Working of the system The Dweer
system uses a piston double-chamber reciprocating hydraulically driven pump and a patented valve system in a high-pressure batch process with large pressure vessels, similar to a locomotive, to capture and transfer the energy lost in the membrane reject stream.
The first order includes the Campo de Dalais project, which will utilise the CALDER Dual Work Exchanger Energy Recovery (DWEER
) units made by the company.
Palm Utilities was recognised for its use of the Dual Work Exchanger Energy Recovery (Dweer
) system for the Palm Jumeirah seawater reverse osmosis (SWRO) plants, resulting in up to 19 per cent power savings and a significant reduction in carbon footprint.
