Optimizing organic wastewater treatment through inflow water quality management

Wastewater containing organic matter at semiconductor plants can vary greatly in its concentration depending on the status of production and other factors. It was necessary to operate with an adequate margin in order to ensure appropriate wastewater treatment even if the concentration should change. This increased electricity and other costs necessary for wastewater treatment.

・The water quality of raw water is invisible, so it was necessary to operate with an adequate margin to ensure water quality post-treatment.

HORIBA contributes to the optimization of operations with an extensive lineup of water quality meters, including TOC meters that can measure inflow water (raw water) with high resolution capability thorough use of the 1200°C combustion oxidation method and ammonia nitrogen meters with excellent serviceability.
