Xylem's YSI P 700 IQ Orthophosphate Analyzer can be used as a stand-alone analyzer or in conjunction with other sensors in a IQ SensorNet 2020 XT continuous monitoring and control system. The P 700 measures the amount of orthophosphate throughout the wastewater treatment process and can help determine whether or not it’s been eliminated. The analyzer can run itself continuously for up to eight months without needing a user calibration or reagent changes, Xylem says. Because of its two measuring ranges, the P 700 can be used throughout a wastewater treatment plant to measure orthophosphates (also known as soluble reactive phosphorus and commonly referred to as phosphate): from pre-sedimentation to the biological tanks and to the effluent. It provides continuous data to help improve operational efficiency as well as verification of phosphate elimination.
