Details Of This Project
Unissol Group the main STP manufacturer in Bangladesh, has successfully installed a Johkasou Sewage Treatment Plant (STP) at the Govt. Officer’s Residential Building (CGS Colony), Chittagong. This project has an STP (capacity of 450 m3/day). The modules are made of FRP. There are 12 blowers and a pump for pumping the raw water from the raw water tank. There is send vessel for clearing the treated water. The final treated water is used in gardening.
This project reflects our commitment to providing eco-friendly and effective STP solutions across Bangladesh.
Process Flow of the STP
The Johkasou STP at the Govt. Officer’s Residential Building (CGS Colony), Chittagong follows a systematic treatment process:
- Separation Box: Separate solids in wastewater by gravity and prevent the agitation of the excess sludge in Sedimentation & Separation Chamber by influe
- Separation & Sedimentation Chamber: Separate solid debris or impurities from water in influent and circulated water and store these sediments in the chamber. Accumulated sludge should be desludged from the tank periodically at least once in 6–12 months.
- Anaerobic Chamber: It is filled with filter materials, which separate solids and keep anaerobic microorganisms to decompose organic matter.
- Moving Bed Chamber: It is filled with mesh cylindrical media, which retain aerobic microorganisms to decompose and remove organic matter from wastewater.
- Sedimentation Chamber: In order to obtain clear treated water, separate the excess sludge (suspended solids, SS) by gravity. The settled sludge is constantly returned to the sedimentation & separation chamber by the airlift pump.
- Disinfection Chamber: Disinfect the treated water to discharge to the river or other water bodies.
The entire system operates seamlessly, ensuring effective sewage treatment with minimal environmental impact.

Why STP need for everywhere in Bangladesh?
Sewage Treatment Plants (STP) are very important for Bangladesh to keep the environment clean and safe. With more people and industries growing every day, untreated sewage is causing serious problems. Dirty water from homes and factories often goes into rivers and ponds, making them unsafe for drinking, farming, or fishing. This pollution also harms fish and plants.
STP clean this dirty water, removing harmful things before it goes back into nature. Without proper treatment, sewage can spread diseases like cholera and diarrhea, putting many lives at risk. In crowded cities, STPs help manage waste, prevent bad smells, and stop water from flooding the streets. They also protect our natural surroundings and make sure water stays usable for future generations. As floods and rising sea levels become bigger challenges, STPs are needed to keep communities safe and healthy. Investing in STPs is an investment in a better, cleaner Bangladesh.
Bangladesh’s Urgent Need for Wastewater Treatment Solutions
Bangladesh’s rivers, canals, and groundwater are under severe threat due to untreated wastewater discharge. Rapid urbanization and population growth have intensified sanitation challenges, especially in informal settlements.
Decentralized wastewater treatment solutions like Johkasou STP help by:
- Reducing environmental pollution
- Preventing the spread of waterborne diseases
- Protecting nearby rivers and groundwater sources
- Meeting environmental safety standards
Projects like the Bastuhara Slum STP highlight the importance of immediate action to ensure safe sanitation for all.
A Sustainable Future for Bangladesh
Investing in wastewater treatment isn’t just about cleaning up rivers it’s about building a healthier, more sustainable future for Bangladesh. Taking action today can help preserve the country’s rivers, improve water quality, and protect the livelihoods of millions of people who depend on these waterways. From residential communities to commercial developments and institutions, responsible wastewater management helps reduce pollution and protect the natural resources future generations will need.
