Sewage Treatment refers to the process of removing contaminants, micro-organisms and other types of waste products from wastewater primarily from households, hotels, and industrial wastewater. Raw sewage is water that originates from toilets, sinks, showers, baths, kitchens, laundry, etc. The sewage treatment includes physical, chemical, and biological processes to produce environmentally safe treated wastewater to reduce fresh water consumption.

The sewage treatment plant process includes sewage treatment on primary, Secondary, or biological and tertiary treatment processes to improve the quality of wastewater suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution. Innovative technology is used in our sewage treatment facility to clean wastewater of toxins and make it safe for reuse and the environment. The facility has a three-stage procedure to get rid of sediments, germs, and nutrients, producing an effluent that satisfies all legal requirements. Primary clarification, the initial stage of treatment, eliminates big particles and grease from the wastewater. In the second stage, biological treatment, the organic material in the wastewater is broken down by microorganisms. In the third stage, disinfection, any remaining bacteria are eliminated by using chlorine or ultraviolet light. Our sewage treatment facility is built to be incredibly effective and dependable. It is a cost-effective method for treating wastewater since it is simple to use and maintain.



In the sewage treatment plant, sewage water is first allowed to pass through bar screens or a grit chamber where large solids are removed. Which is followed by aeration/mixing in a tank and then primary sedimentation where suspended solids settle down. Primary treatment involves the addition of a coagulant which helps to remove grits, coarse solids, oil, and grease if present. Effluent from primary treatment consists of unstable organic matter which undergoes secondary treatment where the organic matter in sewage is converted into stable forms through biological activities, resulting in secondary sedimentation. Where common approach like the activated sludge method involves the addition of a mixture of active microorganisms to sewage, followed by aeration and agitation. The aerobic conditions and microbial actions oxidize the organic solids resulting in coagulation, flocculation and settling of solids. Activated sludge produces a clear liquid without foul odour. The effluent then undergoes tertiary treatment such as sand filters and reverse osmosis process to remove the dissolved solids which may be used followed by disinfection by incorporation of UV radiation or chlorination, the treatment scheme depends upon the nature of the sewage and the effluent from secondary treatment.

Frequently Asked Question

What is the purpose of a sewage treatment plant?

The main purpose of a sewage treatment plant is to remove pollutants, such as chemicals, nutrients, and pathogens, from wastewater before it is released into the environment. This helps to prevent the contamination of rivers, lakes, and other water bodies, and also prevent the spread of diseases.

How does a sewage treatment plant work?

STPs typically use a combination of physical, chemical, and biological processes to remove impurities from the water. These processes can include screening, sedimentation, filtration, and the use of microorganisms to break down organic matter. The exact processes used will depend on the type of contaminants present and the desired end product.

What are the different technologies used in sewage treatment plants?

There are many different technologies used in sewage treatment plants, including moving bed bio reactor (MBBR), Membrane Bio Reactor (MBR), Sequential Bio Reactor (SBR), Activated Sludge Process (ASP) & Submerged Aerobic Fixed Film Reactor (SAFF). The specific type of plant used will depend on the local regulations, the characteristics of the sewage, and the desired end product.

What are the by-products of sewage treatment?

The by-products of sewage treatment are a combination of water, sludge and biogas. The water is purified after the treatment process and can be reused for irrigation or industrial process. Sludge is the solid waste produced during the treatment and can be used as a fertilizer. The Biogas can be captured during anaerobic digestion and can be used as a fuel.

What are the advantages of sewage treatment?

The advantages of sewage treatment include the reduction of pollution in rivers and lakes, the conservation of water resources, the recovery of resources such as nutrients and energy, and the reduction of odors.

Are there any maintenance requirements for a sewage treatment plant?

Yes, regular maintenance is necessary to ensure the proper functioning of a sewage treatment plant. This can include regular cleaning and inspections, as well as the replacement of parts and equipment as needed.

How much does it cost to build and operate a sewage treatment plant?

The cost of building and operating a sewage treatment plant will depend on many factors, including the size of the plant, the type of treatment process used, and the location of the plant. It can range from a few thousand dollars for a small, residential plant to several million dollars for a large, industrial plant.
