The RO-SW series from Watercore are an ideal source of fresh water to irrigation, commercial or industrial applications when the main water intake is close to shore and have a higher than acceptable salinity.
The RO-SW series from Watercore are reverse osmosis systems designed to process and provide drinking-quality water from high-salinity water or seawater. These water treatment units are typically designed for high salinities (35000 mg/l TDS) and operating recovery rates between 30% and 40%.
These reverse osmosis plants are an ideal source of fresh water to irrigation, commercial or industrial applications when the main water intake is close to shore and have a higher than acceptable salinity.
Based on the source water salinity they process, desalination plants can be divided into three main groups: nanofiltration (softening) plants, brackish water desalination plants, and seawater desalination plants.
Reverse Osmosis desalination applied to seawater is the most cost-effective system capable of converting seawater into drinking water in one single pass.
Considering that Australia’s surrounding Oceans have an average salinity of 31 g/l, reverse osmosis desalination plants are remarkably cheaper to build and maintain than the old heat distillation processes.
Typical salinity levels for water found in oceans, lakes and rivers are:
