- “An expanded granular sludge bed reactor (EGSB) was employed to evaluate the start-up process of fermentative biohydrogen production from compost leachate.”1
Researchers from the School of Environment and Chemical Engineering, Shanghai University, in Shanghai, China; have presented an article titled: “Start-up of EGSB for biohydrogen production from compost leachate.”
The researchers from Shanghai have also noted:
- “The removal performance of COD, total nitrogen, total phosphorus in leachate as well as the hydrogen production ability of EGSB was investigated.”
- “The results showed that at 35 degrees C +/- 1 degrees C, organic loading rate of 1.4-16.7 g/(L x d), the main pH of 5.0 to 5.5, the continuous hydrogen production by EGSB reactor using the compost leachate as substrate could be achieved after 20d’s acclimatization.”
- “Under conditions of HRT of 30 h and liquid flow rate of 3.0 m/h, the COD removal rate of between 50% to 70%, the content of hydrogen in the biogas of between 19%-33%, the maximal hydrogen production rate of 1 460 mL/(L x d), total phosphorus and total nitrogen removal rate of between 40%-70% and 32%-65% respectively, were achieved.
- “The total ethanol and acetic acid content was more than 80% in liquid end products (VFAs), suggesting the main fermentation is ethanol fermentation type.”
