Abstract: Systems and methods for enhancing volatile fatty acid, ammonia or dihydrogen production in fermenting bioreactors are presented. Energy efficient evaporation methods and systems are disclosed. Integration of bioreactor and energy efficient evaporation enable use in existing bioreactors. Methods for further recovering fermentation products in bioreactors used for wastewater applications are also disclosed.

Abstract: This invention discloses a method of separating volatile acids and bases from liquid mixtures in wastewater treatment and aerobic culturing processes. The method uses the colligative properties of a solution to differentially separate solvent and acid vapors and employs novel techniques such as controlled volatilization, ion separation processes, and pH management to effectively remove these compounds while optimizing process efficiency. The invention facilitates the management of carbon dioxide accumulation, crucial for promoting autotrophic reactions and improving overall system performance.
