The waste water treatment procedure removes pollutants/contaminants from wastewater or sewage released by various industrial endeavors before it reaches springs or normal water-ways such as river-streams., lakes, estuaries, and seas.So now we discuss what is waste water treatment process?

Since the purest form of water isn’t tracked down in nature in that frame of our mind, (outside compound research centers), any differentiation between clean water & contaminated water relies on the kind & grouping of de-basements unearth/traced down in the water as well as on its planned or ordered utilization. In wide terms, water is supposed to be polluted when it contains an adequate number of pollutants to make it unsuitable for a specific use, like drinking, swimming, or fishing.

In spite of the fact that water quality is impacted by normal circumstances, the word contamination ordinarily suggests human action as the source of contamination. Water contamination, consequently, is caused principally by the seepage of sullied wastewater into surface water or groundwater, and wastewater treatment is a significant component of water contamination control.

The process of treating wastewater includes a nos . of water treatment steps , including chemical , biological , and physical ones . Mucks , effluents , and toxic  elements are successfully expelled from sewage , waste water utilizing the treatment  procedures . Waste water treatment  facilities utilizes the most  advanced technologies.

Various types of wastewater treatment process exists and some of them are as follows:

Effluent Treatment Plants(ETP):

An Effluent Treatment Plant is a wastewater treatment plant where the various treatments of industrial effluents and wastewater are processed. On a broader scale, The Effluent Treatment Plants are used in the industrial sector, such as the pharmaceutical industry where ETP are used to remove the effluents from the heavy large scale drugs.

Sewage Treatment Plants(STP):

Wastewater from sinks, showers, clothes washers, washrooms, and different apparatuses needs to go off to someplace. In the wake of crossing miles of sewer organization, it winds up in sewage treatment establishes whose occupation is to treat and release it.

Sewage Treatment Plants(STPs) gather , treat-process , &  discharge waste-water, providing critical support for environmental health & general well-being .

Common and Combined Effluent Treatment Plants(CETP):

The method of gathering, transporting, managing, and discarding commercial state effluents is known as a common effluent treatment plant(CETP). Domestic sewage and Industrial wastewater from plants are included in the emanation. They lessen the expense of wastewater treatment, increment aggregate treatment, and diminish the cost of land for limited-scope organization focuses.

*Sewage Treatment Plant differs from Effluents Treatment Plant as both are used for the treatment of wastewater but they differs on the ground of implementation STP is used for the treatment of wastewater from domestic households, schools, restaurants etc whereas ETP is for the industrial heavy wastewater.

Water treatment plants is the best provider of water treatment plants.

Let’s  discuss about the different stages that exists in the Wastewater Treatment Process :

  • First Stage–Bar Screening

Bulky objects are expelled from the influent to avoid harming the facility’s pumps , valves , and other machinery.

The hope is that after treatment, the water will be safe to re-enter the environment. Wastewater is defined as any water that has been used in homes, including flushing toilets, washing dishes, or taking a bath, as well as some water from industrial use and storm sewers.

The bio-chemical oxygen demand(BODs) of typical waste water effluent is 200 mg/L , while the treated effluent is expected as to be >30 mg/L as an instance of expected norms/standards. A wastewater plant must adhere to these standards or face harsh penalties .

Screening out large objects that have made their way into the sewer system is the first step in the physical treatment of wastewater because if they aren’t eliminated , they can harm pumps and obstruct water flow. Large objects are typically removed from the influent using a bar screen before being sent to a landfill .

  • Second Stage – Screening

Removal of Large Grit by forced passing influent over or through a grit chamber.

To avoid harming pumps and other equipment downstream (or affecting water flow), fine grit that enters the influent must be removed. This grit entailed to be pulled out of the grit-chamber since they are small-sized to be screened out.  The bulkier grit can be submerged to the chamber’s bottom , thanks to different types of grit chambers(horizontal , aerated , or vortex) , while the water as well as the organic material moves on to the next step in the process. Physical or manual removing & abandoning the grits from the its chamber’s bottom .

  • Third Stage – Primary Clarifier

Primary disintegration of waste water and solid organic matter .

Sludge or organic solid matter are pushed to a digestor or any other location by pumping for processing , drying , & removal after they descends to the lower bottom of the tank. An indispensable sign of how efficaciously the clarifier is operating in proper settling rates. The operator can alter the flow rate into the clarifier to change the settling rates and efficiency.

Following grit removal, the influent enters massive primary clarifiers, which separate out 25% to 50% of the influent’s solids. The cleaner influent can flow via these sizable clarifiers, which are 75 feet in diameter, 712 inches at the sides, and 1012 feet in the center, for instance.

A standard water-flow is vital for the primary clarifying to be very effective. The downstream water quality will suffer if the water flow is too rapid since the sediments won’t have time to fall to the bottom. The up-stream processing is influenced and disturbed if the water flow is too slow.

