Abstract: MVR evaporator is a kind of evaporator which uses the recompression of the secondary steam as the heatingsource and is the whole recycling of the second steam. In recent years,there have been applications in wastewatertreatment and bio-chemical industry,but there are also some problems. These problems are mainly due to insufficientproduction capacity. The evaporation parameters are unstable; The discharging concentration is unstable;the fouling isserious and the evaporation effect is not good. This paper will discuss the above issues.

Key words: MVR evaporator;existing problems;selection;considerations
