Highly charged EDTA was investigated as a draw solution in AGB-OsMBR/MD hybrid system.

Low salt accumulation (<1.5 g/L) was observed during a 60-day AGB-OsMBR operation.

AGB integrated with an OsMBR system could reduce membrane fouling of FO membrane.

AGB-OsMBR achieved high nutrient removal (99.94% of NH₄-N and 99.73% of PO₄-P).

Diluted draw solution could be effectively recovered (100%) by PTFE MD membrane.
