Thickening - dehydration equipment for slurry originating from purifier of residual water includes initial cavity for receipt of slurry together with vacuum dehydration system

摘要

The thickening-dehydration equipment for slurry originating from a purifier of residual water includes initial cavity for receipt of slurry together with a vacuum dehydration system supported by a membrane for filtration of the slurry arranged beyond the initial cavity. Also included are slurry press rollers supported by the filtering membrane, together with a scraper which separates the layer of slurry from the filtering membrane. Cleaning devices are provided for the lower support of the filtering membrane by means of water which afterwards is recirculated to the initial cavity for its re-use.
