 ETP treats the waste materials into neutralized molecule or
reduces the harmful ingredients. Industrial wastewater
treatment covers the mechanisms and processes used to treat
waters that have been contaminated in some way by
anthropogenic industrial or commercial activities prior to its
release into the environment or its re-use.
 This effluent contains several pollutants, which can be
removed with the help of an effluent treatment plant.
 ETP treat water and make free from all objectionable
impurities present in suspension, colloidal or dissolved form.
 Stay in compliance
 Reduce hauling and off-site treatment costs
 Eliminate municipal fees
 Reduce supply costs by recovering production materials out of
the waste-stream for re-use
 Eliminate unnecessary water usage during processing
 Protection of public health
 Solving social problems caused by the accumulation of
wastewater
 For groundwater recharge
 For industrial recycle

 Ion-exchange
 Nutrient Removal
 Preliminary treatment removes gross solids and materials that
can be easily collected from the effluent and can damage or
clog the pumps and skimmers of primary treatment clarifiers.
 These are in-organic materials and insoluble organic pollutants
(i.e. large floating and suspended solid matter, grit, oil &
grease) which are inert and cause problems to further chemical
and biological treatments.
 The presence and sequence of preliminary treatment units are
totally depend upon the characteristic of effluent that is to be
treated.
 All preliminary treatment consist of physical separation
techniques by controlling flow rate of effluent.
 Primary treatment consists of temporarily holding the sewage
in a inert basin where heavy solids can settle to the bottom
while oil, grease and lighter solids float to the surface.
 The settled material go for sludge treatment and floating
materials are skimmed off. The remaining liquid is passed to
secondary treatment.
 Tanks are usually equipped with mechanically driven scrapers
that continually drive the collected sludge towards a hopper in
the base of the tank where it is pumped to sludge treatment
facilities.
At this stage, over 70% of the suspended solids and 40% of the
BOD is removed from effluent.
 Secondary treatment is a biological treatment of effluent
which is typically performed by indigenous, water-borne
micro-organisms in a managed habitat.
 Secondary treatment removes dissolved and suspended
organic (bio-degradable) matter by consuming it as a food and
convert it into new cell mass, energy and CO2.
 The most common micro-organisms are bacteria (aerobic or
anaerobic), protozoa and rotifers; least common are fungi and
algae.
 After secondary treatment almost 70-90% of BOD and 80-
90% of dissolved solids are removed from effluent.
 Tertiary treatment is the final treatment, meant for ‘polishing’
the effluent and removal of pollutants not removed in primary
and secondary treatment.
 These pollutants may include soluble inorganic compounds
such as phosphorous or nitrogen which may support algae
growth in receiving waters.
 Also removes organic materials contributing BOD, COD,
color, taste, odor; bacteria, viruses, colloidal solids
contributing turbidity; or soluble minerals which may interfere
with subsequent re-use of the wastewater.
 Preferred when treated water is need to be reuse or discharge
is into a highly sensitive or fragile ecosystem (estuaries, low-
flow rivers, coral reefs, etc).
 Tertiary treatment add additional cost to the treatment process
but produce high quality effluent which can be reuse further
for commercial and industrial applications.
 Treated water can be reuse for the irrigation of a golf course,
green way or park, construction work, industrial process, etc.
If it is sufficiently clean, it can also be used for groundwater
recharge.
 Treated water is sometimes disinfected chemically or
physically depending upon the discharging location.
 Equalization: The raw waste from the main plant is first collected
in the equalization tank through screening.The equalization tank is
designed for a hydraulic retention time of around 6 hours and is
avoided with air grids connected to air blowers for maintaining the
solids is suspension
 Effluent Mixer Flocculation Tank & Clarifier: The equlized
waste is then pumped into the flask mixer compartment of flash
mixer & flocculation tank where coagulant is dosed and polymer in
the flocculation compartment to aid the process of settling. The
overflow from the flocculation compartment is taken into the
clarifier for removal of suspended solids and BOD/COD.The
overflow from the clarifier is taken for further treatment while the
underflow is taken for sludge compartment.
 Biological Treatment: The neutralized effluent will this the
treated through the Bio Tower with aeration tank and clarifier.
The liquid overflow from the Lamella clarifier is taken to the
chlorination tank. The sludge underflow from the Lamella
clarifier is partially returnedto the inlet of the aeration tank for
maintaining the desired level. The excess sludge is treated
through a basket type centrifuge.
 Filtration: Chlorinated water will be passed through a
Multigrade Sand Filter for further reduction of suspended
solids to less then 20 ppm and then passed through a activated
carbon filter for the polishing of BOD, COD values.
 Sludge Treatment: The under flow from the clarifier and the
secondary clarifier having a sludge consistency of around 1-
1.5% is pumped into the centrifuge for dewatering. The
dewatered sludge is then disposed off suitably while the
concentrate is taken back to the equalization tank
Thank You!

