This paper introduces and proves new concept of salt dissolving in water as very tiny solid sodium chloride particles of nanovolumes, from this point of view salt water can be desalinated by collision with special surface characterized by smoothness upon nano level, high rigidity, high hardness under appropriate conditions of water launching in the form of thin laminar flow under suitable speed...

DCMD presents an opportunity to achieve desalination using low-grade waste heat and highly saline feed waters, where it may be economically competitive with RO, besides providing a very high quality product that could be used for boiler feed water and without the corrosion problems associated with metal based evaporators. Combined with high packing density polymeric heat exchangers, DCMD may al...

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...

introduction: reverse osmosis (ro) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. the aim of this research was the performance study of reverse osmosis plants for water desalination in bandar-lengeh, iran. materials and method...

Ocean thermocline energy is a sustainable and reliable heat source for seawater desalination in remote islands that has no access to primary energy. To adapt the unique features of energy, i.e., sensible with small temperature gradient, we propose novel system combining direct-spray technology multi-effect distillation (MED). The steam generator conventional MED replaced by tubeless spray evapo...

The use of desalination technologies which produce concentrated brines is acutely limited by inadequate waste brine disposal mechanisms such that the brine does not contaminate fresh water resources. The treatment of highly saline brine using freeze desalination technique trade marked as HybridICE technology was investigated at pilot scale. The capacity of the HybridICE process to generate fres...

Humidification-dehumidification (HD or HDH) desalination, and specifically HD driven by a thermal vapor compressor (TVC), is a thermal desalination method that has the potential to produce potable water efficiently in order to address the growing demand for water. This article presents a numerical study and optimization of two HD-TVC cycle configurations in order to determine the best achievabl...
