Self Cleaning High Range Suspended Solids Sensor

TurbiTechw² HR High Range

Specifically designed for use in wastewater treatment systems where high levels of suspended solids are desirable in the aeration phase.

TurbiTechw² LA

DTG6 A LED Display, 24 VDC Source 3-wire Switch Output

Self Cleaning High Range Suspended Solids Sensor

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.

Features

  • Fully Automatic Self Cleaning.
  • Flexible Mounting System.
  • Large Optical Surface.

Benefits

  • Automated Aeration Control.
  • Low Cost of Ownership.


The TurbiTechw² HR sensor is suitable for monitoring solids in higher ranges than the standard LA version of the sensor due to it’s shorter path length.

In addition the sensor incorporates a self cleaning mechanism that ensures 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 should simply be checked as part of general site housekeeping. The large optical surface and sample volume combine to ensure that the sensor is providing information that is reliable and representative of the solids present in the process. Deposits of fats and grease on the sensing area do not prevent the sensor from measuring unlike sensors with small optical surfaces

The TurbiTechw² HR Sensor uses infrared light at 860 nm and operates using the Light Attenuation Principle. The cleaning mechanism uses a polyurethane wiper seal, sealed by 2 Nitrile ‘H’ Rings that finish the cleaning process. The Nitrile seals can be exchanged for Viton if the process media dictates. The cleaning process is automatically initiated by the 7300w² Monitor at a user determined frequency. The cleaning process takes only 90 seconds, which means that the sensor is available for 99.5% of the time with a 6 hourly cleaning cycle.

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 large optical surface and sample volume combine to ensure that the sensor is providing information that is reliable and representative of the solids present in the process. Deposits of fats and grease on the sensing area do not prevent the sensor from measuring unlike sensors with small optical surfaces. In addition, the sensor incorporates a self cleaning mechanism that ensures 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.
