Impacts of transient salinity shock loads on Anammox process performance

Effects of salinity on performance, extracellular polymeric substances and microbial community of an aerobic granular sequencing batch reactor

“…9e, the filamentous bacteria in the granular interior were also dominant at 8% salinity. Ma et al [36] reported similar result that the granular surface promoted the growth of many bacilli and filamentous bacteria after the shock of 60 g L À1 NaCl in the influent. Li et al [9] found that filamentous microorganisms could grow in compact granular structure with 5% NaCl in the substrate.…”

Anaerobic ammonium oxidation (anammox) under realistic seasonal temperature variations: Characteristics of biogranules and process performance

“…The zone settling velocity (ZSV) of the sludge was measured by recording the time for individual granules (more than sixty granules selected from the reactor randomly) to drop from a certain height in a measuring cylinder (Shen et al, 2012). For EPS extraction, the 'heating' method described by Ma (2012) …”

Enhancement of anammox activity by addition of compatible solutes at high salinity conditions

“…However, the widespread application of anammox process is limited by long start-up period, the low temperature, the presence of organic matters, high salinity and other inhibitors. The high salt in saline wastewater originated from many industries can induce cell plasmolysis or death due to the dramatic increase in osmotic pressure and thus may alter biochemical properties of activated sludge or the microbial community structure (Ma et al, 2012).…”
