NASA’s Bioreactor Cleans Wastewater too

NASA’s bioreactor grows Algae and Cleans Wastewater:

NASA invented an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel and a variety of other products. They estimate that 10 acres of ocean could produce 21 billion gallons of biofuel each year–enough for all U.S. aviation needs. A number of airlines have already begun to test out biofuels, including Continental Airlines, Virgin Atlantic, and Air New Zealand.

The NASA bioreactor is an Offshore Membrane Enclosure for Growing Algae (OMEGA), which won’t compete with agriculture for land, fertilizer, or freshwater.

When deployed in contaminated and “dead zone” coastal areas, this system may help remediate these zones by removing and utilizing the nutrients that cause them. The forward-osmosis membranes use relatively small amounts of external energy compared to the conventional methods of harvesting algae, which have an energy intensive de-watering process.

Potential benefits include oil production from the harvested algae, and conversion of municipal wastewater into clean water before it is released into the ocean. After the oil is extracted from the algae, the algal remains can be used to make fertilizer, animal feed, cosmetics, or other valuable products.

That is not all!

This successful spinoff of NASA-derived technology will help support the commercial development of a new algae-based biofuels industry and wastewater treatment.
