Filter & Separator 

Abstract: With the requirement of environment protection becoming stricter,the separation of dispersed liquid phase from other liquid like oil in water become more important and more difficult,so the development of coalescence separation is required. In this paper,some methods,mechanism and application have been presented, which include coalescence in gravity field ,coalescence in electric field , ultrasonic coalescence and cyclonic coalescence.

Abstract: In this article, the mechanism and filtration coefficient of deep bed filter are represented deeply, the influence of grain characteristic, filter material characteristic and the speed of filter to filtration efficiency are analyzed in detail, then, the development situation of filter material and filtration technology are reviewed, the prospect of the development for deep bed filter in the future is described, inventing new style filter material and continuous filter are emphasized.

Abstract: The process for the treatment of xanthan fermentation wastewater by reverse osmosis was studied in a self-developed evaluation tank of high pressure reverse osmosis system.The effect of pressure,temperature,recirculation and wastewater concentration on water -permeation --flux and desalination -rate was investigated.The washing method of reverse osmosis membrane was studied in this paper.

Abstract: With the development of contamination control technique and intensive research on filtration theory,the metallic fibre sintered fibre felt,as a new kind of filter material,is being widely used in many industries such as chemical engineering, chemical fibre, metallurgy, petrochemistry, food processing, plant equipment and environment protection.The material is constructed of stainless steel fibres (Nichel fibres) that are disorderly interwoven,rolled and sintered,which form a great amount of pores to intercept the contaminants in fluid.The material has such advantages as no shreds, high filtration accuracy and dirt holding capacity, high-temperature resistance, organic solvent resistance, corrugatability, weldability and repeated cleanability
