ZERO ENERGY WATER
UNLOCKING THE WORLD’S MOST VALUABLE RESOURCE
Zero Energy Water (ZEW) has harnessed the extraordinary properties of graphene to create a membrane that reduces energy costs in Sea Water Reverse Osmosis (SWRO) by up to 90%.
ZEW membranes are being developed as interchangeable replacements for existing membrane elements, requiring no plant modifications for their use.
ZEW has boutique manufacturing and is taking orders for evaluation and pilot projects. We are actively seeking partnerships.
Scientific breakthrough
Our breakthrough, patented technology has enabled the development of a graphene-based coating that is applied to an industry-standard PSU layer, replacing the current polyamide layer that is used in today’s membranes. The coating:
- Has lower resistance to the flow of water
- Has higher impurity rejection rate
Hydro-Pico-Filtration
A Molecular Sieve Technology Selective for H2O Molecules
ZEW’s new porous membrane enables Hydro-Pico-Filtration (HPF) in reverse-osmosis applications, specifically allowing for the separation of compounds and ions from water, the result being ultra-pure water or water with enhanced ionic concentrations.
Compared to ultrafiltration, nanofiltration, and semi-permeable separations, Hydro-Pico-Filtration flow rates are dictated by the spacing between the graphene plates in combination with electrical charges and Van der Waal’s forces. The result is that Hydro-Pico-Filtration rejects almost everything except water molecules, filtering total dissolved solids at almost the same rejection rate as semi-permeable membranes.

Industry Compatible Membranes
Flat sheet semi-permeable membranes that will fit within existing filter designs.
Summary
Zero Energy Water (ZEW) has developed a graphene nano-plate membrane that significantly improves the volume of potable water produced per kWh of energy consumed in sea water desalination applications.
ZEW membranes are being developed as interchangeable replacements for existing membrane elements, requiring no plant modifications for their use.
ZEW has prototype-manufacturing equipment and has begun the engineering and scale-up process to enable low-volume commercial production.
