Conventional membrane systems was difficult to treatment for pulp and paper mills waste warter. Technological advances in membrane filtration systems have created opportunity for pulp and paper mills to treat effluent streams in order to meet stricter environmental constraints. "Vibratory Shear Enhanced Processing(VSEP)" developed by new logic international makes if possible to filter effluent streams without the fouling problems exhibited by conventional membrane systems. Various kinds of waste water occurred to and paper mills experiment with "VSEP" set up conventional membrane. The results were as followes : Excepting ultra filter($0.1{mu} extrm{m}$ Teflon, C-100, G-50), Nano filter(NTR-7450, DS-5, PVD-1) and reverse osmosis(ACM-4) was treated with very excellent weight of treatment, electric conductivity, removal COD, TDS, turbidity.
