Japanese Government Manufacturing Certification

Core Concept of Johkasou

Johkasou system is regulated by the johkasou Act, in which technical standards for its manufacturing, installation, and operation & maintenance including desludging are stipulated. The Act also stipulated a qualification system for johkasou related technicians. In addition, Johkasou act stipulates each johkasou product to pass the performance evaluation test before putting the product in the market. Furthermore, in Japan the sludge generated from johkasou is appropriately treated at night soil treatment facility before used as fertiliser or industrial fuel.

This way Johkasou can play the role of a wastewater treatment facility to become a system that integrates the technology and its management, which is useful for both mankind and environment.

Core Concept of Johkasou is to treat domestic waste water locally and Reuse it locally, which is very appropriate for India in current circumstances.
