Meet Alyza - YSI’s new IQ SensorNet Analyzer for Ammonium

  • Overview

    The Alyza IQ NH4 is an online, wet-chemistry cabinet analyzer designed for continuously monitoring ammonium in the biological tank and effluent streams of municipal wastewater treatment facilities.

    Alyza IQ NH4 provides accurate, reliable data at low measurement ranges with minimal maintenance requirements or operator intervention. The IQ Analyzer features a revolutionary MultiPort mixing valve that dramatically reduces chemical use and maintenance requirements. In addition, Alyza has both an automatic cleaning and calibration option further reducing service requirements.

    Alyza IQ is weatherproof and can be deployed anywhere in the wastewater treatment process. Applications include monitoring in biological tanks for ammonium-based aeration control and plant effluent locations to ensure compliance. The analyzer is available as a single-channel or two-channel instrument allowing you to sample from two different locations. The Alyza analyzer can be used as a stand-alone analyzer or be connected to a YSI IQ SensorNet network of sensors.

    IQ Analyzer NH4 offers:

    • Reliable, accurate data at low measurement concentrations
    • Extremely low chemical use
    • Automatic or manual 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(s) built into the cabinet
    • Uses Indophenol (blue) method of detection
    • Filtration unit allows analyzer to process samples with solids concentrations up to 6,000 mg/L

    Applications include:

    • Biological tank monitoring for ammonia-based aeration control and/or ensure compliance
    • Effluent monitoring to ensure compliance
