Self Cleaning Suspended Solids Sensor The TurbiTechw² LA Sensor has been designed for use in aeration systems monitoring suspended solids also known as mixed liquor suspended solids or activated sludge where solids are typically in the range of 1,500 to 3,500 mg/l. The sensor can also measure Returned Activated Sludge (RAS), Surplus Activated Sludge (SAS) and suspended solids or turbidity. The fully automatic self cleaning system ensures that manual intervention on a routine basis is not required.
The TurbiTechw² LS Sensor is designed to monitor the levels of suspended solids or turbidity typically found in final effluent from municipal and industrial wastewater treatment plants. It is also great at monitoring solids in the intake to both effluent and drinking water treatment processes.
Monitoring of these key parameters requires sensors that are reliable and accurate, the TurbiTechw² LS meets this requirement perfectly. The large optical surfaces and sample volume ensure that the information provided by the sensor is both representative of the process and tolerant of fouling. 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 TurbiTechw² HR Sensor has been specifically designed for use in wastewater treatment systems where high levels of suspended solids are desirable in the aeration phase. Membrane Bio Reactors (MBR) typically run with MLSS values in the region of 8,000 to 14,000 mg/l. High MLSS concentrations promote numerous process benefits, including stable operation, complete nitrification, and reduced biosolids production reducing biological volume requirements (and associated footprint) to only 20-30 percent of conventional biological processes.
