Novel methods for monitoring the sludge dewatering operation of a belt filter: a mill study
Source abstract
Abstract
Abstract During recent decades the quality of pulp and paper mill sludge has changed. This has awakened the need for an applicable means to observe the sludge dewatering process diversely and accurately. To maximize the solids content and energy efficiency of board mill sludge dewatering, different process monitoring options were studied. Novel methods for monitoring the sludge dewatering operation of a belt filter were tested. Continuous run-time measurements and test response experiments were carried out at a board mill site. IR transmittance measurement through the filter web and sludge mat thickness measurement using a light curtain turned out to be very promising techniques. IR transmittance responded to the polymer content of the sludge without a notable time lag, while the solid content measurement of the filtrate did not give a measurable response.
