Analysis of the filterability in industrial MBRs. Influence of activated sludge parameters and constituents on filterability

► We analyzed the impact of constituents of industrial activated sludge on filterability. ► Permeability alone has demonstrated to be a weak parameter to monitor operation. ► Instead, filterability provides much more information to monitor MBR processes. ► The colloidal fraction demonstrated to impact the most the filterability. ► Process optimization in industrial MBRs is possible not only in an energy saving scheme.
