What is a Common ETP (CETP)?

A CETP is an arrangement wherein a number of participants come together at a centralized place for collection of each of their effluents and get those treated with an Effluent Treatment facility. The concept of CETP is adopted to vail the benefit of scale of operation.

Why a Common ETP?

Municipal Effluent Treatment Plants are expensive projects in terms of capital cost, land for construction of the plant, power and specialized manpower for their operation and maintenance. Due to these constraints, medium and small scale sectors and households cannot afford to have their own effluent treatment facilities. Therefore, as a solution, the effluents from all individual participants from such medium and small sectors are collected in a common place for treatment. This arrangement or facility is called a Common Effluent Treatment Plant (CETP). Medium and Small scale tanners form a co-operative society so that a CETP can be formed, operated and managed. The expenses for operation and maintenance of CETP are shared by participating tanneries. Wastewater management for the cluster of small-scale participants becomes cost effective as well efficient by the installation of a CETP.

Q1. What is an effluent treatment plant?

Ans. An Effluent Treatment Plant is a unit facility where wastewater is treated for reuse or safe disposal to the environment using a variety of ways. This method minimises the demand for fresh water while also keeping the environment clean.

Q2. How does ETP work?

Ans. The effluent treatment plant's functioning is divided into three groups. Sedimentation tanks are used in first treatment to separate sludge from liquid. Secondary treatment is removing biological or organic matter to minimise the bacterial population. Tertiary wastewater treatment frequently use a combination of physical and chemical methods to eliminate potentially dangerous microbiological pollutants from wastewater.

Q3. What are the chemicals used in ETP?

Ans. The chemicals listed below are commonly used in ETP.

  • Acids (HCl) and bases for pH neutralisation (NaOH)
  • Coagulant: Aluminium Sulphate, Ferric Aluminium Sulphate, Ferric Sulphate, Ferric Chloride, either alone or in combination with Poly Electrolytes (Polymers)
  • Chemicals required for specific ion elimination based on treatment chemistry.
  • Urea, Di-ammonium Phosphate are two nutrients.
  • Disinfectants: chlorine, bleaching powder (sodium hypochlorite), and ozone
  • Activated Carbon Adsorption
  • Ion Exchange - depending on the ion to be eliminated.

Q4. How many levels of treatment are there in ETP?

Ans. The process of treating wastewater consists of three levels:

  • Primary (separate sludge from liquid)
  • Secondary (decrease biological population)
  • Tertiary water treatment (to reduce harmful Chemicals).

Q5. What is the use of the ETP plant?

Ans. Most companies in a variety of industries utilise effluent treatment plants (ETPs) to purify water and remove any toxic and non-toxic materials or chemicals from it so that it can be reused or released in the environment with less environmental harm.

Q6. What are the methods of ETP?

Ans. These are the Common methods of treatment of Industrial Wastes (ETP):

  • Neutralization cum Equalization
  • COD/BOD Ratio
  • Chemical Coagulation and Precipitation
  • Settling Treatment
  • Segregation
  • Monitoring of ET P
  • Oxidation and Reduction
  • Disinfection
  • Adsorption by Activated Carbon
  • Stripping
  • Thermal Processes
  • Tertiary Treatment of Sewage
  • Removal of Colour
  • Disposal of Solid Wastes
