What is COD and BOD in ETP water?
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.
What are effluents?
Definition of effluent: something that flows out: such as.a : an outflowing branch of a main stream or lake.b : waste material (such as smoke, liquid industrial refuse, or sewage) discharged into the environment especially when serving as a pollutant.

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 an effluent waste?
So effluent waste comes really from the process. So it’s not, we’re not really talking about it for industry, and our assets is toilet waste, and handwashing and, and toilet waste. We’re looking here really is what’s used? Why do you use water and liquids within the processing? You might see them at a brewery.
How do Effluent Treatment plants impact water pollution prevention?
So what you’ve normally got with Effluent Treatment plants is you’ve only got bulk storage. It’s a is a bulk storage of either of chemicals that’s used to obviously balance their Effluent Treatment plants.
What does an Effluent Treatment plant look like?
Well, an Effluent Treatment plant really, you could look at it really, you’ve got normally a below ground potentially discharge point where it goes across a little knife gate you’re aware, which allows it back into the, to the waterways or into a sewage treatment farm, or, and then you only have bulk storage, so the material comes into a balancing tank which is sat there that there may be posted.
What are the risks associated with managing an Effluent Treatment plant?
So once you put an Effluent Treatment plant, you may have had permit changes, because obviously, you’ve now got much more bulk storage that you probably didn’t have before. Before your process of having an Effluent Treatment plant, you might have just been discharging to the water company every day, specific way.
What special considerations are there in managing an Effluent Treatment plant?
So this is quite a new area where experiences as a business is a question that’s been asked by customers that are buying or installing or running Effluent Treatment plants. What they’re finding is the regulator. The environment agencies turning up and saying, “Can you address CIRIA c736? You’ve got all this bulk storage of chemicals.
How have we been involved with managing Effluent Treatment projects?
So I have to say in recent times, we’ve had phone calls from sites that are implementing a new Effluent Treatment plant, which is created the requirement for changes to their environmental permits, which is brought the regulator on site. The regulator’s question is “Right.
What is your recommendation for anyone implementing or managing Effluent Treatment Plants?
So I think if I was looking at putting in a new Effluent Treatment plant, which means potentially you’re going to be changing your permits, which means what we know the environment is going to get involved because I’ve been looking at what you’re doing.

Which process removes heavier particles from the bottom of the water?
Sedimentation:- In this process water moves slowly, causing the heavy particle to settle to the bottom. The particles that collect at the bottom is called sludge.
What is used to adjust pH?
For alkali waste (High PH):-Acids are used to adjust PH. Coagulation:- In this process, liquid aluminium sulphate is added to untreated water. After mixing, this causes tiny particles of dirt to stick together. This group of particle form larger and heavier particles, which is easily removed by settling and filtration.
What is effluent treatment plant?
The effluent treatment plant is a special water treatment solution designed to decontaminate industrial wastewater. This method of purification allows companies to reuse wastewater in other procedures and protect the environment from hazardous chemicals of industrial effluent.
What is biological treatment?
Biological treatment also named as the secondary treatment is used to take all the residual organic and nonorganic matter out of the water.
