Johkasou Sewage Treatment Plant

‘Johkasou’ in the Japanese language means ‘purification tank.’ Daiki-Axis Japanese Packaged STPs (Johkasou) are made from 100% FRP and provide a combination of aerobic & anaerobic treatment for sewage at a single shot; with the entire treatment housed in a single FRP capsule. This combined purification structure is capable of treating both night soil (black water) and domestic wastewater (greywater). These STPs can also be customised to suit special use, local compliance, and other requirements.

These ready-to-install STPs deliver exceptional performance while adhering to the global discharged norms. They are well-suited for various government, residential, industrial, and commercial establishments. Also, compared to conventional sewage treatment plants, it offers 50% energy-saving which helps save money.

These high-quality products are based on the principles of modern technologies and management systems. They also undergo stringent and structured quality testing processes during the designing and manufacturing stage for various physical integrity and performance parameters.

Johkasou STPs come in modular construction, which ensures that they can be installed in open spaces. They offer robust performance, scalability and comes with rapid deployment capability. It also has a low cost of ownership and is designed to meet the various standards for treated water discharge applicable around the globe. The best part, with the help of our specially trained sales team and sales partners, we can help you configure these products as per your requirements.

Johkasou STP Treatment Process

This single tank structure is a compact system that consists of simple treatment processes. The only electrical component in Johkasou STP is the Air blower, and the treatment process includes:

  • Separation Box and Sedimentation Chamber: Here the wastewater – solids and floating materials – is collected and separated based on their gravity.
  • Anaerobic Filter Chamber: The wastewater – which contains organic material – flows into the Anaerobic Media contact chamber where it is decomposed by anaerobic microorganisms.
  • Moving Bed Chamber: The wastewater from the Anaerobic chamber flows into a moving bed (MBBR) chamber wherein the organic waste is further simplified.
  • Sedimentation Chamber: The settled sludge from the biological process in the moving bed (MBBR) chamber is placed here. This Settled sludge is then transferred to the sedimentation and separation chamber.
  • Disinfection Chamber: Here the waste is further processed and disinfected before being released into the environment or sent for further treatment if need be.
  • Inbuilt Circulation Line: The airlift mechanism is adopted for continuous recirculation from the 2nd sedimentation chamber to the separation and sedimentation chamber. This helps facilitate the denitrification process while ensuring that continuous water flows inside the system offering multiple treatments.
