Pentair X-Flow has been selected to supply its Seaflex ultrafiltration (UF) membranes to the Al Zawrah seawater reverse osmosis (SWRO) plant in Ajman, United Arab Emirates.

The UF system in the new Al Zawrah desalination plant will produce 4783 m3/h (115 MLD) pretreated seawater to feed the reverse osmosis membrane system.

Supply potable water
The end-user Federal Electricity and Water Authority (FEWA) is the utility provider for the Emirates of Ajman, Ras Al Khaima, Umm Al Quwain and Fujairah within the United Arab Emirates.

FEWA owns and operates several seawater desalination plants to supply potable water to its consumers and mainly employs reverse osmosis technology.

First time UF as pretreatment step
It is the first time however that FEWA implements UF technology as pretreatment step. The EPC contract was won by a consortium made up of the Spanish company Cadagua SA and local Ajman company Essa Engineering & Marine Services LLC.

The Al Zawrah SWRO plant, scheduled to be built and commissioned in 2012, will produce desalinated water for potable purposes. X-Flow’s UF membranes were selected by Cadagua to provide optimum pre-treatment for SWRO.

Higher RO fluxes
Pretreatment with UF 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 Capex.
