Author has introduced the present study situation of the mass transfer of removing the trace organic substance by silicon rubber compound membrane osmosis evaporation at home and abroad; has presented the extending mode/for mass transfer resistance in series used in the silicon rubber com- pound membrane osmosis evaporation; has analyzed the partial resistance in osmosis evaporation process, including the boundary layer of liquid phase, tight skin layer of membrane and effeeting factor for mass transfer resistance of porous supporting layer; has obtained the calculation method to facilitate en- gineering design. Result indicates that this model has the guiding significance for further application/study and optimizing osmosis evaporation process as well.
