Abstract

Dewatering process is an important process to reduce and solidify sludge, and people are asking for an effective machine. Further, because of increased interests in the global warming due to CO2 emission, a machine with not only with good dewaterability but also with low power consumption is desired. Rotary Press Filter is a sludge dewatering machine with new structure that has been introduced by Fournier Industries Inc. in Canada and is now being manufactured and sold by Tomoe Engineering. In addition to its features such as low power, simple structure, space saving, and less wash water, this dewatering machine is suitable for the new times in respect of maintenance and control. Since its introduction, number of units installed has been increasing year by year. In Japan we have installed 44 units for dewatering of sewage sludge, plant wastewater sludge, etc. Among them, 11 units have been installed for dewatering of papermaking wastewater sludge. In this report, I will introduce Rotary Press Filter’s performance and effect of introduction.
