Our Value Proposition

Technological Capabilities Developed Over More Than 80 Years
Our core technology—separation and purification—is centered on separating and removing unwanted components and purifying valuable components to high purity. We have repeatedly developed our technologies starting from customer needs across a wide range of water applications, and have refined our own proprietary applied technologies. In ultra-high-purity domains such as ultrapure water, we have also developed in-house analytical technologies that verify water quality, supporting both quality and reliability.Our core technology—separation and purification—is centered on separating and removing unwanted components and purifying valuable components to high purity.

Maximizing Value Through Advanced Technology and Supply Capability
We are advancing technologies that balance stable supply with reduced environmental impact, including the development of 100% domestically produced electrodeionization (EDI) systems and solvent recovery systems for lithium-ion batteries. In preparation for longer material lead times and labor shortages, we are also expanding our overseas locations, introducing construction robots, and strengthening our supply chain through design automation and faster delivery.
Products and Services

Pure and Ultrapure Water Systems
We produce JIS A4-compliant pure water in which impurities have been thoroughly removed with the use of advanced separation and purification technologies, such as our ion-exchange resin method. We support quality improvements and productivity in fields such as semiconductors and pharmaceuticals that demand high-level water quality.

Water Treatment Facilities
Reducing environmental impacts and achieving legal compliance by designing treatment processes optimized for specific wastewater characteristics. We also help with reusable materials recovery and water recycling to support sustainable business operations.

Other Technologies and Services
We leverage the water treatment technologies we have developed over many years along with our extensive engineering achievements to meet a diverse range of needs. Our comprehensive services cover everything from design and installation to operation and maintenance, helping to solve our customers' challenges.
