Water quality analysis - Analysis of discharge water

We maintain high precision through the implementation of internal and external precision management!

In the case of discharged water, standards for discharge have been established under the Water Pollution Prevention Act and the Sewerage Act to protect the environment of rivers, lakes, and marine areas. Naito Environmental Management Co., Ltd. provides support from proposing analyses tailored to customer needs, reporting results, to aftercare, while maintaining high accuracy through internal and external precision management. We have also established a system capable of analyzing over 100 samples per day, allowing for speedy reporting of analysis results. ○ Analysis of items under the Water Pollution Prevention Act and discharge standards ○ Analysis of items under the Sewerage Act and exclusion standards We can accommodate each of these! In addition to treated water, we also conduct analyses of raw water and process wastewater.
