AUTOMATION IN SLUDGE DEWATERING BY NOVEL ON-LINE CHARACTERISATION OF FLOCCULATION

BORMANN H. / SCHROEDER C. / SIEVERS M. / et al. - ARTICLE DE PERIODIQUE - 2003

A novel on-line method and system for characterisation of sludge flocs in view of improving sludge dewatering has been developed. The system's main component is a sensor working optically by image processing via a conventional CCD line To enable on-line prediction of dewatering efficiency during the conditioning process, a concentration factor has been introduced. A sludge characteristic calculated from the measured relative floc size distribution was proven to be suitable for predicting the concentration factor. Verification of the sludge characteristic calculation is needed for sludge from different wastewater treatment plant.
