環境科学研究所 List of Products and Services

We enhance the efficiency of heat exchangers such as temporary generators and air compressors at construction sites. In construction maintenance, there are no limitations on the scale of equipment, and we improve the purification of cooling towers and various heat exchangers, as well as their efficiency. This technology significantly reduces the amount of chemicals used and the frequency of maintenance.

• Sanitary fixtures
• Prime movers, torque converters, hydraulic equipment, generators

We address exhaust gases from large construction machinery, odors from temporary toilets at construction sites, and VOC (volatile organic compounds) odors from construction sites. There are no restrictions on the range or scale of deodorization. In construction maintenance, we have the technology to handle VOCs from large factories, unpleasant odors from livestock complexes, unpleasant odors from rivers, canals, and lakes, exhaust gas odors from main roads, and unpleasant odors from exhaust stacks.

• Sanitary fixtures
• Dam construction
• Airport facilities

As a civil engineering project, in addressing soil contamination caused by chemical substances, this technology does not involve soil recovery, preserves existing buildings, does not use external power sources, and can handle all types of pollutants. There is a track record of reducing fluorinated compounds to below national standards.

• Sanitary fixtures

This is a technology that can resolve significant issues such as algal blooms and sludge in rivers, lakes, and dams in civil engineering. It has a proven track record of purifying first-class rivers and large lakes in the country.

• Sanitary fixtures
• Tunnel construction
• Airport facilities

It is possible to prevent the spoilage of drinking water at construction sites and to decompose wastewater from temporary toilets. In construction maintenance, this technology can also handle the purification of water supply tanks, groundwater, and piping of all sizes.
