Theoretical investigations on thermal properties of multieffect distillation (MED) are presented to approach lower capital costs and more distillated products. A mathematical model, based on the energy and mass balance, is developed to (i) evaluate the influences of variations in key parameters (effect numbers, evaporation temperature in last effect, and feed salinity) on steam consumption, gained output ratio (GOR), and total heat transfer areas of MED and (ii) compare two operation modes (backward feed (BF) and forward feed (FF) systems). The result in the first part indicated that GOR and total heat transfer areas increased with the effect numbers. Also, higher effect numbers result in the fact that the evaporation temperature in last effect has slight influence on GOR, while it influences the total heat transfer areas remarkably. In addition, an increase of feed salinity promotes the total heat transfer areas but reduces GOR. The analyses in the second part indicate that GOR and total heat transfer areas of BF system are higher than those in FF system. One thing to be aware of is that the changes of steam consumption can be omitted, considering that it shows an opposite trend to GOR.

“…To achieve effective desalination, many physical and chemical methods have been widely investigated, including thermal dynamic method, chemical method and membrane method (Greenlee et al 2009;Jing et al 2009;Mtombeni et al 2013;Zhao et al 2011). As a novel method for seawater and industrial wastewater desalination, electrosorption has the unique features of low cost, high antipollution ability, environmentally friendly and simple operation (Wang et al 2012).…”

This paper investigates a new type of carbonbased electrodes, which were equipped with graphite and activated carbon fiber composite, to improve the performance of electrosorption. The results indicated that the highest desalination efficiency achieved 55 % and the optimal condition was 1.6 V voltage, 60 min retention time and 1.0 cm electrode distance. Freundlich isotherms successfully fitted with the respective behavior of the composite electrode and provided theoretical evidence for the desalination performance improvement. Applied in real black liquor of refined cotton, the graphite and activated carbon fiber composite electrodes achieved high removal efficiency for conductivity (59 %) and COD Cr (76 %). Similar removal performance was also observed in sodium copper chlorophyll wastewater, and removal efficiency was 37 % for conductivity and 14 % for COD Cr . For the first time, this research demonstrated the biodegradability improvement in real industrial wastewater via electrosorption treatment, suggesting a potential pretreatment technique for high-salinity wastewater.
