Johkasou is a centralized wastewater treatment technology that actively manages domestic wastewater from sinks, showers, and toilets, along with human waste from flushing toilets. While public sewage systems treat wastewater collectively in metropolitan regions, Johkasou offers a practical alternative in areas under urbanization control, regions with lax regulations, and communities with low population densities. In such cases, it provides a more cost-effective decentralized wastewater treatment system.
Moreover, Kubota Wastewater Treatment Solutions achieve a BOD removal rate of 90% or higher. These plants efficiently handle influent BOD levels of up to 200 mg/L and consistently deliver effluent water with BOD levels at or below 20 mg/L. Unlike purely mechanical systems, Johkasou Treatment Plants rely on microorganisms to break down wastewater. With regular maintenance, operators can ensure healthy living conditions for these microorganisms, which in turn sustain optimal treatment performance.
In addition, Kubota wastewater plants come in a wide range of flow rates, starting at 1.0 m³/day. The available Johkasou plant ranges include:
As mentioned earlier, public sewage systems dominate urban wastewater management. However, Johkasou stands out in semi-urban and rural areas by offering a reliable, cost-effective, and decentralized solution.
Ultimately, the Johkasou system not only addresses the growing need for wastewater management in non-sewered regions but also provides a sustainable solution in an era of population decline. By bridging the gap between centralized sewage systems and isolated communities, Johkasou ensures cleaner environments and healthier living conditions.
An aerobic microbe adsorbed in medium within an aeration tank treats wastewater pollutant using the Moving Bed Carrier Filter Technique. Blower air delivery to the aeration tank provides oxygen to the microorganisms that have been adsorbed in the media and ensures good contact between the media and wastewater, resulting in high-performance treatment. Each medium has a sizable surface area to promote the development of a high population of microorganisms. This system offers small design, steady treatment performance, and low cost of installation.
