Environmentally-Friendly Automated Total Nitrogen/Total Phosphorus Analyzer TPNA-300

*Manager of Engineering Department, HORIBA Advanced Techno Co.,Ltd.

For the purpose of global environment conservation, the Japan's Fifth Water Quality Total Pollutant Load Control Regulation has made it mandatory to measure the water pollution loads (multiplying concentration by drainage volume) of total nitrogen and total phosphorus in wastewater from business premises. In response to this regulation, HORIBA developed the Automated Total Nitrogen/Total Phosphorus Analyzer that has helped effect a great reduction in environmental loads. We have improved our conventional ultraviolet radiation oxidative dissolution method further, and through reducing the quantity of measurement samples, we achieved the reduction of costs in management and maintenance for materials such as reaction reagents (a reduction of up to 10 %). In addition, HORIBA has incorporated a lot of its unique technologies adopting a dissolution/measurement cell integrated architecture. This concept has gained the support of many users, and 1000 or more units are currently working in their fields playing their part in water pollution monitoring.
