RO desalination

The present paper describes pilot plant development of a novel process enabling increase of water recovery in brackish water desalination without using any chemicals. This is achieved by precipitating the scaling salts of a carbonate-rich concentrate by increasing the pH through air stripping of CO2

A comparison of many organic working fluids was made. Emphasis was given to the efficiency of the thermodynamic cycle using each working fluid, as well as its environmental impact. The thermodynamic cycle consists of two stages: high temperature and low temperature. The maximum temperature of the fi

Seawater desalination of interest is rising to overcome water scarcity. Especially, desalination using RO membranes is increasingly being used for production of drinking water for brackish and/or seawater. SWRO has operational problems that can be caused by various membranes fouling including partic

This paper presents the technical characteristics as well as an economic comparison of two autonomous desalination systems. The first system concerns the laboratory experimental results of a direct coupled PV-SWRO desalination system without batteries equipped with a hydraulic energy recovery device

The tendency of solutes in input water to precipitate efficiency lowering scale deposits on the membranes of reverse osmosis (RO) desalination systems is an important factor in determining the suitability of input water for desalination. Simulated input water evaporation can be used as a technique t
