Key
Challenges

  1. Meeting stringent effluent discharge standards.
  2. The IUB authority required an STP that could effectively treat sewage wastewater to comply with Bangladesh's Department of Environment (DoE) standards for sewage wastewater discharge.
  3. The project site had very limited space available for the STP installation.
  4. One of the biggest challenges was to make the water re-usable for gardening, cleaning and car washing.

Solutions

KESC implemented an Anaerobic-Anoxic-Oxidation (AAO) technology based STP to address the challenges. The reasons of choosing AAO are the following-

  • AAO is a proven and advanced wastewater treatment process that combines biological treatment with anaerobic digestion to produce high-quality effluent. (Solution for problem no. 1 & 2)
  • In contrast to conventional Activated Sludge Process (ASP), AAO technology ensures remarkable space efficiency owing to its cutting-edge features and streamlined design. Also, KESC provided integrated sewage treatment module in order to save space and to reduce civil works’ cost. (Solution for problem no. 3)
  • AAO serves high quality treatment, so minimal disinfection is needed. Even then, UV sterilizer was introduced to reduce any harmful substances. (Solution for problem no. 4)

Kingsley provided its visionary solution by choosing Integrated Sewage Treatment Plant, keeping in mind the client’s requirement and environmental safety.

 

Main Characteristics of Integrated Sewage Treatment Plant

  • Long Lifetime
  • Good Effect of Pollution Removal
  • Less Production of Sludge
  • Good Deodorizing Effect & Low Noise

Exclusive Features of
AAO (Anaerobic-Anoxic-Oxidation)

  1. Cost Effective
    • Requires a lower initial investment. The main expense is construction, with some equipment like diffusers, pumps, and mixers.
  1. High-Quality Effluent
    • Compared to conventional activated sludge (CAS), this system utilizes anaerobic and anoxic microorganisms for treatment, resulting in less sludge generation.
  1. Compliant Discharge
    • The treated water meets the standards set by Bangladesh Department of Environment.
  1. Energy-Efficient
    • Lower power consumption compared to Conventional Activated Sludge.
  1. Easy operation
    • Requires minimal automation and features reliable equipment operation and mature treatment technology.

Project
Benefits

The successful implementation of the AAO STP at IUB has resulted in several significant benefits:

  • Reduced environmental impact
  • Compliance with regulations
  • Sustainable operations

Kingsley’s
Achievement

  • 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.

Operating
Cost

Our Sewage Treatment Plant (STP) is cost-effective due to its chemical-free design. Electricity is the primary expense. The operating cost of this STP is-

  • 5~7.5 Tk/m3 (0.0065~0.0075 Tk/liter)

Conclusion

The IUB Sewage Treatment Plant project is a successful example of AAO technology's application in treating sewage wastewater. KESC's expertise in design, construction, and commissioning ensured the project's timely completion and successful operation. The plant plays a vital role in protecting the environment and promoting sustainable practices.
