Water and Wastewater Analysis Service and R&D
We initially obtained ISO/IEC Certificate No. 17025 in June, 2009 and updated certificate No. 17025/2017 has been issued in November, 2019.
We also certified with 62 parameters, including 58 parameters for chemical analysis, 4 parameters for biological analysis. We are confident that our analysis work is highly reliable.

R＆D
In our laboratory, in order to establish the optimum treatment method according to the characteristic of water and wastewater, we can provide customers with a well-founded and befitting design by conducting treatment tests with a full range of test equipment.
In addition, we are also engaged in technological development activities for advanced treatment plants such as the ultra-high-speed coagulation sedimentation tank; GK-SEPARATOR and the Upflow Anaerobic Sludge Blanket (UASB) method; GK-UASB.
