Sludge in waste water.  Perfect for Olpas measurement.

True-TSS &
True-MLSS

In wastewater treatment the real, true, values of the Total Suspended Solids (TSS), Mixed Liquor Suspended Solids (MLSS) or activated sludge concentration are key parameters for process control.

Due to the nature of the OLPAS technology using ultrasound backscattering, an intrinsic measurement of the solids concentration is obtained. The ultrasound pulse propagates in the fluid and the resulting backscattering echo is a representative fingerprint of the suspension concentration. 


Ultrasound backscattering is independent of flow conditions, temperature or colour of the medium.

 

Fouling resistance of the Olpas backscattering sensors is far superior to competing technologies.
