A Comparison of the Physical, Chemical, and Biological Properties of Sludges from a Complete‐Mix Activated Sludge Reactor and a Submerged Membrane Bioreactor
The properties of sludges from a pilot‐scale submerged membrane bioreactor (SMBR) and two bench‐scale complete‐mix, activated sludge (CMAS) reactors treating municipal primary effluent were determined. Compared with the CMAS sludges, the SMBR sludge contained a higher amount of soluble microbial products (SMP) and colloidal material attributed to the use of a membrane for solid–liquid separation; a higher amount nocardioform bacteria, resulting from efficient foam trapping; and a lower amount of extracellular polymeric substances (EPS), possibly because there was no selective pressure for the sludge to settle. High aeration rates in both the CMAS and SMBR reactors produced sludges with higher numbers of smaller particles. Normalized capillary suction time values for the SMBR sludge were lower than for the CMAS sludges, possibly because of its lower EPS content.
