JOHKASOU FOR DOMESTIC WASTEWATER TREATMENT – A COMPACT AND EFFICIENT SOLUTION
What is Johkasou?
Trong As environmental protection regulations become increasingly stringent, treating domestic wastewater before discharge has become a mandatory requirement for residential areas, restaurants, hotels, schools, and small-to-medium-sized facilities. Among the various wastewater treatment technologies available today, Johkasou is recognized as an advanced, compact, and highly efficient solution.
Johkasou (also known as Jokaso) is a domestic wastewater treatment technology originating from Japan. The system is designed as a packaged treatment unit that integrates multiple treatment processes within a single tank, effectively removing organic pollutants, suspended solids, and pathogenic microorganisms before the treated effluent is discharged into the environment.
Operating Principle of the Johkasou System
The Johkasou system operates through a combination of aerobic biological treatment and sedimentation processes within a fully integrated treatment unit.
The basic treatment process consists of the following stages:

Key Advantages of Johkasou Technology
Compact Design: The entire treatment process is integrated into a single Composite or FRP (Fiber Reinforced Plastic) tank, significantly reducing installation space requirements compared to conventional wastewater treatment systems.
High Treatment Efficiency: The system efectively removes key wastewater pollutants, including:
- Biochemical Oxygen Demand (BOD)
- Chemical Oxygen Demand (COD)
- Total Suspended Solids (TSS)
- Ammonium Nitrogen (NH₄⁺-N)
- Total Coliforms
Depending on the system design and project requirements, the treated effluent can comply with applicable wastewater discharge standards.
Easy Installation: Johkasou systems are manufactured as prefabricated modular units, minimizing construction time and enabling rapid commissioning.
Low Operating Cost: By utilizing naturally occurring microorganisms and simple mechanical equipment, the system requires relatively low energy consumption and maintenance costs.
Stable Operation: The system can effectively accommodate fluctuations in wastewater flow rates, making it suitable for both residential and commercial applications.
Applications of Johkasou in Domestic Wastewater Treatment
Johkasou technology is widely applied in:
- Residential houses
- Villas
- Residential communities
- Small-scale apartment buildings
- Schools
- Hospitals
- Hotels and resorts
- Restaurants
- Tourist accommodations
- Highway rest stops
- Office buildings and commercial facilities
In particular, Johkasou is an ideal solution for areas without access to centralized sewerage and wastewater collection systems.

Development Trend of Johkasou Technology in Vietnam
With the rapid growth of urban developments, resorts, and decentralized infrastructure projects, the demand for compact and efficient wastewater treatment solutions continues to increase. Johkasou is considered one of the most suitable technologies for supporting green and sustainable development due to its small footprint, low operating costs, and reliable effluent quality.
Many local authorities are also encouraging the adoption of decentralized wastewater treatment systems to reduce pressure on centralized sewerage infrastructure while enhancing environmental protection performance.
Johkasou is a modern, compact, and efficient domestic wastewater treatment solution suitable for a wide range of applications, from individual households to hotels, resorts, and residential communities.
With its stable treatment performance, low operating costs, and rapid installation, Johkasou technology is becoming an increasingly preferred choice among project developers for new construction projects.
Investing in a Johkasou system not only ensures compliance with environmental regulations but also contributes to the development of green buildings and sustainable infrastructure for the future.
