Pentair X-Flow received an order from Aquatech Eastern (FZE) to supply Seaflex 55 ultrafiltration (UF) membranes and skids to the 15 MIGD (68,000 m³/day) Federal Electricity & Water Authority (FEWA) Seawater Reverse Osmosis (SWRO) plant at Ghallilah, Ras Al Khaimah, United Arab Emirates.

The plant, scheduled to be operational in late 2013, has an estimated UF permeate capacity of 7,125 m3/hr on a continuous basis. The plant will provide drinking water to the Emirate of Ras Al Khaimah.

The project, owned by FEWA, will be executed by Aquatech Eastern (FZE) on a complete EPC basis including civil works, buildings, balance of plant, and electrical and mechanical installation.

The X-Flow UF membranes were selected to provide optimum pretreatment for the RO membranes. Ultrafiltration pretreatment provides higher RO fluxes and reduces RO CIP frequency. In addition, UF positively impacts all vital aspects of an SWRO plant including providing consistent RO feed water quality, a significantly smaller plant design, better performance, and reduced CAPEX.

The Seaflex UF membranes at the FEWA SWRO plant will be installed with an inline configuration, which lowers energy consumption and helps avoid contamination as additional pumps and storage tanks are eliminated. Also, operating costs are reduced as cartridge filters are not needed with this design.

Earlier this year, FEWA selected X-Flow UF membranes for the large-scale Al Zawrah SWRO plant in Ajman, United Arab Emirates. These recent project wins confirm Pentair X-Flow’s leading position in the SWRO pretreatment market.
