  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • On the performance limitation of reverse osmosis water desalination systems

    The performance of Reverse Osmosis (RO) water desalination processes was investigated using a simulated brackish water plant based on spiral-wound membranes. A semi-rigorous mathematical model was employed in the simulation to calculate the water and salt fluxes at any point along the filtration channel. The effects of two key parameters, namely the transmembrane pressure and membrane surface ...

  • Biological filtration of poor quality brackish water reducing Reverse Osmosis membrane fouling

    Abstract A primary limitation in applying Reverse Osmosis (RO) is loss of performance caused by membrane fouling resulting from compounds that bacteria can use as energy or nutrient sources. When these compounds enter RO membranes, they are capable of sustaining extensive bacterial growths on the membrane sheets as well as within feed channel spacers. This leads to the entrapment of ...

  • Preliminary evaluation of new green antiscalants for reverse osmosis water desalination

    Supplying fresh water has become an important environmental and economic issue. Desalination with reverse osmosis (RO) represents an effective solution to meet the challenges of cleaning brackish water and seawater for drinking and industrial purposes. The principal problem of RO plant operation is the precipitation of low soluble salts (scaling). There are some well-known techniques to reduce ...

  • Evaluating impact of fouling on reverse osmosis membranes performance

    Abstract Membrane fouling is commonly defined as an undesirable formation of deposits on mem- brane surfaces and it is considered a major problem in most brackish, seawater, and waste water reclamation applications. Depending on nature of the scale and foulant, fouling pro- cesses will lead to decreased membrane fluxes, increased pressures needs, and/or increased permeate conductivity. ...

  • Optimization and economic analysis for a small scale nanofiltration and reverse osmosis water desalination system
