What is Effluent Treatment Plant and ETP Working Process

ETP (Effluent Treatment Plant) is a process design for treating the. industrial waste water for its reuse or safe disposal to the environment. Netsol Water is leading consultant, manufacturer, and supplier of ETP plant in India.
Effluent Treatment Plant:
Effluent Treatment Plant
Effluent Treatment plant can be operated with the help of 4 diff ways:
1) Preliminary - Removal of Solids, Oil & Grease.
2) Primary - Removal of floating & settable such as Suspended solids, Organic Matter
3) Secondary - Removal of Biodegradable organic matter (BOD).
4) Tertiary - Removal of residual suspended solids, Dissolved solids.
What are the chemicals used in ETP?
As Per MPCB, Below is the list of general chemical used in ETP
1. For pH neutralization: Acids (HCl) and base (NaOH)
2. Coagulant / Settling Aids: Aluminium Sulphate, Ferric Aluminium Sulphate, Ferric Sulphate, Ferric Chloride, these may be independent or in combination with Poly Electrolytes (Polymers)
3. For Specific Ion removal, chemicals required as per chemistry of treatment.
4. Nutrients: Urea, Di-ammonium Phosphate
5. Disinfectant: Chlorine, Bleaching Powder (Sodium Hypo-chlorite), Ozone
6. Adsorption / Absorption: Activated Carbon
7. Ion Exchange - based on the specific ion to be removed.
Operation & Maintenance of ETP or STP:
The Effluent Treatment plant once constructed/established need to have operation & maintenance through qualified & experience persons to serve efficient & effective operation of ETP, qualified operator & supervisor are being provided by Perfect Pollucon Services who maintains all the records of the operation and attends the day to day trouble shooting.

Effluent or Sewage Treatment plant Operation and Maintenance Staff Requirements:
The manpower requirement for ETP or STP Operation and Maintenance can broadly be listed as follows:
1) Plant Manager: is an individual with environmental engineering or science /Graduate or Post Graduate Background with experience of at least three years on similar plant(s).
2) Plant Operator(s): is an Individual with at least a High School Pass with sciences and be physically fit and mentally alert. Comprise a team of qualified / trained operators who work in shifts in operating and maintaining screens, grit removal devices, pumps, aerators, valves, etc.
3) Laboratory Analyst: is a qualified individual should be at least B.Sc. with Chemistry who has knowledge of water and waste water chemistry and is trained in preparation of laboratory chemicals, use of laboratory instruments, collection and preservation of water / waste water samples and analysis for various environmental parameters such as pH, SS, BOD, COD, TDS etc.
Above staff is used to run ETP or STP effectively which gives proper result set by respective Govt.
