Quality Control System

For assured quality and safety, we conduct purification tests in our laboratory using actual wastewater and obtain comparative data before and after treatment.

These results are verified by third-party organizations and issued as official water quality measurement certificates.

Quality backed by objective proof is the very reason why IGADEN’s technology is trusted worldwide.
