First Reverse Osmosis - New Mexico State University
Brackish Groundwater National Desalination Research Facility (BGNDRF), Alamogordo, New Mexico.
One HydroFLOW s38 unit and One HydroFLOW hs40 unit was installed.
Membrane scaling is generally controlled by pH adjustment, addition of antiscalant, or extensive pretreatment. The Hydropath technology is an innovative method for water conditioning, which induces an electric signal of ±150kHz in the liquid inside of a pipe on which it is installed. A specialized transducer connected to a ring of ferrites performs the electric induction. The goal of the study was to determine if the HydroFLOW devices could reduce membrane scaling during desalination of a brackish groundwater.
The HydroFLOW devices, which are powered by Hydropath Technology, could potentially provide a chemical-free alternative to control membrane fouling and scaling by inhibiting the formation of a compact scaling layer.
This study demonstrated the Hydropath is a promising technology to minimize membrane fouling. Further experiments are needed to evaluate HydroFLOW units for other types of water, at different water recovery, with addition of acids and antiscalants, and the effectiveness and duration of hydraulic flushing.
