The Ministry of Environment, Forest and Environmental Change has advised the updated CPCB Guidelines for Common Effluent Treatment Plants (CETPs) working at different industrial clusters in the country. The primary point of the revised standards is to minimize water contamination. These standards were finalized after extensive consultations with industries and different partners and detailed deliberations with the Central Pollution Control Board (CPCB). The changed norms were notified on January 1, 2016. The changed norms will help fundamentally work on the performance of CETPs through the implementation of design inlet quality, resolving the issues of coastal pollution because of industrial discharges, and keeping a close watch on the effect of the release of industrial effluent on soil and groundwater quality.

The Guidelines given for CETP by CPCB Guidelines for Common Effluent Treatment Plants are as per the following:

CPCB Guidelines for Common Effluent Treatment Plants

1- The Centre has advised the revised standards for Common Effluent Treatment Plants (CETPs) working at different industrial groups in the country with an aim to minimize water contamination.

2- The Environment Ministry notified the norms which were concluded after broad counsel with industries and other partners and point-by-point thoughts with the Central Pollution Control Board (CPCB).

3- “The Environment Ministry has notified the revised standards for Common Effluent Treatment Plants (CETPs) working at different industrial groups in the country. The primary point of the revised standards is to minimize water contamination,” an official statement said today, adding that the revised standards were notified on January 1.

4- The revised standards will help in essentially working on the performance of CETPs through the implementation of design inlet quality, addressing the issues of coastal contamination because of industrial discharges.

5- It will also help in further improving the CETP’s performance by close watch on the effect of the discharge of industrial effluent on soil and groundwater quality.

6- Under the revised standards, an provision of soil and groundwater quality checking two times per year (pre-and post-monsoon) has been introduced.

7- This has been introduced with a concentrate on the effect of removal of treated effluent on land, in case of the method of removal is ‘on land for irrigation’ and the monitoring will be done by the separate CETP management.

8- “The method of ‘Discharge into the ocean’ (marine outfalls) giving extremely high dilution will qualify all requirements for a relaxed maximum permissible concentration of Chemical Oxygen Demand (COD).

9- “The maximum permissible concentration of Fixed Dissolved Solids (FDS) by constituent units to CETP has been determined as far as maximum admissible contribution value,” the statement added.

10- Status report by the Central Pollution Control Board (CPCB) consistent with the National Green Court order May 21, 2020, in Original Application No. 593/2017 (Paryavaran Suraksha Samiti and Others Vs Union of India and Others) with Original Application No. 148/2016 (Mahesh Chandra Saxena Vs South Delhi Municipal Corporation and Others).

11- The report of September 16, 2020, contained the state-wise consistency status of all industries generating trade effluent and requiring effluent treatment plants (ETP) – as reported by the state pollution control board (SPCB)/pollution control committee (PCC). According to the information got from SPCBs/PCCs:

  • Out of a total 64,484 number of industries requiring ETPs, 62,653 industries are working with functional ETPs and 1,831 industries are working without ETPs.
  • 61,530 industries are complying with environmental norms and 1,123 industries are noncomplying.
  • There are a complete 191 CETPs, out of which 129 CETPs are agreeing with environmental standards and 62 CETPs are non-complying.
  • There is a total of 15,730 STPs (including municipal and other than municipal (non-municipal/independent) STPs), out of which, 15,200 STPs are agreeing with environmental guidelines and 530 STPs are non-complying.
  • There are 84 CETPs in the construction/proposal stage, whereas, for STPs, 1,081 tasks (municipal and non-municipal) are under the construction/proposal stage.

The report also contained an assessment of the effect of the lockdown on the water quality of major rivers. During the pre-lockdown period  (March 2020), SPCBs gathered samples from 388 locations through 366 samples from the checking locations during lockdown (April 2020) from 19 major rivers, and collected samples were analyzed for Primary Water Quality Measures for Washing Water Quality Standards notified under the Environment (Protection) Rules, 1986.

