What is the process of ETP plant?

What Is the Process of ETP & how to Treat Effluent Water?

  1. INITIAL OR PRIMARY FILTRATION. At first, wastewater comes from the industrial unit to the tank of the ETP.

How does waste water treatment plant work?

It works by using aeration and flocculation together. As we have seen, wastewater flows into an aeration tank and becomes mixed with water during aeration. Afterward, the wastewater flows into a settling tank or secondary clarifier.

What are the main steps in sewage treatment?

The Wastewater Treatment Process

  • Stage One — Bar Screening.
  • Stage Two — Screening.
  • Stage Three — Primary Clarifier.
  • Stage Four — Aeration.
  • Stage Five — Secondary Clarifier.
  • Stage Six — Chlorination (Disinfection)
  • Stage Seven — Water Analysis & Testing.
  • Stage Eight — Effluent Disposal.

How many types of ETP are there?

Basically, there are three types of treatment plants for water – water treatment plant (WTP), effluent treatment plant (ETP), and sewage treatment plant (STP). All of them have the sole purpose of treating wastewater.

What chemicals do ETP plants use?

Offering you a complete choice of products which include Poly Aluminium Chloride Liquid, Anionic Polyelectrolyte, Cationic Polyelectrolyte Powder, Poly Aluminium Chloride Powder, Caustic Soda Lye and Caustic Soda Flakes.

Why is ETP important?

Effluent Treatment Plants (ETP’s) are used by all leading industries to treat their wastewater. All the leading pharmaceutical, chemical, textile, and other industry that generate the wastewater used ETP’s to purify water and remove any non toxic or toxic materials or chemical from it.

What are the 3 types of wastewater treatment?

There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment.

What are the 5 steps of wastewater treatment?

Treatment Steps

  1. Step 1: Screening and Pumping.
  2. Step 2: Grit Removal.
  3. Step 3: Primary Settling.
  4. Step 4: Aeration / Activated Sludge.
  5. Step 5: Secondary Settling.
  6. Step 8: Oxygen Uptake.
  7. Sludge Treatment.

What is the purpose of ETP?

Effluent Treatment Plant or ETP is one type of waste water treatment method which is particularly designed to purify industrial waste water for its reuse and it’s aim is to release safe water to environment from the harmful effect caused by the effluent.

What are the 7 steps for water treatment?

They typically consist of several steps in the treatment process. These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.

Why ETP is used in industry?

An effluent treatment plant (ETP) is designed to treat these wastes or effluent. The treatment process by the ETP does not only reduce the damage done to the environment, but also results in other benefits for the industry.

What is wastewater treatment in simple words?

Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).

What is waste water called?

Wastewater is the polluted form of water generated from rainwater runoff and human activities. It is also called sewage. It is typically categorized by the manner in which it is generated—specifically, as domestic sewage, industrial sewage, or storm sewage (stormwater).
