USDA Awards Skyhaven Systems’ Principals a Contract for an Industrial Relevant Microbial Electrochemical Reactor for Wastewater Processing
September 9, 2017 – The USDA solicited advancements in reusing wastewater associated with agricultural enterprises to promote improved operation with this limited resource, which upon Skyhaven Principals were awarded a contract for a new microbial electrochemical reactor. Using microbial electrochemical cells, it is possible to process wastewater to clean water while producing a marketable biofuel with a positive energy balance. Recent development work in microbial cells has shown the advantage of periodic oxygenation of the electrodes to suppress methanogenesis enabling longer life operation and a favorable production of hydrogen biofuel. However, continued operation in this manner still shows a deleterious behavior as oxygen induced biofilm growth coats the electrodes effectively shutting down the reactions over time. Additionally, it is imperative to develop and scale microbial electrochemical cells to industrial relevant capacity and longevity. Thus, Skyhaven Principals are taking on these major challenges producing an industrial relevant wastewater microbial treatment reactor include the integration of an oxygen delivery system to the electrodes and the abrasive removal of biofilms from the electrodes. With these two advancements, high throughput operation is possible for treating wastewater to clean water with the simultaneous production of hydrogen.
