Meet Alyza!

YSI’s new IQ SensorNet Analyzer for Orthophosphate provides accurate, reliable measurements for process control. The IQ Analyzer features a revolutionary MultiValve that dramatically reduces reagent use and maintenance requirements.

  • Overview

    The Alyza IQ PO4 is an online, cabinet-style analyzer used for continuous monitoring of orthophosphate in a municipal water resource recovery facility. This analyzer is weatherproof and can be deployed anywhere in the wastewater treatment process. Applications include monitoring bio-p removal and monitoring and controlling chemical phosphorus removal. An innovative Multivalve within the analyzer significantly reduces reagent use to 5 µL per measurement decreasing the analyzer’s regular maintenance requirements. The analyzer is available as a single-channel or two-channel instrument. The analyzer is available in one of two measuring ranges: 0.02 to 15.00 mg/L PO₄-P or 0.2 to 50.0 mg/L PO₄-P. The IQ Analyzer can be used as a stand-alone analyzer or be incorporated into an IQ SensorNet network of sensors. The IQ Analyzer provides accurate measurements with minimal maintenance requirements.

    IQ Analyzer offers:

    • Reliable, accurate measurements at low measurement concentrations
    • Extremely low reagent consumption, 5 µL per measurement
    • Automatic calibration, 1 or 2 point
    • Automatic cleaning, lowering maintenance requirements
    • Serviceable – safe and easy replacement of reagents, no need for expensive service contracts
    • One or two channel versions available
    • Reliable sample delivery pump built into the cabinet
    • Uses proven Vanadomolybdate (yellow) method of detection
    • Filtration unit allows analyzer to process samples with solids concentrations up to 6,000 mg/L

    Applications include:

    • Monitoring and control of chemical phosphorus removal, reducing dosing chemicals and sludge production
    • Effluent monitoring to ensure compliance
