Growing global water demand has brought desalination technologies to the forefront for freshwater production from nontraditional sources. Among these, forward osmosis (FO) is a promising two-step process (draw dilution and regeneration), but it often overlooked due energy requirements associated with draw regeneration. To address this limiting factor, we demonstrate FO using thermally responsiv...

In wireless sensor networks energy is a valuable but not necessary scarce resource. While it is often assumed that nodes in sensor networks are powered by batteries, other energy sources such as solar power may provide unlimited energy resources to a changing subset of the nodes. Since these nodes can receive and transmit packets without consuming battery power, routing via these nodes is appea...

Desalination that produces clean freshwater from seawater holds the promise of solving the global water shortage for drinking, agriculture and industry. However, conventional desalination technologies such as reverse osmosis and thermal distillation involve large amounts of energy consumption, and the semipermeable membranes widely used in reverse osmosis face the challenge to provide a high th...

Hypersaline brines are of growing environmental concern. While high-salinity desalination and zero liquid discharge (ZLD) increasingly attractive treatment options, the high salt scalant contents pose considerable technical difficulties to existing techniques. In this review, we introduce sources hypersaline brines, examine factors driving desalination, present thermodynamic minimum energy ZLD,...

One of the necessities human beings in this century is potable water supply. This supply has more environmental benefits if supplied by renewable energy resources. In paper, a combination combined cooling and power system (Goswami cycle), with reverse osmosis sodium hypochlorite plant powered geothermal resources proposed. The products are electrical energy, water, hydrogen salt. To investigate...

A novel thin-film composite (TFC) reverse osmosis (RO) membrane was developed by the interfacial polymerization (IP) of trimesoyl chloride (TMC) and m-phenylene diamine (MPD) on the hollow fibre ultrafiltration polysulphone (PS) membrane. The performance of the TFC membrane was optimized by studying the preparation parameters, which included monomer TMC concentration, monomer MPD concentration ...

The natural potential of Chile—solar energy and 8 km coastline—make the implementation small-scale reverse osmosis desalination plants (RODPs) in coastal areas energetically supported with photovoltaic systems (PVs) feasible. This work considers a survey Chile. As demonstration RODP, technical/economic evaluation is carried out, analyzing four possible cases which different configurations are p...

This work aims to design and dynamically simulate a polygeneration system that integrates solar-assisted desiccant cooling for residential applications as an alternative vapor compression systems. The overall plant layout supplies electricity, space heating cooling, domestic hot water, freshwater single-family townhouse located in the city of Almería Spain. leading technologies used are photovo...
