Pulsar’s Sludge Finder 2 accurately measures interface levels in primary or secondary settlement tanks and SBR systems. Operating ultrasonically through liquid, the system uses echo processing algorithms to identify the sludge interface level using digital echo processing techniques.
For municipal and industrial applications, sludge dewatering with belt filter presses and plate filter presses has proven to be an economical means of reducing sludge volumes produced from wastewater treatment plants. Depending on the volumes to be treated, payback periods on the capital cost of a dewatering plant can be as little as three months and rarely exceeds 16 months. John Koumoukelis reports:
