Results show that the mature algal-bacterial AGS with less filamentous could maintain its good settleability with sludge volume index below 41 mL/g when wastewater salinity was increased to 3%, in which loosely bound extracellular polymeric substances might play an important role. Under this condition, the granule system achieved slightly lower dissolved organic carbon removal (from 97% to 94%), while the removals of ammonia nitrogen, total nitrogen and total phosphorus were remarkably decreased from ~100%, 66% and 70% to 23%, 16% and 38%, respectively. However, the organics and nutrients removals could be recovered immediately when the salinity disturbance was removed from the influent. P bioavailability, on the other hand, kept almost stable (93–97%) in the AGS during the examination period. © 2020 Elsevier LtdAlgal-bacterial aerobic granular sludge; Granule stability; Nutrients accumulation; Nutrients removal; Salinity disturbance[SDGs]SDG6Ammonia; Biochemistry; Granular materials; Granulation; Nitrogen; Nutrients; Organic carbon; Recovery; Aerobic granular sludges; Dissolved organic carbon; Extra-cellular polymeric substances; Influent wastewaters; Nutrients removal; Sludge volume index; Total phosphorus; Wastewater salinity; Nitrogen removal; ammonia; nitrogen; organic carbon; phosphorus; alga; ammonia; bacterium; dissolved organic carbon; nitrogen; pollutant removal; polymer; wastewater; aerobic granular sludge; alga; algal growth; Article; bacterium; biomass; effluent; fractionation; nitrification; nonhuman; nutrient; osmotic pressure; polymerization; priority journal; salinity; salt stress; waste water management; wastewater; aerobic metabolism; bioreactor; salinity; sewage; waste water; Bacteria (microorganisms); Aerobiosis; Bioreactors; Nitrogen; Nutrients; Salinity; Sewage; Waste Disposal, Fluid; Waste Waterjournal article10.1016/j.biortech.2020.124492333166982-s2.0-85097801795
