An enhanced anaerobic membrane bioreactor treating bamboo industry wastewater by bamboo charcoal addition: Performance and microbial community analysis

Effects of Solids Retention Time on the Anaerobic Membrane Bioreactor with Yttria-Based Ceramic Membrane Treating Domestic Wastewater at Ambient Temperature

“…As depicted by Figure S4, the flux level has decreased with decreasing SRT, which is related to the increase of SMP and EPS. The reuniting of granular particles can occur at high EPS levels, which increases the particle size [51]. This phenomenon has been effectively confirmed by EPS, SMP, and sludge PSD results in the present study at 25 days of SRT.…”

“…The dominant peaks in the influent and effluent samples in all three SRT stages were in region I and region IV substances, indicating the presence of tyrosine-like proteins and SMPs in the bound EPS of the anaerobic sludge region I, II, and IV substances, which were the dominant substances in all SRT stages, while the As depicted by Figure S4, the flux level has decreased with decreasing SRT, which is related to the increase of SMP and EPS. The reuniting of granular particles can occur at high EPS levels, which increases the particle size [51]. This phenomenon has been effectively confirmed by EPS, SMP, and sludge PSD results in the present study at 25 days of SRT.…”

Effect of magnetic powder on membrane fouling mitigation and microbial community/composition in membrane bioreactors (MBRs) for municipal wastewater treatment

“…Baygi et al (2016) reported that concurrent KMnO 4 oxidation and polyelectrolyte flocculation could increase the sludge particle size, reduce the soluble microbial product (SMP) concentration and alleviate the biofilm layer resistance. Xia et al (2016) found that added bamboo charcoal (BC) prolonged operating time by decreasing SMP concentration and reducing membrane resistance. Deng et al (2014) developed a sponge-submerged membrane bioreactor (SSMBR) that maintained trans-membrane pressure (TMP) at 2.0 kPa over a period of 90 days by: firstly, depressing the bound extracellular polymeric substances (EPS) concentration; and secondly, improving the particle size, zeta potential and relative hydrophobicity of sludge floc.…”

Molecular identification of bamboo genera and species based on RAPD-RFLP markers

“…Most of the species richness is found in Pacific Asia and South America (Bystriakova et al 2003;Das et al 2008). Bamboos are used for a wide range of applications such as for umbrella handles, fishing rods, mud huts, mats, baskets (Bystriakova et al 2003), concrete reinforcement (Ghavami 2005), building material for supporting structures (Van der Lugt et al 2006), charcoal preparation (Xiong et al 2014;Xia et al 2016), cellulose extraction (Li et al 2015), hybrid microfibers fabrication (Yu et al 2014), and forages for maintaining environmental conditions (Panizzo et al 2016). Due to their fast growth rate (5-7 years to mature) and some potential fuel characteristics, e.g., low ash content, alkali index or heating value, they might also be a valuable resource for energy (Bystriakova et al 2003).…”