Sludge, or the solids that settle to the bottom of the clarifier, is routinely pushed away to prevent interference with the separation process. Any remaining water is then dumped, and the sludge is typically used as fertilizer.

  • Fourth Stage – Aeration

To promote the conversion of NH-3 to NO3 and to give oxygen for bacteria to continue to multiply and develop , air is pushed into the aeration tank or basin . Once the nitrate molecules have been transformed to NO3 , the bacteria extract  the oxygen from the nitrate molecules , releasing the nitrogen(N) as N2(nitrogen gas).

  • Fifth Stage– Secondary Clarifier

Pumping treated wastewater through a secondary clarifier enables any lingering organic matter to separate out of the flow of treated water.

As the influent exiting the aeration operation section, it goes into a secondary clarifier , where any sort of even very minute solids(or fines) , like in the primary clarifier , drop to the lower bottom of the tank. The tiny fragments , also called as activated sludge, are initially formed from a living bacteria. To boost the bacterial concentration, aid in their growth, and quicken the breakdown of organic material, some of this activated sludge is reintroduced to the aeration tank. The surplus gets thrown away. The organic content in the water coming out of the secondary clarifier has been greatly reduced, and it should be getting close to the projected effluent standards.

Sixth Stage– Chlorination(Disinfection)

To expel-out any left-over bacteria in the contact-chamber, chlorination is made to be introduce as the technique. It is necessary to analyze the departing effluent for the presence or absence of bacteria and to disinfect the water because the aeration stage increases the concentration of bacteria. This makes sure that bacteria in quantities greater than those allowed won’t be released into the environment. The most prevalent and affordable kind of disinfection is chlorination, but ozone and UV disinfection are also gaining favor. Before chorine is released into the environment, it is crucial to test the free-chlorine levels to make sure they are within permissible ranges .

  • Seventh Stage– Chlorination(Disinfection)

The performance of the plant depends on testing for the right pH level , ammonia , nitrates , phosphates , dissolved oxygen , and residual chlorine levels to comply with the Government permit.

A final experimenting test is carried out to confirm to be assured that the effluent exiting/leaving the plant complies/matches with permit requirements , even though tests are carried out throughout the waste water treatment techniques to guarantee adequate/sufficient water flow , clarity , & aeration. If a treatment plant system doesn’t matches/comply with the permit/allowance of discharge limits , the operator in-charge could be fined penalty and/or imprisoned.

  • Eighth Stage– Effluent Disposal

Clean water is restored in to the environment once it has complied with all permit requirements.

A final experimenting test is carried out to confirm to be assured that the effluent exiting/leaving the plant complies/matches with permit requirements , even though tests are carried out throughout the waste water treatment techniques to guarantee adequate/sufficient water flow , clarity , & aeration. If a treatment plant system doesn’t matches/comply with the permit/allowance of discharge limits , the operator in-charge could be fined penalty and/or imprisoned.

Waste water Treatment Systems are evolving with the technological advancements with the use of many smart tools which can process any operation remotely and instantly as well. ETPs manufacturing is on the rise for them to be installed in most of the industries.

Wastewater produced by a range of production and processing procedures is known as industrial effluent. Industrial wastewater can contain a variety of different components, depending on the business. Along with other components like heavy metals, acids, and alkalis, organic molecules like oils, lipids, alcohols, and flavourings also interact with the water. Now we discuss about Waste Water Treatment Plant Energy Consumption.

Before being discharged to sewage treatment facilities for the general public, the environment, or internal reuse, this type of wastewater must first undergo pretreatment.

Let’s discuss in detail about the energy consumption of wastewater treatment plant.

The urban water system is now more dependent on energy for both transportation and treatment due to the increasing shortage of water. The availability of electricity may prevent metropolitan areas from becoming sustainable, leading to a shortage of water supplies and water pollution. Energy conservation, energy efficiency, and energy substitution have also become universal development principles due to growing climate concerns.

Techniques and data gathering

It has been noted that energy is used up during the treatment process in the forms of electrical, manual, chemical, and mechanical energy. Chemical energy is indirect energy, manual labour is renewable energy, while other types of energy are non-renewable. In terms of kWh/m3 of treated wastewater, each type of energy consumption is calculated.

Primary data have been gathered by field observation, and historical data have been verified through conversations with plant operators. For verification, logbooks and records of purchases and consumptions are also used.

Estimating the amount of electrical energy used

The electrical energy input is calculated by taking into account the total amount of wastewater that has been treated, the electrical load of the pump/motor (kW), and the number of hours (h) that the motor has been running (Eq. 1).

where P is the rated power of the electrical motor in kilo Watts (kW), T is the number of operating hours per day (h/day), and Q is the total flow of wastewater in m3/day. It is expected that the motor efficiency is 80%.

