The aim of this study was to investigate the effect of low temperature pretreatment on the anaerobic digestion of microalgal biomass grown in wastewater. To this end, microalgae were pretreated at low temperatures (55, 75 and 95°C) for 5, 10 and 15h. Biomass solubilisation was enhanced with the pretreatment temperature and exposure time up to 10h. The methane yield was improved by 14%, 53% and 62%...
Biogas is a renewable primary energy source. The aim of the current study was to quantify the effect of temperature and feedstock size on biogas production of water hyacinth used for phytoremediation of rural domestic wastewater using anaerobic digestion (AD) process on a batch scale. This experiment consisted of two factors: AD temperature (mesophilic, 35°C) and thermophilic (55°C) and feedstock...
The effect of hydraulic retention time (HRT) on the performance of hydrogen production from beet sugar wastewater by anaerobic fermentation using mixed microbial communities was investigated in a continuous stirred-tank reactor (CSTR) in this present study. A CSTR was designed and its performance was determined at various HRT. The goal was to find the optimal HRT for hydrogen production, to minimize...
The Purpose of this work was to explore upgrade of UASB(Up-flow Anaerobic Sludge Bed)technology, that has been proved inefficient in dealing with high strength organic content wastewater (COD concentration: 20,000-150,000 mg·l-1) from distillery plants that use cane molasses and cassava as feedstocks in GuangXi Region, China, where sugar and cassava starch are two pillar industries. The limits of...
