Why is Johkasou Technology Superior?
The Japanese government has endorsed and widely implemented Johkasou products throughout Japan, leading to a remarkable 26% of the country's sewage being treated through Johkasou systems.
With over 8 million Johkasous operating in Japan and millions more worldwide, these systems are highly regarded globally.
The Johkasou Act enforces a strict 'Evaluation test' before market release, solidifying their reputation as the best wastewater treatment solution.
How can Treated Wastewater by Johkasou Technology be Reused:
Treated wastewater reuse generally refers to the process of using water for beneficial purposes.
Wastewater recycling helps to preserve aquatic life and biodiversity by reducing polluting discharges into surface water.
Wastewater reuse plays a pivotal role in mitigating water scarcity challenges by providing an alternative source of water for non-potable uses.
By responsibly repurposing treated water, we alleviate pressure on strained freshwater reserves and contribute to a more sustainable water cycle.
