METHODS AND PROCESS PLANT FOR THE TREATMENT OF AQUEOUS ORGANIC WASTE STREAMS

摘要

Methods and process plant for treating aqueous organic waste or by-product streams containing water are described. The method comprises passing an aqueous organic waste or by-product stream comprising soluble and insoluble solids through a bio-digester reactor, and subjecting the stream to pervaporation separation using a membrane which permits only water vapour to be transported therethrough to generate therefrom an essentially contaminant free water stream and a stream containing an increased dry matter content as compared to said stream immediately prior to said pervaporation separation. The essentially contaminant free water stream may also be treated to make it aseptic. It is preferred the bio-digester reactor is an anaerobic reactor. Aseptic fertilizer products are also described.
