The integrated biohydrogen reactor clarifier system (IBRCS): setup, performance, and application

摘要

1. Decoupling of SRT from HRT in biohydrogen production systems validated the promise of using a gravity settler after a CSTR 2. IBRCS decreased biomass washout by maintaining a high biomass retention time 3. IBRCS showed stable performance over a period of 100 days using glucose as a synthetic waste & corn syrup as a real waste 4. Average yields of ＞ 3 mol/mol_(hexose) was achieved 5. Headspace CO_2 sequestration increased H_2 yield by 23% to 3.1 mol/mol_(hexose) & decreased buffer consumption 6. CO_2 sequestration had a significant impact on the microbial culture.
