0124674LoganThis project is to develop a new technology to create a biologically based source of clean hydrogen from wastewater. The main barrier to efficient conversion of dissolved organic matter in wastewater is preventing interspecies hydrogen transfer so that hydrogen generated through fermentation processes is not lost to anaerobic microorganisms. To prevent interspecies transfer, the microbes responsible for fermentation will be separated from those responsible for methane production using a two-tank membrane bioreactor. The purpose of the membrane is to control cell detention time in the first reactor so that slow-growing methanogens are not able to exist in the first tank and will therefore be unable to significantly degrade the hydrogen produced from fermentation. The reactor is to be operated in a mode that has been shown to limit membrane biofouling in suspended growth reactors.

0124674Logan该项目旨在开发一种新技术，从废水中创造出基于生物的清洁氢源。 废水中溶解有机物有效转化的主要障碍是防止种间氢转移，以便发酵过程中产生的氢不会损失给厌氧微生物。 为了防止种间转移，将使用两罐膜生物反应器将负责发酵的微生物与负责甲烷生产的微生物分开。 该膜的目的是控制第一个反应器中的细胞滞留时间，以便缓慢生长的产甲烷菌无法存在于第一个罐中，因此无法显着降解发酵产生的氢气。 该反应器的运行模式已被证明可以限制悬浮生长反应器中的膜生物污垢。
