Effluent Treatment Plant (ETP Plant)

ingEffluent Treatment Plant Or (ETP Plant)

The ETP Plant designed to treat the effluent coming from different areas of the plant. The  treatment of different effluents varies with the type of effluent.
Water recycled from effluent coming from various industries using series of operations, i.e.Coagulation, Flocculation, Aeration, And filtration techniques mainly reverse osmosis.”

Effluent 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 turned into treated effluent with the help of Effluent Treatment Plant (ETP Plant)” Sometimes it is also called as Sewage treatment Plant (STP).

The effluent may have high BOD, COD, pH, TSS, TDS and Color depending upon type of plant generating effluent. In ETP Plant we essentially treat all these parameters to make treated  water suitable for end usages.

Process of ETP Plant:-

There are various types ofETP Plant” and their design will vary depending on the quantity and quality of the effluent, “Amount of money available for construction, operation and maintenance”, And the amount of land available. There are three mechanisms for treatment which are: Physical, Chemical and Biological. These mechanisms often  used together in a single ETP Plant.

There are generally four levels of treatment under ETP Plant, as described below:
•    Preliminary: “Removal of large solids such as rags, sticks”, “grit and grease that may result in damage to equipment” or operational problems (Physical).
•    Primary: Removal of floating and settable materials, i.e. suspended solids and organic matter (Physical and Chemical);
•    Secondary: Removal of biodegradable organic matter and suspended solids (Biological and Chemical);
•    Tertiary: Removal of residual suspended solids / dissolved solids (Physical, Chemical and Biological)

What Wapp Offers for ETP Plant?

“There are many options for designing of an ETP Plant”. The type of plant and the various components of the plant will depend on the characteristics of the effluent and treated water characteristic. Most often, physico-chemical treatment will combined with biological treatment. The typical components of such a plant are screening, equalization, and pH control, chemical storage, mixing, flocculation, primary settling, aeration, and secondary settling etc. The physico-chemical treatment always comes before the biological treatment units.

Few common process observations are as follows:

TO MEET DISCHARGE NORMS:Physico-chemical treatment will combined with biological treatment.
TO MEET IRRIGATION WATER QUALITY: –Physico-chemical treatment will combined with biological treatment followed by Pressure sand filter and Acivated carbon filter.
TO MEET BATHING WATER QUALITY: – Physico-chemical treatment will combined with biological treatment followed by Pressure sand filter , Acivated carbon filter, Ozonation And UV.
TO MEET DRINKING WATER QUALITY:- Physico-chemical treatment will combined with biological treatment followed   by filters, Ultrafiltration, Ion exchange and Reverse Osmosis.
ZERO LIQUID DISCHARGE: – Physico-chemical treatment will combined with biological treatment followed by filters, Ultrafiltration, Ion exchange, Reverse Osmosis, Centrifuge And Evaporators.

Capacity & Scheme Wapp offers for ETP Plant:-

WAPP” as a solution provider towards Zero Liquid Discharge Plant (ETP Plant) has acquired an integrated approach to optimize the treatment process. We believes in “WHAT GETS MEASURED, GETS MANAGED”.

In order to design treatment plant(ETP Plant) first of all with our team of textile expertise and consultant, we understand textile industry process and nature of effluent generated. As per effluent nature and reuse water properties requirement we optimize and design our ZLD plant assuring maximum recycle and reuse water of various quality in different process and thus managing cost as per Industry liability.

With the increasing pressure of concerned authorities, zero liquid discharge or the maximum reuse of water required in the textile processing industry.
In general people are able to recycle up to 60% only that too with great difficulty considering the cost involved in setting up an ETP plant to meet the discharge parameters. For recycling further processing needed to, make the water useful for textile processing.

To go beyond 60% recycling of water, lot of efforts requires in plant design which is based on the strength of effluent one getting from the process house.
Processing of all textiles be it of natural, animal or synthetic origin, can classified into three main categories namely preparation, coloring, and finishing. Each main category has different unit operations to performed to make the fiber ready for next process. Function of all the processes whether small, medium or large scale industry is the same, difference lies only in quality, productivity and cost depend upon type of machinery, Technology and other infrastructure process unit equipped with.

To reach to the conclusion that which technology best suited to target our aim for ZLD/95% recovery, detailed study of unit operations of different process involved right from Geiger fabric stage to finished stage Ineeded.
To reduce the pollution load which can be measured in terms of BOD, COD, TOC, TSS, O&G, TDS, Alkalinity, Heavy metals etc.; through investigation needed about the presence of dyes and chemicals in the process house.
After thorough screening of the present raw material used, better substitutes available in the market to tried and the effluent generated will tested to design the plant.

It needs lots of understanding and experimentation on different machined used for different fabrics. It depends a lot on the liquor ratio, type of dyes & auxiliaries, pH, temperature and concentration of chemicals used to get the product of desired quality without compromising with physical properties of fabrics.

Need of hour to take an integrated approach to run power house with due consideration of water recycle and best practice to be adopted to have eco-friendly processing for sustainable growth of industry.


Why only Wapp ?

The untreated “textile wastewater can cause rapid depletion of dissolved oxygen, if it directly discharged into the surface water sources due to its high BOD value. The effluents with high levels of BOD and COD values are highly toxic to biological life. The high alkalinity and traces of chromium which employed in dyes, Adversely affect the aquatic life and also interfere with the biological treatment processes.

The quality of such effluent can analyzed by their physicochemical and biological analysis. Monitoring of the environmental parameters of the effluent would allow having, at any time, a precise idea on performance evaluation of ETP/WTP and if necessary, appropriate measures may undertaken to prevent adverse impact on environment.

We at WAPP with our entire team works delicately to provide complete WASTE WATER SOLUTION with our:

  • Design/Supply/installation/ testing / commissioning of plant
  • O&M /Comprehensive and Non Comprehensive AMC
  • Retrofit of old plants
