Porous TiNO solar-driven interfacial evaporator for high-efficiency seawater desalination

High - efficiency seawater desalination via NF / RO multi - pass arrays

In recent years, capital and operating costs of seawater desalination plants have decreased remarkably. However, production of potable water from seawater by reverse osmosis membrane desalination remains 2 to 3 times the cost of desalting brackish water, reclaiming wastewater, or importing fresh water even over long distances. In addition, rejection of boron by seawater RO membranes is generall...

Experimental Study of Humidification-Dehumidification (HDH) Seawater Desalination Driven by Solar Energy

Electrochemically mediated seawater desalination.

With global demand rising faster than availability, fresh water is quickly becoming a limited resource. In fact, the United Nations estimates one third of the world s population is living in water-stressed regions, and by 2025 this number is expected to double. Seawater desalination is an attractive solution to this problem because seawater accounts for more than 97% of the world s water supply...

Solar-Driven Integrated Ro/Nf For Water Desalination

This article presents an experimental study where two different modules are integrated, i.e. a reverse osmosis (RO) module, and a nanofiltration (NF) module, for brackish water desalination unit. Photovoltaic (PV) panels power the setup. The performance for each of the modules was evaluated separately. Then both modules were integrated together, either in series or in parallel. The performance ...

Solar Power Technologies for Desalination

Throughout the world, there are regions of vast extent that have many favorable features, but whose development is principally limited by the lack of fresh water. In arid areas where large-scale development has already occurred, e.g. parts of the Middle East and North Africa, the extraction of fresh water via desalination plants requires very large energy consumption. This motivates the develop...
