In addition to the salt and dissolved ions that RO membrane systems remove, sea water can also contain algae, color, organics, soluble metals, dissolved solids and oil that can foul and damage the membranes. ITT Leopold® desalination pretreatment systems can remove these contaminants before they reach the RO membrane system. The company offers two desalination pretreatment system technologies—Leopold Clari-DAF® dissolved air flotation system and Leopold FilterWorx™ rapid gravity media filtration. They can be used individually or in combination to provide the cleanest influent to feed the RO membrane filters. The Clari-DAF system requires no polymer, has high loading rates, is compact in design and effectively operates in low temperature raw water. The FilterWorx rapid gravity media filter system has a downflow design, efficiently stores solids, handles wide swings in solids loading, and provides long filter runs with high production rates.

UF membrane system TriSep's SpiraSep™ submerged ultrafiltration process uses spiral wound membranes. Water is “pulled” through the membrane using a slight vacuum. Air “bubbles up” through the element feed channels, scrubbing the membrane surface clean. The rigid, durable structure of the system design eliminates mechanical integrity issues commonly associated with hollow fibers, preventing unwanted solids passage. The UF membranes provide a complete barrier layer which removes all particulates, offers high flux rates and low chemical usage, in a low-energy, fully automated package.
