background wastewaters with high salt content disturb the metabolic function of microorganisms causing plasmolysis or activity loss in microorganisms, so the efficiency of biological treatment of saline wastewater by conventional microorganisms will decrease. objectives this study aimed to find the outbreak of disorder in the biological wastewater treatment process and how much salt leads to lo...

results the results of this study showed that the release of soluble chemical oxygen demand (scod) in the supernatant and srf were in the range of 127.9-831 mg/l and 12.48-36.55 m/kg at 10 to 120 min ultrasonic contact time, respectively. in addition, ts and vs decreased from 57.98 and 56.31 to 52.69 and 49.87 mg/l, respectively. despite the significant reduction in the solids, there was no con...
