“…The membrane distillation-crystallization has also been developed to recover other valuable organic and inorganic resources such as ammonia, heavy metals, and proteins [107]. In another work, Son et al [108] developed a hybrid system involving SWRO-MD-FO (Figure 16) in order to achieve zero liquid charge by circular brine reclamation. In this system, the SWRO brine was heated before entering the MD process as a feed and the concentrated brine from the MD outlet served as the draw solution for FO.…”

Membrane distillation (MD) is a developing membrane separation technology for water treatment that involves a vapor transport driven by the vapor pressure gradient across the hydrophobic membrane. MD has gained wide attention in the last decade for various separation applications, including the separation of salts, toxic heavy metals, oil, and organic compounds from aqueous solutions. Compared with other conventional separation technologies such as reverse osmosis, nanofiltration, or thermal distillation, MD is very attractive due to mild operating conditions such as low temperature and atmospheric pressure, and 100% theoretical salt rejection. In this review, membrane distillation’s principles, recent MD configurations with their advantages and limitations, membrane materials, fabrication of membranes, and their surface engineering for enhanced hydrophobicity are reviewed. Moreover, different types of membrane fouling and their control methods are discussed. The various applications of standalone MD and hybrid MD configurations reported in the literature are detailed. Furthermore, studies on the MD-based pilot plants installed around the world are covered. The review also highlights challenges in MD performance and future directions.

“…Usually, most of the coal chemical wastewater was treated by a zero discharge process, and after membrane concentration, inorganic ions (Na þ , Ca 2þ , Cl À , etc.) were separated from the brine by evaporation technology (Son et al 2021). Among the more mature evaporation technologies, Multiple Effect Distillation (MED) and Mechanical Vapor Recompression (MVR) were processing technologies with falling film evaporator as the core, and their excellent evaporation characteristics made them occupy an indispensable position in the field of desalination (Kouhikamali et al 2014).…”

It was important to master firstly scaling mechanism to slow down scaling, which was one of the important problems faced by saline wastewater treatment with falling film evaporators. In this paper, the phase equilibrium data of ternary system NaCl-CaCl2-H2O at 303.15–373.15 K were measured, and the prediction of the flow characteristics and scaling tendency of salt-containing wastewater in the evaporation tube was investigated by numerical simulation based on the phase equilibrium results. The results showed that the mesostable phase diagram of the ternary system was of simple type, and w(NaCl) and w(CaCl2) showed regular variation with temperature when w(NaCl) in the system was 15–28%. Moreover, the components of the four saline wastewaters (10% NaCl + 9, 10, 11, 12% CaCl2) with less salt content had a faster heating and a faster rate of evaporation of the liquid film in the evaporation tube. Based on the solubility in the experiments and simulations, it was concluded that NaCl crystals were precipitated at tube lengths of 718 mm, 942 mm, 966 mm, and 1,000 mm for four salt concentrations in the evaporation process by comparison, and the reliability of the predicted loci was also demonstrated by a falling film evaporation experimental setup.

“…13 The MD process has been used to treat RO brine water to improve its water production rate. [14][15][16] In addition, the heat driven source of MD can make full use of lowgrade energy such as solar energy, geothermal energy, industrial waste heat and so on, so that the energy consumption of MD technology can be significantly reduced compared with that of RO, and the reduced water cost can also be more easily accepted by local farmers. In addition, MD technology can take advantage of the structural characteristics of rural houses and use the sufficient solar energy of the open roof as its heat source, thus basically achieving zero cost of rural groundwater purification as envisaged in this study (Figure 5).…”

The vast rural drinking water sources along the Yellow River basin in Henan Province mainly come from the local high-salinity groundwater, which cannot be directly drunk. Zeolitic imidazolate framework-71/polyvinylidene fluoride hollow fiber composite membrane was applied to treat rural groundwater through membrane distillation technology. The variations of water quality parameters from 12 different rural regions after membrane distillation treatment were well analyzed and compared. Membrane separation performance for water samples from different regions during the membrane distillation process was investigated, including water flux and salt rejection. During a continuous 24-h membrane distillation process for the treatment of these water samples, hollow fiber membrane exhibits high solute retention rates (>99%) for salt ions, suspended solids and total dissolved solids, which are within the limits of national standards (GB 5749-2006), meanwhile membrane permeation water flux can remain stable. After the acid-cleaning for 180 min, all hollow fiber membranes can recover water flux well with a flux recovery rate above 98%. Even if the concentration ratio continued to increase, the water production rate of membrane distillation was basically maintained between 50% and 60%, which was obviously higher than the 30% of the reverse osmosis process. The economic analysis confirmed that the water production cost varied between US$0.45 and US$0.29/m3. With the extension of membrane service life, the specific membrane cost decreased rapidly in the first 6 years and then leveled off. The proposed vacuum membrane distillation process proved to be a promising water purification method for treating rural high-salinity groundwater.
