Desalination Technology and Advancement
Oxford Research Encyclopedia of Environmental Science, 2019Co-Authors: P.s. Goh, A.f. Ismail, Nidal HilalAbstract:Water scarcity as an outcome of global population expansion, climate change, and industrialization calls for new and innovative technologies to provide sustainable solutions to address this alarming issue. Seawater and brackish water are abundantly available on earth for drinking water and industrial use, and Desalination is a promising approach to resolving this global challenge. Recently, the considerable reduction in the cost of Desalination has contributed to the growing capacity for global Desalination. The Desalination technologies that have been deployed worldwide for clean water production can be categorized into two main types: membrane-based and thermal-based. Technological advancement in this field has focused on the reduction of capital and operating cost, particularly the energy consumption of the systems. Seawater and brackish Desalination technologies are promising solutions for water shortages.

solar powered Desalination Technology energy and future outlook
Desalination, 2019Co-Authors: Farah Ejaz Ahmed, Nidal Hilal, Raed HashaikehAbstract:Abstract Growing water demands have led to rapidly increasing Desalination installation capacity worldwide. In an attempt to lower carbon footprint resulting from high-energy consuming Desalination processes, attention has shifted to using renewable energy sources to power Desalination. With solar irradiation ample in regions that heavily rely on Desalination, solar powered Desalination provides a sustainable solution to meeting water needs. The compatibility of each Desalination process with the solar Technology is driven by whether the kind of energy needed is thermal or electrical, as well as its availability. With rapid advances in solar energy technologies – both photovoltaic and solar thermal, there has also been growing interest in coupling solar energy with Desalination, with a focus on improving energy efficiency. In this review, the most recent developments in photovoltaic powered reverse osmosis (PV-RO), solar thermal powered reverse osmosis (ST-RO) are discussed with respect to membrane materials, process configuration, energy recovery devices and energy storage. In addition, advances in new materials for solar powered membrane distillation (MD) and solar stills in the past two years have also been reviewed. Future outlook considers the use of hybrid renewable energy systems as well as solar powered forward osmosis and dewvaporation. Solar powered Desalination systems have been analysed with emphasis on technological and energy consumption aspects.

current trends and future prospects in the design of seawater reverse osmosis Desalination Technology
Desalination, 2012Co-Authors: Baltasar Penate, Lourdes GarciarodriguezAbstract:Abstract Seawater reverse osmosis Technology is fully mature at industrial scale which has been installed in all coastal areas around the world with limited natural hydrological resources. There are many technological advances and innovations which are trying to improve the reverse osmosis Desalination process. In particular, all pursue to reduce the process energy consumption, as well as to minimize the harmful effects of scaling and fouling on membranes and to obtain higher water flux membranes. This paper presents a comprehensive review of the main innovations and future trends in the design of seawater reverse osmosis Desalination Technology. These are intended to improve the process performance and the efficiency of this technique for high production. Special focus is placed on the use of renewable energies as an innovation in the medium-term for medium and large production capacities. It supports Desalination with renewable energies as an attractive combination in many regions with the possibility of reducing stress on existing water supplies.

analysis and optimization of the low temperature solar organic rankine cycle orc
Energy Conversion and Management, 2010Co-Authors: Agustin M Delgadotorres, Lourdes GarciarodriguezAbstract:Abstract Solar thermal driven reverse osmosis Desalination is a promising renewable energy-driven Desalination Technology. A joint use of the solar thermal powered organic Rankine cycle (ORC) and the Desalination Technology of less energy consumption, reverse osmosis (RO), makes this combination interesting in some scarce water resource scenarios. However, prior to any practical experience with any new process, a comprehensive and rigorous theoretical study must be done in order to assess the performance of the new Technology or combination of existing technologies. The main objective of the present paper is the expansion of the theoretical analysis done by the authors in previous works to the case in which the thermal energy required by a solar ORC is supplied by means of stationary solar collectors. Twelve substances are considered as working fluids of the ORC and four different models of stationary solar collectors (flat plate collectors, compound parabolic collectors and evacuated tube collectors) are also taken into account. Operating conditions of the solar ORC that minimizes the aperture area needed per unit of mechanical power output of the solar cycle are determined for every working fluid and every solar collector. The former is done considering a direct vapour generation configuration of the solar cycle and also the configuration with water as heat transfer fluid flowing inside the solar collector. This work is part of the theoretical analysis of the solar thermal driven seawater and brackish water reverse osmosis Desalination Technology. Nevertheless, the supplied information can be also used for the assessment of different applications of the solar ORC. In that case, results presented in this paper can be useful in techno-economic analysis, selection of working fluids of the Rankine cycle, sizing of systems and assessment of solar power cycle configuration.

technoeconomic study of a novel integrated thermal msf med Desalination Technology
Desalination, 2015Co-Authors: Abdel Nasser Mabrouk, Hassan E.s. FathAbstract:Abstract This work presents a novel integrated MSF–MED thermal Desalination Technology and its techno-economics as compared to conventional systems such as MSF-BR, MED-TVC, MSF-OT-LT and plain MED. The new integrated MSF–MED benefits from (i) high top brine temperature (TBT) of natural dilution seawater feed of the once through (MSF-OT), (ii) lower pumping power of long tube MSF-LT, and (iii) the low heating steam quality and cost of MED. The process calculation showed that the pumping power of the integrated MSF–MED is 58% lower than that of the traditional MSF-BR while it is 16%, lower than that of MED-TVC. The cost analysis showed that at subsidized oil price of 12 $/bbl, the unit water cost of the integrated MSF–MED is 32% lower than that of MSF-BR and 21% lower than that of MED-TVC. The unit water cost of the integrated MSF–MED is the lowest value when the oil price is lower than 40 $/bbl. This result showed the superiority of the integrated MSF–MED configuration for GCC countries since the oil price is generally subsidized. It also has a chance to utilize a diverse available energy such as waste heat and steam from backpressure or condensing turbine.
