“…The ineffectiveness of physical membrane cleaning methods in this regard can be attributed to the formation of a rather compact cake layer or the development of biofilms and the deposition of biopolymers (such as extracellular polymers (EPS)) that are not easily separable by gas sparging or backwashing [50]. However, the sudden increase in TMP (Figure 5c) after day 45 could be a combined synergistic effect of a collection of medium-term characteristics and cake layer collapse and compaction [51][52][53].…”

Acidogenic fermentation of chicken manure (CM) for production and recovery of volatile fatty acids (VFA) is an interesting biological waste-to-value approach compared to benchmark organic waste management strategies. Considering the wide range of high value applications of VFA, a semi-continuous immersed anaerobic membrane bioreactor (AnMBR) was applied to boost VFA productivity and yield, while reducing downstream processing stages assisting the recovery of VFA. In this regard, the effect of parameters such as pH and organic loading rates (OLR) on the overall bioconversion and filtration performance was investigated. Thermal-shocked CM was applied both as inoculum and substrate. A very high VFA yield (0.90 g-VFA/g-VS) was obtained in the treatment with no pH control (~8.2) at an OLR of 2 g-VS/(L·d), presenting 24% higher yield compared to that of the controlled pH. Batch assays further demonstrated the enhanced hydrolysis and acidogenesis activities at weak alkaline conditions. A long-term (78 days) fermentation and filtration was successfully performed, where stable membrane filtration performance was experienced for about 50 days under high-solid (suspended solid of 37–45 g/L) and high flux (20 L/(m2·h)) conditions. Results suggest that AnMBR of CM is a feasible and promising process for VFA production and recovery.

“…With the current operation, the pressure rises quickly, resulting a frequent replacement of the 10um folding filter elements, which process requires about 24h, and the conductivity of the DTRO concentrated water is about 25 ms/cm. Notibaly, the membrane flux can be restored by a conventional "alkali washing + pickling" method on site [1,2]. Alkaline washing has proven to be highly effective in recovering the processing membrane, indicating that organic colloids are the main byproduct of the DTRO process and can easily clogged the membrane thus affect the treatment efficacy [3,4].…”

This experiment involved membrane pollution cycle experiments to identify the optimal pretreatment method, which was found to be raw water combined with PAC, effectively reducing membrane fouling. Following pretreatment, the first-stage recovery rate reaches 80%, the chemical cleaning cycle spans approximately 90 hours, and the conductivity of the concentrated water ranges between 35 ms/cm and 40 ms/cm.
