Sea Water Desalination
The desalination of sea and brackish water is of ever increasing importance as a source of potable or process water. We offer both membrane and thermal-based desalination systems manufactured using high-quality raw materials.
Reverse osmosis is a tried and tested technology for the production of desalinated water by means of special membranes that filter out salt. With low power requirements, our ergonomically advantageous RO plants in various sizes are technically proven solutions to provide optimum quality water for drinking or process applications.
This process is used to transport salt ions from one solution through ion-exchange membranes to another under the influence of an applied electric potential difference. In application, electrodialysis systems can be operated as continuous production or batch production processes. In a continuous process, feed is passed through a sufficient number of stacks placed in series to produce the final desired product quality. In batch processes, the diluate and/or concentrate streams are re-circulated through the electrodialysis systems until the final product or concentrate quality is achieved.
The thermal desalination process is based on evaporation and the subsequent condensation of the steam. Sea and brackish water are separated into two flows consisting of a freshwater stream (condensate in thermal processes) with a low salt content and a stream with a high salt concentration (brine or concentrate) utilizing thermal energy.