Reverse osmosis (RO) produces clean, great-tasting water and is widely regarded as one of the most efficient water filtration techniques. Numerous uses for RO systems exist, such as faucets, whole-house, aquariums, and restaurant filtration. Whatever the initial quality of your water, there is probably an RO system that will work for you.

Reverse osmosis: What is it?

When pressure pushes water through a semipermeable membrane, reverse osmosis eliminates pollutants from unfiltered water, or feed water. To produce clean drinking water, water flows from the more concentrated side of the RO membrane—which has more impurities—to the less concentrated side—which has fewer contaminants. The permeate is the name for the produced fresh water. Waste or brine is the term for leftover concentrated water.

Small pores in a semipermeable membrane allow for the passage of water molecules but impede the passage of pollutants. Osmosis involves the concentration of water as it moves through the membrane to achieve equilibrium on both sides. However, reverse osmosis prevents pollutants from passing through the membrane’s less concentrated side.

Let’s use what we now know about reverse osmosis to analyze a real operational plant. 

The entire reverse osmosis procedure, including the pretreatment and post-treatment that are typically necessary for heavily contaminated water, is described as follows:

  1. Pre-chlorination dosing system:

The media filter will be able to filter the majority of it if the supply water is contaminated or includes traces of heavy metals. It is strongly advised to dose some chlorine to convert the dissolved heavy metals to physical form.

  1. Tank for storing raw water:

Most reverse osmosis systems begin with a sizable tank that holds the polluted water, while some RO Systems can draw water directly from a well or pipe feed. Having a large storage tank for your intake water is an easy approach to ensure that your pump lasts as long as possible. Not having enough feed water can harm a pump.

  1. Feed Water Pump:

The treatment system receives its initial pressure from a commercial or industrial pump. The RO membranes and any pretreatment are often passed through this motor’s sufficient water pressure, but if they aren’t, a booster pump may be required later on.

  1. Media or Multi-Layer Filter:

Even while we hate to acknowledge it, some items can’t be purified by membranes. Reverse osmosis is unable to remove particles that dissolve too well in water, such as nitrates, a frequent pollutant present in fertilizers and animal manure. Reverse osmosis typically doesn’t work to eliminate things like bad taste and odor. Media that especially targets the items your RO system can’t catch can be put in a multi-layer filter. A multi-layer filter is necessary if these pollutants are to be removed.

  1. Filter with activated carbon:

To eliminate organic contaminants, unpleasant tastes and odors, and chlorine from the water, activated carbon filters are a suitable option.

  1. Chemical dosing system for anti-scalant:

We employ anti-scalant dosing systems to provide our anti-scalant RO chemical, which aids in preventing membrane fouling.

  1. System for Reverse Osmosis:

We have our reverse osmosis system at last. A booster pump will normally be required right before this phase, if at all. The reverse osmosis system can generate a significant amount of waste and up to one million gallons of product water per day from a continuous inflow. Although it can typically be poured down the drain, check with your local water authority to see whether special handling is required.

  1. Storage tank for product water

The reverse osmosis system’s permeate often drains into a sizable tank where it is stored until needed. If it didn’t, it would be necessary for the system to be on in order to have access to fresh water, which is sometimes problematic. In addition to being utilized in many of the typical industries or applications, an RO system may also be used to pump water straight into a well or aquifer for recharge.

  1. System for Post-Chlorination Dosing:

It is strongly advised to inject some chlorine into the permeate water if it will be kept for more than a day in order to keep it clean and free of contaminants.

  1. Water Pump:

The permeate water is repressurized by this pump until it is no longer usable. This is chosen based on the required head and overall distance to travel. The permeate water must not be contaminated, hence stainless steel must be chosen for this pump.

  1. UV Sterilizer for product water:

The UV sterilizer is used as the last line of defense against infection after the storage tank. Most of the time, we either employ UV sterilization or post chlorination as a disinfection agent.

A healthy ecosystem depends on water because it includes essential substances, which support the development and survival of living things. Water becomes contaminated with hazardous substances as a result of improper use, brought on by growing population and industrial expansion. As more and more wastewater is combined throughout the process, sewage is created.


