With an increase in demand of freshwater and depleting water sources, it is imperative to switch to seawater as a regular source of water supply. However, due to the high total dissolved solid content, it has to be desalinated to make it drinkable. While desalination technologies have been used for many years, mass deployment of such technologies poses a number of challenges like high energy re...

This work suggests a solution for preventing/eliminating the predicted Sea Level Rise (SLR) by seawater desalination and storage through large number of plants distributed worldwide; it also comprises that desalinated can resolve global water scarcity complete coverage demand. level rise be prevented desalinating additional accumulated into oceans annually human consumption, while excess amount...

Greenhouse cultivation in the Mediterranean region has undoubtedly enhanced economic growth and generated social benefits by making an efficient use of resources. However, these production systems caused undesirable environmental impacts. In order to move towards cleaner greenhouse areas, this study assessed potential trade-offs integration on-farm reverse osmosis system powered photovoltaic so...

The objective of this study was to evaluate the effects of fluctuating energy and pH on retention of dissolved contaminants from real Australian groundwaters using a solar (photovoltaic) powered ultrafiltration – nanofiltration/reverse osmosis (UF-NF/RO) system. Four NF/RO membranes (BW30, ESPA4, NF90, and TFC-S) were used. Energy fluctuations affected pressure and flow. Solar irradiance levels...

in this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. a polyamide spiral wound ro membrane followed by three filters as ro pretreatment (two activated carbon and one cartridge filter) and samples of tehran refinery treated waste water have been used. the effect of operating conditions such as pressure difference...

The pressing problems of water scarcity in many parts the planet make desalination one technological solutions for guaranteeing fresh supply. However, processes require high energy consumption, mainly provided by fossil fuels. integration renewable sources into is a promising option decarbonizing sector. As most water-scarce regions with access to seawater frequently have solar irradiation leve...

This work focuses on the design of a supervisory predictive control system for the optimal management and operation of a stand-alone wind-solar energy generation system which provides power to a reverse-osmosis (RO) water desalination system. We design the supervisory control system via model predictive control which coordinates the wind and solar subsystems as well as a battery bank to best sa...

Background & objectives: Nowadays, according to membrane-based filtration processes; the use of substances such as antiscalants that prevents the formation of deposits during the treatment process, is very important from industrial point of view. This study aimed to synthesize styrene-maleic anhydride copolymer (PSMA) using the radical polymerization method and to investigate the factors and pa...