Effluent treatment plant

  • 2.  ETP treats the waste materials into neutralized molecule or reduces the harmful ingredients. Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use.  This effluent contains several pollutants, which can be removed with the help of an effluent treatment plant.  ETP treat water and make free from all objectionable impurities present in suspension, colloidal or dissolved form.
  • 3.  Stay in compliance  Reduce hauling and off-site treatment costs  Eliminate municipal fees  Reduce supply costs by recovering production materials out of the waste-stream for re-use  Eliminate unnecessary water usage during processing  Protection of public health  Solving social problems caused by the accumulation of wastewater  For groundwater recharge  For industrial recycle
  • 4. Parameter Gov’t Standards PH 6.5 to 8.5 BOD 30 mg/lit COD 100 mg/lit Suspended solids 100 mg/lit TDS Approx. 2100 mg/lit Oil & Grease 10 mg/lit Chlorides 600 mg/lit Temperature 40°C

  • 6. Preliminary Treatment  Screens  Detritor/scrapers  Grit Chamber  Skimming Tanks  Aeration Primary Treatment  Sedimentation/ Settling tank  Clarifloculator  Equalization Tank  Neutralization Tank Secondary Treatment  Activated Sludge Process  Trickling Filter  Aerated Lagoons  Multiple Evaporator Tertiary Treatment  Sand/ Membrane Filters  Activated Carbon Filters  Disinfection  Ion-exchange  Nutrient Removal
  • 7.  Preliminary treatment removes gross solids and materials that can be easily collected from the effluent and can damage or clog the pumps and skimmers of primary treatment clarifiers.  These are in-organic materials and insoluble organic pollutants (i.e. large floating and suspended solid matter, grit, oil & grease) which are inert and cause problems to further chemical and biological treatments.  The presence and sequence of preliminary treatment units are totally depend upon the characteristic of effluent that is to be treated.  All preliminary treatment consist of physical separation techniques by controlling flow rate of effluent.
  • 8.  Primary treatment consists of temporarily holding the sewage in a inert basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface.  The settled material go for sludge treatment and floating materials are skimmed off. The remaining liquid is passed to secondary treatment.  Tanks are usually equipped with mechanically driven scrapers that continually drive the collected sludge towards a hopper in the base of the tank where it is pumped to sludge treatment facilities. At this stage, over 70% of the suspended solids and 40% of the BOD is removed from effluent.
  • 9.  Secondary treatment is a biological treatment of effluent which is typically performed by indigenous, water-borne micro-organisms in a managed habitat.  Secondary treatment removes dissolved and suspended organic (bio-degradable) matter by consuming it as a food and convert it into new cell mass, energy and CO2.  The most common micro-organisms are bacteria (aerobic or anaerobic), protozoa and rotifers; least common are fungi and algae.  After secondary treatment almost 70-90% of BOD and 80- 90% of dissolved solids are removed from effluent.
  • 10.  Tertiary treatment is the final treatment, meant for ‘polishing’ the effluent and removal of pollutants not removed in primary and secondary treatment.  These pollutants may include soluble inorganic compounds such as phosphorous or nitrogen which may support algae growth in receiving waters.  Also removes organic materials contributing BOD, COD, color, taste, odor; bacteria, viruses, colloidal solids contributing turbidity; or soluble minerals which may interfere with subsequent re-use of the wastewater.  Preferred when treated water is need to be reuse or discharge is into a highly sensitive or fragile ecosystem (estuaries, low- flow rivers, coral reefs, etc).
  • 11.  Tertiary treatment add additional cost to the treatment process but produce high quality effluent which can be reuse further for commercial and industrial applications.  Treated water can be reuse for the irrigation of a golf course, green way or park, construction work, industrial process, etc. If it is sufficiently clean, it can also be used for groundwater recharge.  Treated water is sometimes disinfected chemically or physically depending upon the discharging location.

  • 13.  Equalization: The raw waste from the main plant is first collected in the equalization tank through screening.The equalization tank is designed for a hydraulic retention time of around 6 hours and is avoided with air grids connected to air blowers for maintaining the solids is suspension  Effluent Mixer Flocculation Tank & Clarifier: The equlized waste is then pumped into the flask mixer compartment of flash mixer & flocculation tank where coagulant is dosed and polymer in the flocculation compartment to aid the process of settling. The overflow from the flocculation compartment is taken into the clarifier for removal of suspended solids and BOD/COD.The overflow from the clarifier is taken for further treatment while the underflow is taken for sludge compartment.
  • 14.  Biological Treatment: The neutralized effluent will this the treated through the Bio Tower with aeration tank and clarifier. The liquid overflow from the Lamella clarifier is taken to the chlorination tank. The sludge underflow from the Lamella clarifier is partially returnedto the inlet of the aeration tank for maintaining the desired level. The excess sludge is treated through a basket type centrifuge.  Filtration: Chlorinated water will be passed through a Multigrade Sand Filter for further reduction of suspended solids to less then 20 ppm and then passed through a activated carbon filter for the polishing of BOD, COD values.
  • 15.  Sludge Treatment: The under flow from the clarifier and the secondary clarifier having a sludge consistency of around 1- 1.5% is pumped into the centrifuge for dewatering. The dewatered sludge is then disposed off suitably while the concentrate is taken back to the equalization tank
