Factors affecting uranium removal from brackish groundwater using a direct solar powered ultrafiltration-nanofiltration/reverse osmosis membrane system were investigated during a field trial in the Australian outback. The key variables were uranium speciation (as a function of pH), groundwater type as well as energy variation over the course of a day. It was found that uranium was retained by t...

Reverse osmosis is the most widely used desalination technology for treating irrigation water. removes both monovalent ions detrimental to crops (Na+,Cl?) and divalent beneficial (Ca2+,Mg2+,SO42?). Fertilizer must then be added desalinated water reintroduce these nutrients. Unlike reverse osmosis, selective electrodialysis selectively while retaining in This paper investigates selectivity cost ...

This paper summarizes a study of the economic and environmental performance of Reverse Osmosis (RO) desalination powered mainly with photovoltaics. It is based on up-to-date cost data for photovoltaic power plants and RO desalination plants. A case study is presented of a plant producing 6550 m water per day on the coast of the Red Sea in Saudi Arabia powered by 3-MWdc PV or HCPV capacities. We...

The use of renewable energy for desalination started in the 1980s, order to provide a sustainable water supply windy/sunny areas with shortages. Nevertheless, this initiative has been generally limited R&D field and prototypes, few units operating under real conditions. research tradition carried out by Canary Islands Institute Technology, based on pilot facilities, resulted wide expertise ...

Ocean waves provide a clean, reliable source of energy making them viable for desalination, especially in coastal communities and island nations. However, large capital costs render current wave-powered desalination technologies economically infeasible. This work presents configuration ocean-wave-energy-powered batch reverse osmosis. The proposed system uses seawater as the working fluid hydro-...

This paper evaluates life cycle Greenhouse Gas (GHG) emissions of a Seawater Reverse Osmosis (SWRO) desalination plant and assesses its performance under three power supply scenarios. A Life Cycle Assessment (LCA) analysis is conducted for a plant located in Perth, Western Australia (WA). Input and output flows of SWRO plant are based on literature and Perth desalination plants. The Simapro Aus...
