Ras Abu Fontas A3 Reverse Osmosis Project – IWPP (Seawater Intake)

ACCIONA AGUA was awarded EPC of the SEADAF structure from Mitsubishi & TTCL for Ras Abu Fontas A3 project in Qatar. ACCIONA & Fichtner Engineering & Consulting Germany selected Xypex Crystalline Technology to protect the SEADAF structure from high salinity and sea water bound chemical attacks. Xypex Concentrate was applied as a two-coat application on the DAF internal walls, base slabs, upper slabs and the periphery wall surface (20,000 m²). Initially defective concrete was treated with Concentrate and Patch’n Plug Dry-Pac system before two coats of Xypex Concentrate was applied. Each vault successfully passed water tightness tests.
