“…The installed RO plants have reached two times of the installed thermal process based plants based on the freshwater production capacity [52; 53]. Many remote and coastal areas do not possess resources of electric power for the production of potable water by the implementation of conventional desalination techniques such as multi-stage flash, reverse osmosis and vapor compression [54][55][56][57]. Conventional processes like MSF and RO require large amounts of energy in the form of thermal energy (MSF) or electric power (RO) for functioning [58].…”

Seawater desalination and wastewater treatment for its reuse are rapidly evolving technologies as water crisis is one of the major issues around the globe. Different purification technologies and advancements in the processes, for instance variation in pretreatments for a better separation process and other related aspects are the areas frequently worked on. Evolution of water treatment techniques over last 40 years is fairly vast and new ideas related to nanotechnology are emerging in the industries with a view of more efficient functioning. The article focusses on the large scale water treatment techniques, their characteristics, relative principles, methodology and evolution. It also indicates the variety of membranes manufactured by established company over the years and emphasizes on their different properties and applications with changing compositions. The article narrows down to concentrate on the membrane separation processes as they are globally popular techniques in bulk water treatment.

“…In the development of solar desalination, linked with the improvement of solar still, studies have found that great parameters are affecting the performance of the still. The productivity of a solar still increases with the rise of the following; total solar radiation, ambient air temperature , condensation area , exposure area of the basin of saline water , and an optimum cover tilt angle of the solar still. For maximum productivity this must be close to the latitude angle of the site .…”

In this article, the validity of a numerical simulation of a basin solar still coupled with a condensation chamber was analyzed, before being cooled through a cooling water system. The system contained a serpentine pipe combined with a rectangular sheet of galvanized steel. The model was validated by comparing calculated and then experimental results mentioned in previous research for a typical day in the month of June 2013, the comparison of results showed a good agreement between the experimental and numerical tests. The model was developed to evaluate the performance of the system with optimum mass flow and compared throughout the typical day of each month of the year with that of a solar still without cooling. The model was investigated numerically according to meteorological data of the Algerian city, Khemis Miliana using the model of Capderou. The equations are modeled by the finite difference method, the Gauss–Seidel iterative method was used to solve the resulting algebraic equation. The highest productivity of the year was 6.7 Kg/m2 during the typical day of august with 60% higher productivity than the still without cooling. It was observed that the productivity of the solar still was sensitive to the flow mass of cooling water. Both the condenser chamber volume and the area from the opening of the evaporator to the condenser chamber have a significant effect on distillate production of the system. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

Summary In this paper, a novel hybrid photovoltaics/thermoelectric cooler (PV/TEC) distillation system has been introduced. The limitation for distillation system working under hot arid climate is the heat removal required for the condensation process. The novelty of the proposed system is that it utilizes TEC to improve the condensation process. The proposed system composed of two porous layers separated by an air gap. The upper porous layer is installed at the back of a PV module; the lower porous layer is installed at the top of a TEC modules layer. This system can provide the demand of electricity and potable water for those people who live in rural areas (using one unit or more). The proposed system prevents PV module from overheating and actively enhancing the condensation process of the evaporated water. A steady‐state mathematical model has been proposed. This model was solved and simulated by equation solver software. Wind speed, solar radiation, and ambient temperature effect on the system performance were simulated and discussed. Results showed that the maximum productivity of the system reached an ambient temperature of 298 K, solar radiation of 1000 W/m2 and wind speed of 5.5 m/s. The maximum yield of the system was 4.2 kg of distilled water per day with a net electrical output power of 73 W with an overall efficiency of 57.9% and PV cell efficiency of 12.32%.