Energy estimation for the fuel

Using Equation 2, mechanical energy (Ef) is calculated in kWh/m3

where D is the quantity of diesel consumed in l/day and 15.64 is the unit energy value of diesel in kWh/l. Mostly, 5 litre of diesel per month are discovered to be consumed for lubricating and maintaining machinery.

Measuring chemical energy

Energy is the substance that is given off or taken in during a chemical process. By calculating the standard enthalpy (heat) of reaction (H) of the chemicals during a reaction, chemical energy can be computed.

Using Equation 3, chemical energy (Ec) is estimated in kWh/m3

Ec=n [ ∑ΔHp−∑ΔHr ] / Q × 0.000278

where n is the number of moles (mol/day), 0.000278 is the conversion factor from KJ to kWh, and Hp and Hr are the enthalpies (heat) of product and reactant production, respectively, in kJ/mol.


It has been projected that the complete treatment procedure will require 0.036 kWh/m3 of fuel energy (diesel). As a result, 1.07 kWh/m3 of treated wastewater is used in total. Compared to the value obtained in a WWTP, which was reported to be 1.69 kWh/m3 omitting manual energy, it is significantly less. Numerous research has solely taken into account electrical energy; hence their findings do not fully represent the energy picture of a treatment process. The amount of electrical energy needed for waste water treatment plants is found to be 0.80 kWh/m3.

In terms of energy planning, there are some conclusions that are important. First, of all the energy types used in the treatment process, electrical energy accounts for the largest share (52%) of total energy consumption. Only roughly half of the total energy use comes from this, though. As a result, other types of energy should be taken into account throughout the energy benchmarking process.

Water is a valuable resource. The majority of the water on Earth is seawater. A little over 2.5% of the planet’s water is freshwater, meaning it doesn’t have any salt or dissolved minerals in it, and two thirds of that amount is frozen in ice caps and glaciers. Only 0.01% of the water on the globe may be used for human consumption. An essential human requirement is access to clean drinking water. Unfortunately, in the poor world, more than one in six individuals still do not have trustworthy access to this priceless resource. When you find the best Wastewater Treatment Plants In India you can aware following things:

India makes up 16% of the global population but just 2.45% of the world’s geographical area and 4% of its water resources. By 2050, the population is projected to surpass 1.5 billion people at its current growth rate of 1.9% annually. Water demand is forecast to rise from 710 BCM (Billion Cubic Meters) in 2010 to over 1180 BCM in 2050, with an almost 2.5-fold increase in both home and industrial water usage predicted. Urbanization in India is putting pressure on local government to provide infrastructure and basic necessities like clean water to consume.

The demand for portable water has increased due to the population’s rapid growth, necessitating the exploration of raw water sources and the development of treatment and distribution systems.

Here we are going to learn about the steps taken in India for the water treatment plants.

According to the Central Pollution Control Board’s most recent assessment, India’s wastewater treatment facilities are only equipped to handle little more than a third of the country’s daily wastewater production. According to the research, India produced 72,368 MLD (million litres per day), while treatment plants installed capacity was only 31,841 MLD (43.9%). 26,869 MLD of this installed capacity was developed and put into use (84 per cent). The actual capacity used was 20,235 MLD, or 75% of the operationalized capacity. In other words, only 20,235 MLD of the total 72,368 MLD of wastewater produced each day is processed.

Skewed distribution

Sixty percent of the nation’s installed treatment capacity is located in five states and union territories: Maharashtra, Gujarat, Uttar Pradesh, Delhi, and Karnataka.

These six states—Madhya Pradesh, Haryana, Punjab, Tamil Nadu, and Rajasthan—along with UTS and five other states account for 86% of the total installed capacity.

There are no wastewater treatment plants in Arunachal Pradesh, Andaman & Nicobar Islands, Lakshadweep, Manipur, Meghalaya, or Nagaland.

There are certain states, like Bihar, that do have a modest amount of Treatment Plants installed. However, they receive a zero for operational performance. In Bihar, sewage production is 2,276 MLD. It currently has a 10 MLD installed capacity and one Treatment Plant. However, that is likewise not working.

Assam produces 809 MLD of wastewater in a same manner. But it lacks even a single functioning treatment facility. The state makes use of septic tanks.

When comparing the overall amount of wastewater produced to that which is actually treated, Chandigarh comes out on top. It produces 188 MLD of waste water and has a 271 MLD operating capacity.


According to government figures, 62.5% of India’s urban wastewater is either not treated at all or just slightly treated. Water pollution, recycling, conservation, reuse, and recharge issues in the nation are made worse by the inadequate infrastructure for wastewater treatment and by poor operational maintenance.

Few states have implemented wastewater management regulations, including Gujarat, Maharashtra, Rajasthan, Chhattisgarh, Karnataka, and Madhya Pradesh. The efforts of a few states to combat water pollution are ineffective in the absence of a comprehensive federal mandate and standard regulations across states to regulate the untreated wastewater pouring into the water bodies. So these are the factors to look when you Find the best Wastewater Treatment Plants In India.
