Fresh Water CO2 7 Pre-treatment 1 6 8 Re-mineralization or pH adjustment 3 2 Reverse Osmosis Process SEAWATER 5 Fresh water storage 4 The desalination process The growth in membrane technology has made reverse osmosis (RO) the most commonly used technology in desalination throughout the world. Seawater is pressurized and fed to a system that contains semi-permeable membranes. Clean water permeates through the membranes while dissolved minerals, such as salt and organic substances are retained by the membranes. This results in two water streams: one of clear, desalted water and one of reject water...

Seawater pre-treatment with membrane technology The RO membranes used for the desalination of sea- or brackish water are susceptible to biological fouling and plugging with fine silt. Therefore, pre-treatment of the water is necessary to improve RO efficiency, and to reduce energy consumption, maintenance costs and production losses. Dedicated seawater ultrafiltration membranes function as a single barrier, with a low chemical and energy consumption and a relatively small overall system footprint. Pentair X-Flow offers two dedicated solutions for seawater reverse osmosis (SWRO) pre-treatment...

Solutions for small to large installations Pentair X-Flow’s vertical and horizontal membrane configurations allow you to select the best-suited solution for your desalination plant. Matching the system with your feed water quality, site layout and need for system redundancy reduces installation and operating costs. The horizontal Seaguard system features the only UF membranes with RO style membrane housings. This allows for use at elevated pressure (>2.5 bar/36 psi), which enables an in-line design with direct feed into SWRO high-pressure pumps (direct coupling). Additional benefits are the compact...

Post-treatment: CO2 injection, pH correction Pentair Haffmans offers sustainable solutions for the post-treatment of water coming from the RO process. Re-mineralization is the process needed to make the RO water drinkable. Conventional methods such as adding chemicals fail to deliver the required permeate water quality. Pentair Haffmans’ CO2 injection system adjusts the ph value and allows the calcium (Ca+) ion to re-create some hardness and alkalinity in the water. Pentair Haffmans provides both the CO2 injection system as well as complete CO2 injection packages for pH control including: • CO2...