Netsol Water Solutions is one of the leading and reputable manufacturers of sewage treatment plants in India. You can rely on us if you’re seeking for a reputable STP Manufacturer. We offer our special quality and crafted sewage treatment plants to meet the needs of many sectors, including residential, commercial and industrial.


What kinds of businesses require a sewage treatment facility?


A sewage treatment plant is required for any industry that produces sewage water. Among others, this pertains to the textile, chemical, distillery, metals, paper, and pulp industries.


Characterizing the sewage, ascertaining the influence on receiving streams and land, and identifying the long-term transformation, all decide the objectives of treatment for different industries and commercial places, after which an appropriate treatment solution is designed.


Important considerations when purchasing the right sewage treatment plant


  • Calculate the user population


We must always take our family size into account when purchasing a sewage treatment system, for our home. And, if we’re buying it for a business or industrial building, we should consider how many people will be using it—both employees and customers.


Without knowing how many consumers the plant will serve, we always run the risk of spending money and time on insufficient supplies. We must make sure that our STPs can hold enough water to be used.


  • Know the type of soil


It’s crucial to determine the type of soil before moving somewhere fresh. We must learn to distinguish between dry and moist soil, as well as about the soil’s texture and other features. This enables us to choose the proper sewage treatment facility for installation.

Many plants are only compatible with certain types of soil and may not grow well in others. Therefore, it makes sense to spend money on a sewage treatment plant that works effectively, in any type of soil.


  • Pay attention to variations in hydraulic load


Sewage treatment plant installation on-site can see little to a lot of foot activity. As an alternative, one can have a plant in a place where families go for a vacation, and it might not be working for months.


After a few months of use, the system might not be able to handle a rapid change in load. To use appropriate hydraulic load systems, it helps to consult a qualified business that supplies these sewage treatment systems.


What to look for in a sewage treatment plants reputable manufacturer?


The following points are for you if you have questions about, the qualities of the sewage treatment plant manufacturer. These are listed below:


  • The sewage treatment facilities ought to be self-sufficient


The reuse of water for flushing, gardening and other similar uses is made possible by the treated water. It improves self-sufficiency to reduce water waste and guarantee optimal water use.


  • STPs produced by reputed manufacturers have to have the ability to reduce waste


As one of the top manufacturers of residential and commercial STPs, Netsol Water Solutions provide a sophisticated selection brimming with first-rate features.


For improved environmental protection, it purifies the water and lessens the waste that is released into the environment.


  • Production of Fertilizer


The sludge collected during the sewage treatment process contains a variety of biodegradable materials that, after being dried using the “sludge-drying” method, can be utilized as organic fertilizer.






In order to prevent the water crisis, treating and recycling wastewater is crucial. Water recycling and reuse are made possible by cutting edge technologies. Sewage water recycling is also required by laws and regulations all around the nation.


Are you still confused about the selection of STP manufacturers?


From the investigation of the sewage, to the design and construction of the sewage treatment plants, and to the installation and commissioning, each stage is handled internally by our expert team at Netsol. We also offer routine maintenance and health checks of STPs installed by us.

The Process

Primary Treatment- The wastewater is made to pass through a chamber where bar defenses filter out the floating patches. The performing water is also collected in a collection tank.
Aeration- The water collected is also aerated through air cracker
. The performing water is also transferred to a neutralisation tank.
Neutralisation- This process involves the adaptation of the pH value of wastewater between 6- 7 in a neutralisation tank.
Flocculation and Coagulation- Flocculating agent like Alum is added to the effluent to flocculate the suspended material. And, Polyelectrolyte result is added to congeal the suspended solids in the form of sludge at the bottom of the tank. The performing result is also added to a bioreactor tank.
Biological declination- In the bioreactor tank, nutrients are added for breaking down the organic matter present in the effluent. The sludge is also insulated from the settling tank and the water is filtered through an actuated carbon sludge.
Filtration– The treated wastewater is also made to pass through an actuated carbon sludge to remove the colouring material.
