Advanced control system for optimal filtration in submerged anaerobic MBRs (SAnMBRs)

► An advanced control system for optimal filtration in SAnMBRs has been developed. ► The controller was validated using industrial-scale hollow-fibre membranes. ► The gas sparging intensity and the frequency of physical cleaning were regulated. ► The fouling rate was low by applying sustainable SGDm (approx. 0.23 Nm3 h−1 m−2). ► Low downtimes for physical cleaning (less than 2% of operating time) were achieved.
