What is a Sewage Treatment Plant?

A Sewage Treatment Plant is a machine that designed to treat and purify wastewater, domestic sewage before it is released into the environment. The main goal of a sewage treatment plant is to remove contaminants and pollutants from sewage so that the treated water can be safely discharged into rivers, lakes or oceans or reused for various purposes.

The sewage treatment process typically involves several stages:

Primary Treatment: In this stage, large solid particles and debris are removed from the sewage through processes such as screening and sedimentation. This step helps in separating the solids from the liquid portion of the wastewater.

Secondary Treatment: After primary treatment, the liquid portion is subjected to biological processes. Microorganisms are used to break down organic matter and nutrients in the sewage, reducing the levels of pollutants in the water.

Tertiary Treatment: This stage is an additional treatment step to further polish the water quality. It may involve processes like filtration, chemical treatment, and disinfection to remove remaining contaminants, pathogens, and impurities.

The treated wastewater, known as effluent, can be discharged into the environment, meeting regulatory standards for water quality, or it can be reused for non-potable purposes like irrigation, industrial processes, or even indirect potable water supply in some cases.

What is a Sewage Treatment Plant?

A sewage treatment plant is designed to treat and purify wastewater before it is released into the environment. Sewage consists of water used in homes, commercials, and industries that contain various contaminants, including human waste, food particles, chemicals, and other pollutants. The primary goal of a sewage treatment plant is to remove these contaminants and make the water safe to be discharged back into rivers, lakes, or the ocean or to be reused for various undrinkable purposes.

Sewage treatment plants typically involve several stages of treatment:

1: Preliminary Treatment

2: Primary Treatment

3: Secondary Treatment

4: Tertiary Treatment

5- Disinfection

6: Sludge Treatment

Once the sewage treatment process is complete, the treated water, also known as effluent, can be safely released into natural water bodies like rivers or oceans or used for non-drinkable purposes such as irrigation. The treated sludge may be further processed, used as fertilizer, or disposed of in an environmentally responsible manner.

Sewage treatment plants are essential for maintaining public health and preserving the environment by preventing pollution of water bodies and the spread of waterborne diseases. Their design and capacity can vary depending on the population they serve and the specific environmental regulations in place.


The demand for effective sewage treatment and wastewater management in Bangladesh is paramount to safeguarding the environment and public health. The top five sewage treatment plant manufacturers in Bangladesh, namely Netsol Water, Sewage Treatment Plants, Urban STP Plant, Compact STP Plant, and Compact ETP Plant, have made significant contributions to addressing this imperative. Their innovative solutions, unwavering commitment to sustainability, and dedication to the nation’s well-being underscore their pivotal role in Bangladesh’s sewage treatment sector. Through collaborations with these manufacturers, Bangladesh is taking substantial steps toward a cleaner and more sustainable future.

The biggest factor affecting human health and the ecosystem is the untreated direct discharge of sewage into natural resources. Waste produced by residential, commercial, institutional,  and industrial facilities is referred to as sewage. Organic and inorganic pollutants are frequently present in large amounts in sewage. Prior to entering any aquatic body, sewage must be treated. It is crucial to correctly treat sewage before putting it into rivers or any other sources of water because if sewage is allowed to enter them without being treated, it will contaminate them.

Sewage treatment plants come to rescue, to lessen the toxicity of sewage, maintain a safe and healthy environment, and advance human welfare, sewage treatment is essential.

Stages in a sewage treatment plant:

A sewage treatment plant (STP) with three stages—primary/preliminary, secondary, and tertiary—can be designed to treat sewage.

1_Primary Treatment:

In the first stage of treatment, wastewater is sent through a screen to catch any big floating debris. Following this, the water enters a chamber that removes grit ( gravel, Sand, eggshells, seeds, bone fragments, and other things are all considered to be grit). To lessen the amount of heavy deposits in the digester, channels, and conduits, grit removal is required. Primary settling tanks are the next stage. These tanks are often rather big, and the solids fall to the bottom by gravity and are removed as sludge. Oil floats to the surface and is skimmed off in the meanwhile. A 30–40% decrease in the biological oxygen requirement over the course of five days may be anticipated as 50–60% of the suspended solids are eliminated.

2_Secondary Treatment:

The second stage of wastewater treatment is secondary treatment. Oil, grease, and colloidal particles are eliminated during basic treatment. The wastewater is then given a second biological treatment to get rid of any organic debris that is still present.

Local and aquatic bacteria and protozoa that devour biodegradable soluble pollutants including sugar, fat, detergent, and food waste carry out this treatment. These mechanisms are temperature-sensitive, and biological responses accelerate as the temperature rises.

Two distinct treatment steps comprise secondary therapy:

  1. Aerobic Treatment _ Aerobic wastewater treatment is a biological process that breaks down organic debris and removes additional contaminants like nitrogen and phosphorus by using oxygen. Aerobic treatment is typically used in the treatment of sewage.
  2. Anaerobic Treatment­_ Wastewater or other materials are broken down by microorganisms during anaerobic treatment without the help of dissolved oxygen. However, anaerobic bacteria may and will utilise the oxygen present in the system’s supplied oxides as well as the organic matter in the effluent.

3_Tertiary Treatment:

The third step of wastewater treatment, tertiary treatment, is also referred to as an advanced treatment. The nitrogen and phosphorus burden in the water is reduced during tertiary treatment. It involves procedures including electrodialysis, nitrification, denitrification, ion exchange, activated carbon adsorption, and filtering.

The effluent properties following secondary treatment and the kind of water required following treatment determine the tertiary treatment alternatives. For instance, filtration and disinfection are used to treat wastewater if we require drinkable water.


Even while water surrounds 70% of the world, just 2.5% of it is fresh water. On Antarctica and Greenland, 70% of the fresh water is frozen. Only a little more than 1% of fresh water can be used. If we can reuse water for uses other than drinking, such as washing, bathing, and using the toilet, we can reduce the need for fresh water. Therefore, it is crucial to treat every building’s sewage outflow and repurpose treated water for laundry, bathroom cleaning, and floor maintenance.
