  • Cogenerative seawater reverse osmosis. Part 1: elements characteristics

    This work is a part of an extensive study performed in the area of cogenerative seawater Reverse Osmosis (RO) design, appraisal and rehabilitation. It is concerned with large-scale contiguous seawater RO systems, focusing on the 8040-type membranes of high-flow and high-salt rejection ranging in area from 300 to 400 ft². Seventeen types of membranes are selected between large- and medium-sized ...

  • 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 ...

  • Application of high flux brackish water thin film composite membranes in the desalination of highly saline ground water

    The improvements in flux and membrane designs have enabled us to install smaller and economical two-stage reverse osmosis systems suitable for small village communities situated near coastal areas to provide safe drinking water. In addition, the advent of higher productivity and better salt rejection membranes has allowed us to operate the systems at low pressure in both stages. Our two-stage ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • High performance boron removal from seawater by two-pass SWRO system with different membranes

    Boron in the desalinated water produced by the seawater reverse osmosis (SWRO) system is one of the most challenging issues for drinking or irrigation water uses. In recent years, many post-treatment methods and designs for boron elimination have emerged and attracted lots of attention, but only a few cases have demonstrated high performance and economic efficiency. The main aim of this work was ...

  • Depth exposed membrane for water extraction (DEMWAX) for seawater desalination

    Introduction The Depth Exposed Membrane for Water Extraction (DEMWAX) is a novel approach to both fresh surface water treatment and seawater desalination that deploys a system directly within the source water body. The DEMWAXTM system is configured to take advantage of the natural (free) pressure of the source water body to drive a membrane process. This configuration has many advantages ...

  • Removal of micropollutants and NOM in carbon nanotube-UF membrane system from seawater

    One of the main problems for seawater reverse osmosis desalination is membrane fouling associated with natural organic matter. Bisphenol-A (BPA) and 17α-ethinylestradiol (EE2) are well-known endocrine-disrupting compounds that have been detected in wastewater and seawater. In this study, the contribution of carbon nanotubes (CNTs, single-walled carbon nanotubes) to membrane fouling control and ...

  • Bench-scale testing of SW desalination using NF

    A majority of Southern California municipalities, including the City of Long Beach, depend on water purchased from the Metropolitan Water District of Southern California. However, due to over-allocation of the Colorado River, this water supply could potentially be restricted in the future. Consequently, the Long Beach Water Department (LBWD) is considering the construction of a 10 million gallon ...
