The effluent treatment plant is designed to treat the effluent i.e. Wastewater recycling coming from different areas of the plant.

Industrial Waste

Water is one of the most important components used in all types of industry. It is used in many processes of Industry. It may be used for washing, cooling, Heat Exchanging, condensing the steam etc. But Water used in industry is not consumed. Hence, almost all industries generate wastewater from industries that needs serious action. So improper discharge of wastewater can pollute the local environment. In many manufacturing Industries, by-products can be treated as wastewater called “Effluent” should be treated before its release into the environment.

Waste Water Treatment

Effluent is an outflow of water or gas from a natural body of water, or from a human made structure and in engineering, is the stream exiting a chemical reactor. It can also be defined as Treated or Untreated Waste water, that flows out of a treatment plant, sewage, or industrial outlet.

So this treatment of waste water i.e. untreated effluent is turned into Treated Effluent with the help of Effluent Treatment Plant (ETP) sometimes it is also called as Sewage treatment Plant (STP). Clean water then is safely discharge into Environment.

Industrial Waste Water

Industrial waste water treatment covers the mechanisms and processes used for waste water treatment that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer).

What are the Parameters Standards for ETP?

Effluent from industry must meet the National Standards for waste water set by Government. Effluent Treatment plant ETP or Sewage Treatment Plant (STP) should design & operated in such a way, that it treats the waste water to these standards.

Below are ETP Parameters with standards:

ParametersUnitsLimits
pH–5.5-9.0
Suspended Solidsmg/l100
CODmg/l250
Total Dissolved Solidsmg/l2100
Total Ammonical Nitrogenmg/l50
BOD 3 Days, 27 0Cmg/l100
Oil & Greasemg/l10
Chloride as Clmg/l600
Sulphate as SO4mg/l1000
Cyanidemg/l3
Fluoridemg/l2
Lead as pbmg/l0.1
Mercury as Hgmg/l0.01
Nickel as Nimg/l3
Zinc as Znmg/l5
Hexavalent Chromium Cr+6mg/l0.1
Total Metalmg/l10

 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.

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.

Learn More About Wastewater Treatment Methods.

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.

Learn More How Effluent treatment plant is designed?

ETP or STP Operation & Maintenance is Introduction of:

  • Various unit operations and processes (Separation by Screening, sedimentation , filtration, Neutralisation, coagulation, Flocculation, Absorption, Adsorption, Chemical Reaction, Oxidation/Reduction, Dissolution, Ion exchange, Chlorination)
  • Operation of Units such as Screens (Coarse / Fine Bar screens, Manual/ Mechanically operated), Sumps and Pumping Stations including Pumps, Motors and Panels (Centrifugal Horizontal / Vertical Turbine), Valves(Sluice gates, Non return, Reflux), Pipes/Specials and Pipe Joints, Grit Removal Units. Primary Sedimentation / Settling tanks, Scraping Mechanisms, Sludge withdrawal, Sludge Sumps, Sludge Pumps, Aeration tanks and Aerators, Secondary Settling Tanks, Secondary Sludge Sumps, Pumps, Sludge Thickeners, Sludge Digesters, Gas Production, Sludge handling and Drying.
  • Maintenance of Pumps and Motors, Electrical Panels (Starters, Meter, (Energy, Voltage, Amperage, Power factor), Blow out Fuses, Valves, Gates, Scraping Bridge Trolley, Aerators, Reduction Gears, Open Air Weather Casings for Motors, Sprocket wheels and Chains for Mechanical Grit and Screen removing devices.

Frequently Asked Questions:

How does ETP work?

The operation of the effluent treatment plant is divided into three categories. Primary Treatment involves separating sludge from the liquid using Sedimentation tanks. Secondary treatment involves the removal of biological or organic matter to reduce the bacterial population. Tertiary wastewater treatment often works by using a combination of physical and chemical processes to remove harmful microbiological contaminants from wastewater.

What is STP operation?

STP Operation involves the separation, removal and disposal of pollutants that exist in the wastewater. The treatment of wastewater is achieved by basic methods or techniques i.e. physical, mechanical, biological and chemical processes to remove impurities from wastewater.

How many levels of treatment are there in ETP?

There are three levels of the wastewater treatment procedure, known as primary (Separate sludge from liquid), secondary (Reduce biological population) and tertiary water treatment (to reduce harmful Chemicals).

What is the use of the ETP plant?

Effluent Treatment Plants or (ETP) are used by most of the companies in various industries to clean water and remove any toxic and non-toxic materials or chemicals from it so that that water can be reused or released in the environment which will do less harm to the environment.

What are the chemicals used in ETP?

As Per MPCB, Below are 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.

What is effluent treatment plant?

An Effluent Treatment plant is a unit plat where using multiple methods wastewater is treated for its reuse or safe disposal to the environment. This process reduces the demand of fresh water while keeping environment clean.

What is ETP plant maintenance checklist?

ETP Plant checklists are list of parameters to be checked at regular intervals to keep everything in check. This inspection technique helps inspection more specific, accurate and efficient. There are many types of checklists can vary based on types of plants and experience of managers.

What is the sequence of treatment process in ETP?

There are majorly three stages of wastewater treatment i.e., Primary, Secondary and Tertiary treatment. There are also substages in these processes such as bar screening, Aeration, Clarification, Chlorination, Water analysis, water testing and water disposal.

How do you maintain the pH of an ETP plant?

If the effluent in ETP is acidic then caustic soda (Sodium Hydroxide) is added to increase the pH and if the effluent is basic then hydrochloric acid or sulfuric acid is added to Main the pH of the ETP plant.
