MVR is short for the mechanical vapor recompression technology. In this technology, the secondary steam and energy produced by the vaporization system is compressed by vapor compression machine, in order to improve enthalpy of the secondary steam. And then the secondary steam is supplied to the cooling tower for preheating the materials by means of cooling water circulation in it. The thermal energy is provided to the vaporization system by such circulation, thus reducing the demand for external energy. The condensate water after evaporation basically does not contain the nonvolatile matter in wastewater, which realized the recycling and reusing of wastewater.
MVR can be widely used to pre-processing of high concentration pharmaceutical wastewater and wastewater advanced treatment and reuse treatment.
