- Post-treatment. ...
What is primary treatment of wastewater treatment plant?
Tube Settler/Lamella Clarifier
- It is a compact inclined plate type clarifier. ...
- To provide a large projected area like clarifier lamella clarifier is used which is based on the principle of settling heavier particles under gravity, providing a number of inclined plates.
- Settling capacity is increased by the use of the tube settler. ...

What causes high nitrate in effluent?
- Nitrification is a bio-chemical reaction that occurs inside bacteria.
- Two species of bacteria are involved in the process – Nitrosomonas and Nitrobacter.
- These bacteria are collectively known as nitrifiers and are autotrophic, i.e. they get their carbon source from inorganic carbon (carbonates, bicarbonates) or carbon dioxide.
What is meant by effluent treatment plant?
• ETP (Effluent Treatment Plant) is a process design for treating the. industrial waste water for its reuse or safe disposal to the environment.
Whats the meaning of ETP?
Key Takeaways. Exchange-traded products (ETP) are types of securities that track underlying security, index, or financial instrument. ETPs trade on exchanges similar to stocks. The price of ETPs fluctuates from day-to-day and intraday. The share price of ETPs come from the underlying investments that they track.
What is effluent explain?
Effluent comes from the Latin verb effluere, "to flow out". In an older meaning, an effluent was a stream flowing out of a river or lake. But nowadays effluent almost always means wastes that pour into our water and air. Liquid factory waste, smoke, and raw sewage can all be called effluents.
Why is ETP important?
Effluent treatment plant cleans industrial effluents, contaminated water from outlet pipes, reservoir, rivers, lakes etc and reclaim the water resource for using in different purposes. ETP are mostly installed in industries like textile industry, Medicine manufacturing, leather industry, and chemicals industry.

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. Effluent does not contain the excreta of humans.
How many types of effluents are there?
There are three types of wastewater, or sewage: domestic sewage, industrial sewage, and storm sewage.
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 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.
1. Effluent Treatment Plant (Zero Liquid Discharge) for Distillery Industries
The Distillery industries utilize molasses and different grains as raw materials.
2.Effluent Treatment Plant (Zero Liquid Discharge) for Electroplating Industries
Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. Electroplating is widely used in industries such as automobile, airplanes, electronics, jewelry, and toys.
3. Effluent Treatment Plant (Zero Liquid Discharge) for Pharmaceutical and Bulk Drug Industries
The pharmaceutical industry develops, produces, and markets drugs or pharmaceuticals licensed for use as medications.
4. Effluent Treatment Plant (Zero Liquid Discharge) for Pulp & Paper Industries
Paper is a major product of the forestry industry, and is used widely in our society. Paper is made by pulping wood, bleaching this pulp and then spreading it out into sheets to make it into paper. At various stages of the process, chemicals are used to give the paper particular properties, such as the bleaching chemicals that make paper white.
Where does effluent go?
Effluent usually flows from the premises directly into the main sewer network and it cannot enter a river, reservoir, stream or lake unless it is cleaned and treated first. Food waste.
What are the challenges of wastewater treatment?
There are six challenges shaping the future of effluent treatment, including: 1 Decreasing operational costs; 2 Optimizing to improve efficiency; 3 Stricter environmental regulations; 4 Water scarcity & the push for reuse; 5 Changing technology; and 6 Subproduct recovery.
What is the EPA's sewage guidelines?
Effluent Guidelines are national regulatory standards for wastewater discharged to surface waters and municipal sewage treatment plants, according to the U.S. EPA. The EPA issues these regulations for industrial categories, based on the performance of treatment and control technologies.
How much of the suspended solids in wastewater are removed?
Primary treatment removes about 60% of suspended solids from wastewater, according to USGS, and secondary treatment removes more than 90% of suspended solids.
