The STP
Key Features
Key
Challenges
- Meeting stringent effluent discharge standards.
- The BGMEA complex authority required an STP that could effectively treat wastewater to comply with Bangladesh's Department of Environment (DoE) standards for wastewater discharge.
- The project site had very limited space available for the STP installation.
- One of the biggest challenges was to make the water re-usable for gardening, cleaning and car washing.
Exclusive
Features of MBR
- Smaller footprint
-
- Large clarifiers are rendered obsolete, replaced by smaller, rectangular-shaped chambers housing membrane cassettes.
- Higher biomass concentrations within bioreactors allow for the storage of the same total mass of solids in a smaller tank.
- The smaller footprint of the system result in up to a 50% reduction in space requirements compared to traditional methods.
- High-quality effluent, free of bacteria and pathogens
-
- Effluent from the MBR process is devoid of suspended solids and exhibits reduced bacterial and viral content.
- Due to its high quality, minimal disinfection is required before discharge.
- Treated effluent from the MBR process is also suitable for direct feeding into a reverse osmosis (RO) process.
- Higher automation capabilities
-
- The operation of the MBR system can be fully automated, reducing the need for operator intervention compared to conventional treatment plants.
- The MBR process is well-suited for implementation in decentralized sites due to its automation capabilities and minimal need for manual oversight.
Project
Benefits
The successful implementation of the MBR STP at the BGMEA complex has resulted in several significant benefits:
- Reduced environmental impact
- Compliance with regulations
- Sustainable operations
Kingsley’s
Achievement
- Completion of the project within a remarkable timeframe of 1.5 years.
- Achieved outstandingly low COD and BOD outlet values, reflecting exceptional wastewater treatment efficacy.
- Complete absence of coliform detection, indicating the high level of sanitation and disinfection achieved by the project team.
- Implementation of environmentally friendly practices, including grass turfing over the Integrated Sewage Treatment Plant (ISTP) module, enhancing the aesthetic appeal of the project site.
