摘要：
EasyMED, a new MED process constructed with plates has shown good performances for desalination of salted water in laboratory. In order to prove the reliability of this process in real conditions, a three effects evaporator was operated in La Spezia (Italy). This unit is composed of three effects in series and five cells in parallel and is heated by hot water at about 75 degrees C. 3 m(3)/day of high quality distillate with conductivity lower than 20 mu S/cm was obtained. The overall heat transfer coefficients between heating water and seawater falling film reached 1400 W/m(2).,C whereas the coefficient between condensing vapour and evaporating seawater is about 4000 W/m(2). degrees C. The influence of the heating fluid temperature and the heating fluid flowrate is studied. The results were used to design a ten-effects industrial unit producing about 150 m(3)/day. The potential application of solar heat collectors to supply thermal energy to this MED plate process is studied.
