- California-based Energy Recovery is famous for its patented PX-Pressure Exchanger, the default technology-of-choice for salt-water reverse osmosis ("SWRO") market.
- PX devices reduce energy costs as well as emissions.
- ERII owns the market, and it is thriving due to the planet's increasing need for potable water from seawater in harsh and polluted environments.
- While multi-year effort to commercialize the VorTeq product for fracking has yet to catch on, I am more optimistic about the potential for the zero liquid discharge - or "ZLD" market.
