Development of Miragrace:

We have been putting much effort into developing a coagulant agent (which compared with other existing coagulant agents, has high separation and coagulation capacity and shorter processing time) for various water qualities.

Oxygen water development efforts:

Water resulting from wastewater processing is emitted as oxygen water that contains an abundance of active oxygen, which reduces the sea area that is oxygen impoverished and leads to broad range of environmental conservation.

Solidification of sludge after coagulation: The coagulated sludge is solidified simply by means of compression making this a low cost and low energy coagulation and solidification process. We are striving to adapt this process for large scale operations.


zero emission is an approach towards building a "recycling society" by working to get the absolute closest to zero emissions at every stage from production, through to distribution, consumption, and disposal.

At YSD, we are conducting research development aimed at making the zero emission process more efficient through processes that wipe out the contamination caused by industrial wastewater and domestic wastewater.

What is oxygen water
Oxygen water contains an abundance of active oxygen and it contributes to improving the environment of the impoverished oxygen sea area for example.
By reducing the sea area of the impoverished oxygen sea, it broadens the area in which plants can exist and this reduces CO2 and leads to the prevention of global warming.
