Johkasou Sewage Treatment Plant

Johkasou in the Japanese language means, Purification Tank. Johkasou products are domestic wastewater treatment systems or Sewage Treatment Plants.

A ready-to-install STP delivers performance confirming the global discharged norms with a minimum 50% Energy saving compared to conventional plants

The plant can be installed above or below the ground. The treated water can be further used for gardening, flushing, cooling towers etc.

• Long Life Product: Johkasou-STP is a simplified product with High treatment performance and a long life
• Japanese Technology: STP designed in Japan is compact & housed in an FRP tank that can be used in a decentralized manner at any remote location.
• Meet Regulatory Standard: STP plants are designed to meet all output parameters as laid down by the Indian Ministry of Environment, Forest and Climate Change (MoEFCC) and Pollution Control Board (PCB) norms.
• Quick & Minimal Maintenance: Maintenance required is monthly removal of plastics and desludging every six months. Operators are not required for small and mid-size packaged plants.
• High Treatment Performance: STP has been passing strict government inspection and test performance is approved by the Japanese Government with continuous nitrification and denitrification process.

1. Separation Box and Sedimentation Chamber: Sedimentation and separation chambers collect domestic wastewater. It also has a function to separate solid wastes from liquid waste based on their gravity.
2. Anaerobic Filter Chamber: Wastewater then flows into the Anaerobic Media contact chamber from the sedimentation and separation chamber. It contains organic material which is decomposed by anaerobic microorganisms.
3. Moving Bed Chamber: Anaerobic chamber water flows into the moving bed (MBBR) chamber. Organic material containing wastewater is decomposed by an aerobic microorganism and becomes a simpler product.
4. Sedimentation Chamber: The Sedimentation chamber provides a place of settled sludge which is the result of biological processes in the moving bed (MBBR) chamber. The settled sludge will be transferred to the sedimentation and separation chamber.
5. Disinfection Chamber: The disinfectant chamber serves as a place to put chlorine/disinfectant as a sterilization agent for pathogenic microorganisms in the waste processed before being discharged into the environment or sent for further treatment if site conditions desired.
6. Inbuilt Circulation Line: Continuous recirculation from the 2nd sedimentation chamber to the separation and sedimentation chamber with an air lift mechanism is adopted. This ensures the denitrification process and continuous water flowing inside the system with multiple times treatment.

The A-A-A ( Anaerobic , Aerobic , Anaerobic) Process ensures continuous and simultaneous Nitrification and Denitrification process.

Johkasou is capable of meeting the needs for output qualities expected by the government regulatory bodies or as per the application requirements.
