Case Study

Reverse Osmosis - New Mexico State University

Customer

 

Brackish Groundwater National Desalination Research Facility (BGNDRF), Alamogordo, New Mexico.

 

Application

 

Reverse Osmosis.

 

Installed units

 

One HydroFLOW S38 unit and One HS40 unit was installed. 

 

Water source

 

Well water.

 

Background 

 

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.

 

Success factor

 

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. 

 

Results

 

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.
