VSEP is a high performance liquid/solids separation system capable of attaining high flow rate over conventional crossflow membrane system. It is because that the filter pack moves in a vigorous vibratory motion tangent to the face of the membranes which prevent the membranes from fouling and plugging.
Application of VSEP were studied for paper mill effluent of white water and color coat waste water. For white water, permeate water quality was similar level to make-up water for recycle in the plant, although it needs periodical chemical cleaning which interval is considered to be prolonged. For the experiment of color coat concentration, VSEP was able to concentrate up to 40% suspended solid and which result shows that the recovered color coat is able to be reused in the plant and also has benefit such as to reduce the load of waste water treatment facility to which the color coat waste stream is large loading.
