X-Flow UF pretreatment chosen for Al Zawrah SWRO

Cadagua SA has chosen ultrafiltration (UF) pretreatment from Pentair X-Flow for the Al Zawrah seawater reverse osmosis (SWRO) desalination plant in Ajman, United Arab Emirates.

The Seaflex UF system in the new plant will produce 115,000 m³/d of pretreated seawater to feed the RO system.

The Al Zawrah SWRO plant, scheduled to be built and commissioned in 2012, will produce desalinated water for potable purposes. The EPC contract for the Federal Electricity & Water Authority was won by a consortium of Cadagua and local Ajman company Essa Engineering & Marine Services LLC.

X-Flow's UF membranes were selected by Cadagua to provide optimum pretreatment. Pentair says pretreatment with UF for SWRO allows for higher RO fluxes and has a positive impact on all vital aspects of a SWRO plant - ranging from a consistent quality of the RO feed water to a significantly smaller plant design, a better performance and a reduced capital expenditure.
