Cover Story: Particulate organic carbon recovered from sewage sludge within a wastewater treatment plant is an underutilized carbon source. The possibility of generating precursors such as short-chain fatty acids (SCFAs) via hydrolysis have been explored, however, the high solid concentration alongside these SCFAs can impede resource recovery. In this study, hydrolyzed sludge with SCFAs (or hydrolyzate) is treated via filter-press and cross-flow microfiltration. Hydroxypropyl trimethyl ammonium starch (HPAS) is used for conditioning the hydrolyzate prior to the filter press. Although HPAS aids in solid removal, it passes through the pores of the filter press and electrostatically interacts with the microfiltration membrane. Backwashing or inducing a positive charge on the membrane can reduce such HPAS interaction. View this paper
