Membrion, Inc.
Ceramic ion exchange membranes towards scaling resistant electrodialysis reversal
Seattle, WA
Electrodialysis reversal (EDR), enhanced by scaling resistant ceramic ion exchange membranes, can lead to as much as 99.2% water recovery at < 4 kW/m3 when combined with RO.

Batch RO with a flexible bladder: high recovery without scaling
Cambridge, MA
Batch reverse osmosis recovers water from scaling-prone RO concentrate by operating in brief cycles that are too short for scalants to nucleate.

Pacifica Water Solutions, LLC
Groundwater Desalination Using Electrically Conducting Reverse Osmosis (ECRO) Anti-Scaling Membranes
Northridge, CA
The ECRO membrane technology minimizes the scaling and fouling potential of challenging feed waters resulting in enhanced water recovery, and reduced brine generation, reduced footprint.

Double-bonus: high-recovery concentrate treatment with salt-free electrodialysis metathesis (EDM)
El Paso, TX
Salt-free EDM produces two very high salinity concentrate streams (enabling >98% system recovery), and the EDM product can be blended with RO product.

Honorable Mentions

Four additional submissions have been named Honorable Mentions for their solutions.
Applied Membrane Technology Inc.
Vapor recompression-condensation in fouling-resistant hollow-fiber-membrane distillation-based brine concentrator-crystallizer
Minnetonka, MN
RO concentrate will be subjected to vacuum membrane distillation-crystallization in a fouling-resistant hollow-fiber-membrane device aided by vapor recompression and plastic hydrocyclone separator.

Crystal Clear
Closed Circuit Reverse Osmosis (CCRO) with Integrated Crystal Recovery
Golden, CO
CCRO can reach 16x supersaturation in gypsum or 95% recovery on Yuma feed. Plate-settler recovers gypsum crystals and hydrocyclone on supernatant recycles crystals as seeds.
