Turbidity sensor TurbiTech HR – Self-cleaning Solids Meter
The TurbiTech HR turbidity sensor from Partech is specifically designed for use in wastewater treatment systems where high levels of suspended solids are desirable in the aeration phase.
Membrane bioreactors (MBRs) typically operate with MLSS values in the range of 8,000 to 14,000 mg/L. High MLSS concentrations promote several process benefits, including stable operation, complete nitrification, and reduced biosolids production. This reduces the biological volume requirement (and associated footprint) to only 20-30 percent of conventional biological processes.
In addition, the sensor incorporates a self-cleaning mechanism that ensures that the optical surfaces are kept clean at all times, the cleaning system is designed to avoid problems with ragging and does not smear the optical system. The cleaning system ensures that manual intervention on a routine basis is not required. The sensor simply needs to be checked as part of the general cleaning in place. The large optical surface and sample volume combine to ensure that the sensor provides information that is reliable and representative of the solids present in the process. Grease and fat deposits on the sensor area do not prevent the sensor from measuring. This is in contrast to sensors with small optical surfaces.
