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.

Total Suspended Solids

• Factory Calibration
t 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
t 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
t 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.
