Another part from that report that I found rather interesting...
"The focus of this work was to use AGES/KDS technology to prepare recycled papermill sludge for further processing. The AGES/KDS sludge drier can be easily located at the end of the traditional sludge dewatering process. It renders wet sludge into a dry, non-odourous, easy to handle material. The specific aim of this investigation is qualify the available fibre in the dried sludge material for re-use in the papermaking process.
Material & Methods
Raw sludge (approximately 50% dry material) was collected from three recycled paper mills. The mills selected represent a range of recycling operations in North America. They included a recycled newsprint mill (NP), a combination recycled newsprint and tissue mill (NP/TM) and a recycled tissue mill. The materials were successfully treated in the KDS Micronex to dryness as shown in Figure 1."
