For 5 users
Advanced MBBR Technology

Are you looking for a domestic wastewater treatment solution for a villa, household, or small office that meets environmental standards while saving space? The 1 m³ per day integrated Johkasou system from FUDESO is the perfect answer.

I. Product Overview
The product is designed based on Japan’s renowned Johkasou model, an extremely effective on-site wastewater treatment solution. With a capacity of 1 m³ per day, this unit is especially suitable for residential projects, ensuring effluent meets standards before discharge.

II. Breakthrough Technology MBBR Moving Bed Biofilm Reactor

FUDESO’s key differentiation lies in the application of MBBR technology, which combines traditional activated sludge and biofilm processes.

High treatment efficiency. MBBR carriers provide a large surface area for microorganisms to attach, effectively removing organic pollutants such as BOD, COD, and nitrogen.
Space saving. High biomass density allows for a significantly reduced tank size compared to traditional septic systems.
Stable operation. The system has strong resistance to shock loading.
 

III. Delivery Scope

FUDESO provides a complete turnkey solution assembled at the factory, enabling immediate installation and operation.

- Integrated tank shell made from high durability materials, resistant to environmental impacts, with a compact design.
- Internal piping system pre installed according to the technological design.
- MBBR carriers pre filled in the treatment chamber at standard density.
- Air blower placed externally, includes one high quality blower to supply sufficient oxygen for stable biological activity.
- Careful export packaging. Tanks are secured on pallets and firmly loaded into containers to minimize transport risks and facilitate unloading.
- Documentation and procedures are quick and simple, meeting diverse customer requirements. Includes Certificate of Origin CO Form D for import tax benefits along with full - documentation such as packing list, user manual, quality certificates, factory certificate CQ, water test reports, bill of lading, and CO CQ for imported equipment.

V. Premium Technical Specifications
FUDESO uses materials and equipment from reputable brands to ensure a project lifespan of several decades.

FRP composite tank made from fiberglass reinforced plastic with steel supports. The structure is carefully calculated, suitable for underground installation, chemically resistant, and leak proof.
Fuji Mac air blower from Japan with ultra quiet operation comparable to aquarium aeration and high durability.
MBBR carriers made from HDPE from China with large surface area and lifespan up to 50 years, requiring no replacement.
Anoxic carriers made from PP from Vietnam with spherical design optimized for nitrogen removal.
Piping system uses Tien Phong plastic Class 3 with SUS304 stainless steel supports for corrosion resistance.
 

VI. Smart Treatment Process

Wastewater is treated through a closed loop, biologically optimized process.

Sludge chamber for gravity settling of coarse solids such as waste, paper, and sand to prevent downstream clogging.
Anoxic chamber uses spherical carriers and coarse aeration for mixing, maintaining dissolved oxygen below 1 mg per liter for effective nitrogen removal.
Aerobic chamber using MBBR technology, an improved version of the traditional aerotank, where biofilm on HDPE carriers removes organic pollutants.
Sedimentation and filtration where biomass settles and water passes through a filter to remove floating sludge.
Air lift recirculation automatically returns nitrate rich water and sludge to the anoxic chamber.
Disinfection stage eliminates pathogens before discharge into the environment.
