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.
