The Ta’ Barkat facility, Malta’s largest wastewater treatment plant, plays a central role in the country’s national water reuse strategy, supporting the production of potable reuse–quality water. Under an EPC tender, ROTEC, in partnership with AST, was selected to provide its proprietary Flow Reversal Reverse Osmosis (FR-RO) technology to upgrade the plant’s advanced treatment process and expand the production of high-quality reclaimed water suitable for potable reuse applications. 

The FR-RO system is designed to treat tertiary effluent and produce up to 10,000 m³/day (approximately 2.6 MGD) of reclaimed “New Water,” operating at up to 90% recovery on high salinity feed.  By enabling stable, high-recovery operation, the system reduces brine volumes, improves overall water efficiency, and supports Malta’s long-term potable reuse and water security objectives. Integrated energy recovery and a robust mechanical design further contribute to reliable and efficient plant operation. 

With fabrication and assembly nearing completion, the project is progressing toward factory acceptance testing, shipment, and installation at the Ta’ Barkat Water Reclamation Plant. ROTEC will continue to support commissioning and operational ramp-up in close coordination with the EPC team and local operators.
