The Johkasou system is a decentralized wastewater treatment technology widely used in Japan. It consists of an underground tank that treats domestic wastewater using a combination of physical, chemical, and biological processes. Johkasou systems are desig

What is Johkasou Tank?

As introduced above, Johkasou originates from Japan, abbreviated as JKS. The exact meaning of this name is understood as a filtration tank.

The Japanese Johkasou wastewater treatment technology is a specialized system for treating domestic wastewater. They can be installed in various areas such as apartment buildings, villas, households, etc. Johkasou can treat all types of wastewater from toilets, bathrooms, kitchens to laundry wastewater.

Structure

The tank material is made of fiberglass reinforced plastic (FRP), which has corrosion resistance and can withstand extremely large forces.

The Johkasou domestic wastewater treatment system is designed with a mechanism that uses aerobic and anaerobic microorganisms. They work to remove BOD, as well as organic and inorganic substances, along with harmful bacteria in the wastewater. This will help ensure that the treated water meets standards, reducing the risk of environmental pollution.

Advantages

Normally, the BOD index of domestic wastewater is 200mg/l, nitrogen 50mg/l, and phosphorus 5mg/l. Depending on the nature and type of JKS, the treated wastewater has a BOD index below 20, 10.5 (mg/l); nitrogen content below 20, 15, 10 (mg/l); and phosphorus below 1 (mg/l).

In addition, the Johkasou tank has many outstanding advantages, including:

• Extremely high wastewater treatment efficiency, with thorough sludge collection.
• Saves space, costs, construction time, and investment.
• Simple, quick installation.
• Extremely high durability over time.
• Environmentally friendly design.

Characteristics of Japanese Wastewater Treatment Technology

The Japanese Johkasou wastewater treatment technology is designed with a unique concept. The Johkasou tank helps purify domestic wastewater by using the properties of microorganisms that can eliminate pollutants.

Moreover, JKS also uses a bacteria filter membrane in a spatial direction to increase the contact surface of waste with microorganisms.

The Johkasou tank is designed in various models. Each model will be used depending on the amount of wastewater that needs to be treated.

• For small scale: Used for models from 5 - 10 people.
• For medium scale: Used for models from 11 - 50 people (usually in sparsely populated areas).
• For large scale: Used for models from 51 people and above (usually in high-rise buildings, urban areas, commercial centers, etc.).

Furthermore, before installing the Japanese wastewater treatment system, it is necessary to consider the characteristics of the wastewater, the quality of the wastewater that needs to be filtered. Because each model will be programmed with different treatment methods and processing techniques.

Applications of Wastewater Treatment Tanks in Japan

The Johkasou wastewater treatment technology in Japan can be installed submerged or floating depending on the ground conditions.

The tank is mainly applied in:

• Areas without wastewater treatment and collection systems.
• Areas with high population density, using raw wastewater for reuse, such as for toilets, watering plants, etc.

Moreover, the Johkasou wastewater treatment infrastructure can be installed in areas such as:

• Infrastructure that has not been built wastewater treatment systems.
• Residential areas, apartment buildings.
• Households.
• Headquarters, branches, offices of organizations, individuals.
• Car wash facilities, motorbike wash facilities.
• Hospitals, clinics, restaurants and hotels, production facilities, operation and other service facilities.

When using the Johkasou tank, ensure that the system can simultaneously filter wastewater from toilets, bathrooms, kitchens, or washing machines.
