Coaggregation of bacterial communities in aerobic granulation and its application on the biodegradation of sulfolane

Effects of carbon to nitrogen ratio on the performance and stability of aerobic granular sludge

“…The aerobic granulation is a self-immobilization process in which the loose biomass is converted into high-density compacted granule [1][2][3][4]. The aerobic granular sludge (AGS), compared to traditional activated sludge, has more excellent characteristics in terms of regular shape and compact structure, sedimentation, biomass accumulation, resistance to toxic compounds and high organic load, and removal efficiency of nutrient salts [5][6][7][8].…”

Hazardous wastes treatment technologies

“…Yang, Liu, Su, et al (2019) reported that a specific bacterial consortia from a monitoring well could effectively remove sulfolane and benzene at DO concentration of >1 mg/L, and a C:N:P ratio of 100:10:1 enhanced the degradation of sulfolane and benzene. Khan, Yu, Tay, and Achari (2019) used two methods to develop sulfolane degrading aerobic granules (SDAG): adaption of pregrown granules to the environment containing sulfolane and co‐aggregation with a bacterial culture native to the site contaminated with sulfolane. The first method took a longer time to start.…”

Integration of aerobic granulation and UV/H2O2 processes in a continuous flow system for the degradation of sulfolane in contaminated water

“…10 Consequently, in our previous study coaggregation of indigenous microbes from sulfolane contaminated site with aerobic granules generated stable robust granules that were able to degrade sulfolane effectively. 11 This technology is ideal for application because it benefits from having a consortium of millions of microorganisms harboring within a single granule with the potential to treat the most recalcitrant contaminants present in wastewaters. 12 On the other hand, one of the first in-depth AOP studies on treatment of sulfolane in aqueous medium was conducted by Yu et al, who reported the combination of UVC/ H 2 O 2 , UVC/O 3 /H 2 O 2 and UVC/O 3 to have significant effect on sulfolane degradation.…”

“…Aerobic granules used in this study were cultivated as described in our previous work. 11 A schematic of the continuous operation of integrated aerobic granulation and UV/H 2 O 2 processes is presented in Fig. 1.…”
