Effluent Treatment Plant (ETP) Manufacturers & Suppliers in Hyderabad


Effluent Treatment Plants (ETP) 

Effluent Treatment Plant or ETP is one type of waste water treatment method which is particularly designed to purify industrial waste water for its reuse and it’s aim is to release safe water to environment from the harmful effect caused by the effluent. Waste water treatment plants will treat effluents coming from various industries. These Plants are widely used in industrial & commercial sectors like Pharmaceutical, Food/Beverage Production, Paper & Textile, Power Plants & Steel Plants, Cement Industries, Hospitals and Oil Refineries.

ETP Technologies 

  ◈ Aerobic Treatment 

  ◈ Anaerobic Treatment  

Effluent Treatment Plant is developed to treat the effluent that is waste water coming from different areas of plant. Water is the main resource used in all types of industries for many processes. But water used in industries in not consumed completely. Furthermore, almost all industries generate waste water from plants which needs proper immediate action. Waste water can pollute environment. So, the treatment of waste water i.e untreated effluent is turned into treated effluent with the help of Effluent Treatment Plant (ETP), so times it is also called as Sewage Treatment Plant (STP). 


Effluent Treatment Plant can be operated in 4 different processes 

Preliminary – Removal of Solids, Oil & Grease 

Primary – Removal of Suspended Solids & Organic Matter 

Secondary – Removal of Biodegradable Organic Matter (BOD)

Tertiary – Removal of Residual Suspended Solids & Dissolved Solids 


A) Preliminary Treatment : Its objective is physical separation of large sized contaminants. For example cloth, paper, plastics, wood logs etc. This level/process include:

Screening: This is the first unit operation that occurs in waste water treatment plants. A screen is a device with uniform openings and its purpose is to remove large floating solids.

Sedimentation: It is a physical water treatment process using gravity to remove suspended solids from water.

Grit Chamber: The wastewater that moves into the grit chamber removes the dense inorganic solids such as gravel, metal   fragments and sand which have made their way into the sewers. Removal of grit can prevent damaging of pumps &     operational difficulties.

Clarifiers: These are tanks built with mechanical means for continuous removal of solids being deposited by sedimentation before biological treatment.


B) Primary Treatment : Its aim is removal of floating and settle able materials such as suspended solids and organic matter. In this treatment both physical and chemical methods are used. It includes:

Flocculation: Flocculation is a physical process and does not involve the neutralization of charge. It involves the addition of  destabilized particles together into large aggregates so that they can be easily separated from the water.

Coagulation: is a process in which coagulants are added for the purpose of rapid settlement of minute solid particles in a liquid into larger mass. It permits particle removal by sedimentation and for filtration.

Neutralization: The main purpose of this process helps in maintaining the pH range of 6-9 to meet the requirements of different processing units in ETP system.

Primary Clarifiers: These are used to slow the velocity of the water to a point where organic solids will settle to the bottom     of the tank and it contain an equipment that is used to remove floating solids and greases from the surface.


C) Secondary Treatment: The objective of this treatment is the further treatment of the effluent from primary treatment to remove the suspended solids and residual organics. In this step biological and chemical processes are involved.

Activated Sludge Process: This is used for treating industrial waste water using air and a biological floc composed of bacteria.

Aerated Lagoons: Is a treatment pond provided with artificial aeration to promote he biological oxidation of waste water.

Trickling Filters: Trickling filters, also known as sprinkling filters, are commonly used for the biological treatment of  domestic sewage and industrial waste water.

Rotating Biological Contactor: It involves allowing the wastewater to come in contact with a biological medium in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment.

D) Tertiary Treatment: The purpose of tertiary treatment is to provide a final treatment stage to raise the effluent quality to the desired level before it is reused, recycled or discharged to the environment.

Chemical Coagulation and sedimentation: It is used to increase the removal of solids from effluent after primary and   secondary treatment.

Filtration: The clarified wastewater is first passed through the adjacent filtration plant which contains large filter blocks to ensure high quality water.

Reverse Osmosis: In this process, pressure is used to force effluent through a membrane that retains contaminants on one side and allows the clean water to pass to the other side.

UV Disinfection: It is considered as an ideal disinfectant for industrial waste water. It leaves no residual disinfectant in theaters by ensuring the water quality. It does not produce any disinfection by products.

Effluent Treatment Plant Design:

The design of ETP depends on quality and quantity of waste water discharged from the different industries and land availability. If the availability of land in your industry is less, then Common Effluent Treatment Plant (CETP) is preferred over Effluent Treatment Plant (ETP).



Operation & Maintenance of ETP: 

Once wastewater treatment plant constructed need to have operation & maintenance through experienced and qualified persons to serve efficient & effective operation of ETP, qualified ETP operator being provided by us to maintain the record of operation and maintains day to day troubleshooting.

The Role Of MBR Technology In Water Treatment Plant .

  Details About MBR Technology Membrane Bioreactor (MBR) Technology is an advanced water and wastewater treatment process that integrates biological treatment with membrane filtration. It combines the benefits of biological degradation (typically through activated sludge or other biological processes) and membrane filtration (such as ultrafiltration or microfiltration) to create an efficient and compact treatment system.   Advantages of MBR Technology High-Quality Effluent: MBR systems consistently produce treated water of high quality. The membrane filtration removes particles and pathogens, reducing the need for secondary treatment and disinfection. The effluent typically meets stringent standards for suspended solids, biological oxygen demand (BOD), chemical oxygen demand (COD), and nutrients. Compact Design: MBR systems require less space compared to conventional treatment systems, as the membrane filtration ...

WHY WASTE WATER TREATMENT IS IMPORTANT?

  Wastewater treatment protects humans and ecosystem Wastewater contains elements toxic to humans and the ecosystem. Wastewater treatment facilities help to purify the water and eliminate situations like what is currently seen in developing countries. Unclean water poses significant health risks, accounting for 1.7 million deaths annually, of which over 90 percent are in developing countries. 2  Several water-related diseases, including cholera and schistosomiasis, remain widespread across many developing countries, where only a very small fraction (in some cases less than 5 percent) of domestic and urban wastewater is treated prior to its release into the environment 3 . Wastewater treatment also protects the ecosystem. Fish and aquatic life require fresh water. When their water environment is laden with wastewater, they cannot survive. If chemicals, such as nitrogen and phosphates, enter streams, rivers or large bodies of water in excessive amounts, it causes excessive...

Sewage Treatment Plant (STP) Manufacturers & Suppliers in Hyderabad

  What is a S ewage T reatment P lant? Sewage treatment plants process and treat wastewater/sewage, breaking it down into a cleaner ‘effluent’ that can be returned back to nature in a safer, eco-friendly form. They help restore groundwater balance, curb diseases and stop degradation and pollution of the environment.  In housing societies, the treated water can be used for non-potable purposes such as gardening, washing cars, construction, irrigation and toilet flushing. Cleaner water would minimize fatalities due to water borne diseases, there’d be less negative environmental impact from water pollution and from a much narrower point of view, no house would have to pay for water tankers, because there’d be abundance of groundwater on macro scales and reusable water at community levels.   STP Technologies:    ◈ MBBR - Moving Bed Bio Reactor    ◈ SBR - Sequential Bio Reactor MBBR: Moving bed biofilm reactor (MBBR) is  a biological...
