    This study is financed as a part of PAWUM and Sustainable Paper research programmes.The development of ultrasonically assisted membrane filtration system was addressed as a viable process for the treatment of waste waters in pulp and paper industries.The experimental results demonstrate the efficiency of using ultrasonically assisted membrane separation technology, particularly in producing higher permeate flux rates and meeting the environmental discharge regulations.This will lead to a more compact plant with significantly reduced capital and operational energy costs.A papent application has been filed by VTT Energy which describes the incorporation of ultrasonic field into planar and tubular membrane filters.
