MUMBAI, India, Sept. 14 -- Intellectual Property India has published a patent application (202617066586 A) filed by Fluid Technology Solutions Fts, Inc. on May 27, 2026, for Use Of Pressure Recovery Devices As Reinjection Pumps For Brine Concentration Nanofiltration Systems.
Inventor includes Schutter, Mark.
The application for the patent was published on September 11, 2026, under issue no. 37/2026.
Abstract: Embodiments disclosed herein are nanofiltration membranes, systems, and methods to handle high concentration brine streams while minimizing the corrosive effects on the pumps used to move these high concentration brine streams. In an embodiment, a brine concentration nanofiltration system includes one or more first sets of nanofiltration elements, one or more second sets nanofiltration elements, and one or more pressure recovery devices. A pressure recovery device of the one or more pressure recovery devices includes a low-pressure side through which at least a portion of a filter permeate flow from the one or more second sets of nanofiltration elements is fed and a high-pressure side through which at least a portion of a process feed brine from a high-pressure process feed pump is fed. Outputs of the pressure recovery device include a high-pressure filter permeate output and a low-pressure feed fluid output.
