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 type 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 totally consumed. Hence, almost all industries generate waste water from industries that needs serious action. So, improper discharge of waste water can pollute local Environment. In many manufacturing Industries, by-product can be treated as waste water called “Effluent” should be treated before it release into the environment.

Effluent is an outflow of water or gas from a natural body of water, or from a human made structure.

Effluent, in engineering, is the stream exiting a chemical reactor.

Effluent is 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).

National Standards for Waste Water

Effluent from industry must meet the National Standards for waste water set by Government. So, 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.

Parameters	Units	Limits
pH	–	5.5-9.0
Suspended Solids	mg/l	100
COD	mg/l	250
Total Dissolved Solids	mg/l	2100
Total Ammonical Nitrogen	mg/l	50
BOD 3 Days, 27 0C	mg/l	100
Oil & Grease	mg/l	10
Chloride as Cl	mg/l	600
Sulphate as SO4	mg/l	1000
Cyanide	mg/l	3
Fluoride	mg/l	2
Lead as pb	mg/l	0.1
Mercury as Hg	mg/l	0.01
Nickel as Ni	mg/l	3
Zinc as Zn	mg/l	5
Hexavalent Chromium Cr+6	mg/l	0.1
Total Metal	mg/l	10

 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.

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.

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.
