UVM Reference Number: C816
Summary:
Portable EFO device which is easy and low cost to maintain, durable and environmentally friendly with no harsh chemicals needed
Background:
Saline, the lifeblood of all hospital/medical systems, is supplied by only five or fewer companies in the United States. Currently, the United States market for saline is estimated at $3 billion per year and is rising. While saline is inexpensive, supply is restricted due to limitations in the manufacturing and transportation process. Challenges include but are not limited to saline quality problems, insufficient production capacity, a lack of local/regional production facilities and continuation of supply during crisis.
Technology Overview:
The EFO device uses a new and innovative low-power membrane-based osmotic approach that allows for the easy local production of saline under any scenario. By employing an alternating current perpendicular to the membrane, contaminants in the water are ionized which prevents them from sticking to the membrane during operation. As a result, the device can use local, low-quality (marginal) water sources, including, but not limited to, river water, pond water, and gray wastewater, to produce medical saline that can augment existing saline supplies in times of crisis. The device can be run on solar/battery power, or even simple hydraulic pressure. In addition to saline production, the EFO is a general-purpose forward osmosis device that can be used in many different applications that require purifying marginal water.
Benefits:
- Environmentally safe - unique anti-fouling technology that does not use any chemicals.
- Portable – small size makes it easy to transport and produce saline where needed
- Low energy cost – does not require high energy pumps to operate
- Low maintenance – self-cleaning technology reduces maintenance requirements
- Durable – eliminating harsh chemicals and pressure scrubbing prolongs membrane life
Applications:
- On location, medical grade saline production.
- Applications where purified water is needed, including agricultural and other medical needs.
