YSI IQ SensorNet ViSolid® Total Suspended Solids Sensor The ViSolid is an optical based TSS (total suspended solids) sensor for the IQ SensorNet process monitoring and control system. In order to get a sufficient degree of nitrification, a sufficient sludge age must be maintained. Sludge age is affected by the amount of sludge wasted and the MLSS (mixed liquor suspended solids) concentration in the aeration tank. Monitoring TSS allows direct calculation of sludge age and optimal control of nitrification, denitrification and bio-P removal. Parameters: Total Suspended Solids Temperature • Factory Calibration The ViSolid sensors are precisely factory calibrated for two different types of sludge (activated and primary). The calibration is extremely stable and there is no need to calibrate on-site. A matrix adjustment is possible as needed. A 1-point or multipoint calibration is possible if sludge size, structure or coloration variations need to be taken into account. • UltraClean Ultrasonic Cleaning The ultrasound source is integrated in the sensor and generates high-frequency vibrations of the optical windows. Ultrasonic cleaning prevents biofouling resulting in maintenance free operation with accurate measurements everytime. • Measurement Principle Utilizes two measurement methods depending on TSS concentrations - either backscatter for higher concentrations or scattered light for lower concentrations. • 2-year Warranty A ViSolid sensor with UltraClean technology remains clean after a 30-day deployment.
