  • Seawater Desalination

    Seawater covers 71% of the planet surface and represents 97% of the world's water,and seawater has a lot of resources to be explored.Along with recycled wastewater, it is one of the few rainfall-independent water sources.However,in the current condition,seawater cannot be used directly because of the high salinity.To solve it,many methods of desalination are adopted. Desalination is a process ...

  • Artificial intelligence for predicting solar still production and comparison with stepwise regression under arid climate

    Forecasting the efficiency of solar still production (SSP) can reduce the capital risks involved in a solar desalination project. Solar desalination is an attractive method of water desalination and offers a more reliable water source. In this study, to estimate SSP, we employed the data obtained from experimental fieldwork. SSP is assumed to be a function of ambient temperature, relative ...

  • Seawater desalination and serum magnesium concentrations in Israel

    With increasing shortage of fresh water globally, more countries are consuming desalinated seawater (DSW). In Israel >50% of drinking water is now derived from DSW. Desalination removes magnesium, and hypomagnesaemia has been associated with increased cardiac morbidity and mortality. Presently the impact of consuming DSW on body magnesium status has not been established. We quantified ...

  • Study on the nucleation aspects and morphology of reverse osmosis desalination scales with and without scale inhibitor at different supersaturation ratios

    Nucleation and crystallization studies of CaSO4.2H2O were carried out under simulated conditions of scale formation in the reverse osmosis desalination technique. Equal molar ratios of CaCl2 and NaSO4 aqueous solutions were mixed with saline solution of NaCl (40 g/L). Turbidity measurements were carried out for the mixed solutions at different time intervals to ...

  • Facile synthesis of novel hierarchically porous carbon derived from nature biomass for enhanced removal of NaCl

    In this work, the hierarchically porous biomass carbon (HPBC) was originally prepared for desalination through a simple activation of cheap biomass carbon (BC). Such crucial activated conditions as the KOH/C ratio, the activation time and the activation temperature were deeply investigated. It is demonstrated that the activated conditions had a great influence on the structure properties and ...

  • OTEC in Paradise: The Philippines

    Paradise Legend has it that the Republic of the Philippines was born when the gods tossed 7,100 pearls into the ocean and islands popped up. Centrally located in Southeast Asia – just North of Australia and Indonesia, South of Japan and China, and East of Thailand and Singapore – the Philippines are considered by many to be the gateway to and from the Pacific. With ...

  • Implementation of dynamic working condition seawater desalination system optimization and simulation model

    Freshwater is an increasingly important research topic in the 21st century, similar to the importance of coal and oil in the 19th and 20th centuries, respectively. To expand expertise on desalination systems, this study aims to design a set of seawater desalination systems with dynamic working conditions based on the visualized development platform LABVIEW. The optimization searched for the ...

  • Grafted cellulose acetate reverse osmosis membrane using 2-acrylamido-2-methylpropanesulfonic acid for water desalination

    Reverse osmosis (RO) membranes based on cellulose acetate (CA), were prepared using a phase inversion technique. To improve the hydrophilicity, salt rejection and water flux of these membranes, a novel grafting of 2-acrylamido-2-methylpropanesulfonic acid (AMPSA) was added on the top surface of the CA-RO membranes. The grafted CA-RO membranes were characterized by Fourier transform infrared ...

  • Desalination plant in Egypt runs on wind & sun

    Fortis Wind Energy (NL) and Juwi Renewable (DE) install a 100kW hybrid system in Egypt. Egypt, the land of the pyramids, is known to us for its ancient culture and the last year because of the uprisings for more democracy. Egypt is less known for its large population (83 million) lives along the Nile (only 5.5% of the surface). The rest of the country is desert. The River Nile runs into Egypt ...

  • Technical and economic evaluation of an off-grid solar desalination system in Myanmar

    Myanmar is a unique country where the majority of the people live in rural areas, away from grid electricity and reliable water supplies. The penetration of grid electricity in rural areas is minimal and even then it is often erratic. This paper focuses on the challenges of transitioning from an electricity-poor country to a renewable energy based-economy augmented with photovoltaics (PV). ...
