Atmospheric reaeration process plays a key role in degradation of organic matter and self-purification processes affecting dissolved oxygen (DO) concentrations in rivers and streams. Moreover, water quality (WQ) processes can be highly dependent on flow velocity conditions. Where, highly reaeration rates are positively correlated with high flow velocity. Therefore, the present work reports deep insights on the role of flow velocity with reaeration process in the concentration of DO and biochemical oxygen demand (BOD5). This study was applied along the largest agricultural drainage water reuse project, El-Salam Canal in Egypt. The hydrodynamic (HD) characteristics and WQ parameters (DO and BOD5) along the canal were simulated using a one-dimensional HD and WQ model (MIKE 11). The simulated results indicated that the canal was deteriorated towards El-Salam Canal after mixing with El-Serw and Bahr Hadous drains. Statistical regression fitted line and Pearson correlation analysis, were performed on the simulation results of the reaeration rates with flow velocity and WQ values, indicating a significant correlation. Accordingly, water velocity should be taken into account as a key factor for describing the WQ change.

“…The limited studies on the MD applications by using surface modifications of the membranes are found in the literature [96][97][98][99]. Different membrane preparation methods have been used by the researchers such as surface segregation [62,100], cross linking [64,101], coextrusion [102], plasma polymerization [91], coating [4], grafting [63], phase inversion [103][104][105], and spinning technology [106,107]. The most of the publications on the fabrication of membranes for MD applications are found from the year 2009 to 2013.…”

“…The heat lost by the conduction is lower; hence, AGMD is using an energy efficient module. The latent heat can be recovered during the condensation of the vapor on cooling plate in the AGMD configuration [61][62][63][64]. Hence, the modified MD processes such as memstill technique [65], Scrab AB systems [66,67], and Fraunhofer ISE MD module [68] are based on the AGMD configuration.…”

A B S T R A C TMembrane distillation (MD) is a non-isothermal separation process driven on the vapor pressure difference, induced by the temperature difference across the hydrophobic membrane. This paper offers the review of the potentability of MD process for purification application and water desalination. It covers the basic fundamental of MD process, MD modules, membrane materials, heat and mass transfer phenomena, operating parameters, and performance of MD process. It also covers the review of MD processes driven by renewable energy sources and current innovations in the process. The recent research results in these different areas are presented and discussed. The multi-effect MD process is found to be a new generation MD process and attractive research area in the wastewater treatment and purification application for the commercial approach.

“…The AGMD has a disadvantage that it has a low 41 permeate flux due to the additional resistance to mass transfer 42 [14]. But the main advantages of AGMD configuration are low 43 conductive heat losses, low temperature polarization effect and 44 possible internal heat recovery [15][16][17][18][19][20], and lower chance to 45 surface membrane wetting because the absence of direct contact 46 between the membrane and permeate side due to an air gap [21].…”

“…MD process is known for more than 16 50 years [3]. The MD has been extensively studied for the various 17 processes such as desalination of seawater or brackish water, 18 concentration of solutions, removal of volatile organic compounds, 19 removal of heavy metals and toxic elements from water and other 20 separation and purification processes [4][5][6][7][8][9]. MD has significant 21 advantages over other processes such as it operating at low 22 temperature and the ability to run at low pressure.…”
