent treatment plant is important to maintain water quality. In the past few decades, many industries have started operating and producing thousands of tons of water.
What kind of Effluent Treatment Plant should you get?
What kind of effluent treatment plant you should get depends on how much wastewater your factory produces. You should contact an effluent treatment plant manufacturer to have the wastewater of your industry list down the contaminants that have to be removed to make the water safe.
What is Effluent Treatment?
Effluent Treatment is the process of removing solid, chemical, and organic substances from the wastewater produced by industries as an outcome of the production process and recycle the water for industrial use or discharge it into the environment safely.
Why is Effluent Treatment important for industries?
Industries use water in their production processes. For example, Pulp & Paper mills, water, cooling system, food & beverages, etc. Every industry needs to adhere to the government guidelines when they discharge the treated wastewater into the environment.
How does Effluent Treatment Plant work?
Effluent Treatment Plant (ETP) has many stages in treating the wastewater produced by the factories. The influent water has acid, oil, grease, and other solid substances like plastic, paper. The Effluent water is recycled back for industry use or discharged to the environment.
ETP Process Stages
Screening is the first stage where influent water enters. Oil skimmer, Bar Screens, and Grit chambers are used in this stage. An oil skimmer is a type of machine that removes the oil and grease floating on the water. Bar Screen is another piece of equipment that is used as a filter to remove large solid substances like plastic, paper, etc.
What is an effluent treatment plant (ETP)
Water as we all know is a crucial element for life and it cannot be wasted. Industrial wastewater treatment covers the mechanisms and processes used to treat wastewater that is produced as a by-product of industrial or commercial activities and produces a liquid effluent suitable for circulation into the process areas.
Source of Industrial Wastewater:-
Wastewater generated from agricultural and food operations is biodegradable and non-toxic, but has high concentrations of biochemical oxygen demand (BOD) and suspended solids. Vegetable washing generates waters with high loads of particulate matter and some dissolved organic matter.
Need Of ETP
Water is basic necessity of life used for many purposes, one of which is Industrial use. Industries generally pay heavy taxes for the raw water. But water once get used gets contaminated so it should be well treated so it can satisfy the proper prerequisites of usage in the plant.
