The George Barley Water Prize competition began a year ago with more than 100 teams in pursuit of the $10 million prize. Now it is down to the final 10.
At a ceremony held on October 26, 2017 at the Field Museum in Chicago, Everglades Foundation CEO Eric Eikenberg introduced the final teams whose technologies have been judged by a panel of experts to hold the most promise for a cost-effective solution to removing phosphorus from freshwater bodies. Those teams are:
Green Water Solution, Inc. from Wellington, Florida
Green Water Solution’s two-stage solution removes particulate phosphorus by filtration, and then removes dissolved phosphorus using adsorption through the company’s BioPhree® system.

MagPi from Delta, British Columbia
This company’s solution not only removes phosphorus, but forms a by-product. Using electricity to dissolve magnesium metal, MagPi removes phosphorus to form a fertilizer called “struvite.” Oxygen and hydrogen gas bubbles that are by-products of the electrochemical process float the struvite crystals for recovery.

MetaMateria Technologies, LLC from Columbus, Ohio
MetaMateria has developed an 80% porous ceramic “sponge” that removes phosphrous at high capacity and can be reused 15 times or more.

MicroHAOPs, Inc. from Seattle, Washington
This Seattle company has developed a technology that uses a thin layer of proprietary particles (Heated Aluminum Oxide Particles) on a washable mesh surface. The collected phosphorus can be regenerated and reused, or compacted and disposed.
Restore the Natural P Cycle from Richboro, PA
Ed Weinberg’s HIX-Nano process removes phosphorus pollutants, and allows them to be recovered, reconcentrated, recycled, reused and redistributed as liquid fertilizer and non-fertilizer products.
Rocky Mountain Scientific – APR from Idaho Falls, ID
The chief technology of this company is a unique APR phosphate sponge designed to remove dissolved phosphates from water that passes through a column, bed, filter, or any other media that contains the APR solvent. This can be combined with filtration methods.

University of Idaho Team blueXgreen – CoolPlanet from Moscow, ID
This team, winner of the first phase of the George Barley Water Prize, has developed the Idaho Clean Water Machine, which mimics nature in using air, sand, rust, charcoal and electricity to act like a “Swiss army knife: for removing phosphorus from water.

University of Waterloo from Toronto, Ontario
One of two academic-based finalists, the University of Waterloo’s PhosphexTM system passively removes phosphorus compounds from water and wastewater in a gravity-driven system that uses basic-oxygen furnace slag (BOFS), a low-cost by-product of steel manufacturing, to promote adsorption and precipitation reactions.
U.S. Geological Survey – Leetown Science Center from Kearneysville, WV
The U.S.G.S. technology employs an iron oxide-based sorption media (derived from mine drainage) in a fixed bed. This process also offers the possibility of recovering the phosphorus for reuse.
Wetsus NaFRAd ULTRA from Leeuwarden, Netherlands
This winner of Stage 1 of the Barley Prize has advanced to the finals. Wetsus uses a two-step approach in which a rapid sand filter removes particulate phosphorus, while soluble phosphorus is removed through adsorption on a special granular iron oxide material.
