Small and compact ERD for small SWRO units
An energy-recovery device for small seawater reverse-osmosis (SWRO) systems has been launched by Danfoss RO Solutions, manufacturer of APP high-pressure pumps and iSave energy-recovery devices.
The device differs from similar devices on the market by ensuring low ripples and a smoother operation without using a pulsation damper. By adding two pistons more than are used in other devices, the pulsations are minimized and the lifetime of the membrane is increased.
The RO-Boost can produce up to 3,000 L/d at a recovery rate of 13% and is suitable for small RO water-makers where space and energy requirements are a constraint, such as sailing boats and small land-based RO systems.
The small size, compactness and low energy requirements of the RO-Boost makes it a good choice in mobile RO application such as those used in emergency relief areas and military applications.
