Japanese Johkasou technology is an advanced yet user-friendly wastewater treatment system developed in Japan, designed to treat sewage efficiently within a single compact unit. The system works through a series of well-organized stages. First, wastewater enters a chamber where heavier solids settle at the bottom. It then moves into an oxygen-free (anaerobic) zone, where natural microorganisms begin breaking down organic waste. After that, the water flows through specially designed fixed media, which provide a large surface for beneficial bacteria to grow and form a biofilm. This biofilm plays a key role in continuously cleaning the water by removing pollutants such as BOD, COD, and suspended solids in a stable and effective manner.

The next stage is the aerobic treatment process, where air is supplied through an efficient diffusion system to provide oxygen for the microorganisms. This step enhances the breakdown of remaining pollutants and helps convert harmful substances like ammonia into safer forms through a natural process. Because the bacteria are attached to the media (fixed film), they remain stable inside the system, allowing consistent treatment performance even when wastewater flow or quality changes. Finally, in the settling stage, any remaining particles are separated, producing clear and treated water that meets environmental discharge standards.

Built on this proven technology, FujiClean Johkasou systems are carefully engineered to deliver even higher efficiency and reliability. The system uses high-quality fixed bed media and an optimized aeration system to ensure maximum contact between wastewater and microorganisms. FujiClean units are compact, durable, and require minimal maintenance, making them easy to operate over the long term. With its stable performance, low energy consumption, and space-saving design, FujiClean provides a practical and dependable wastewater treatment solution for residential, commercial, and small-scale applications.
