The membrane biological reactor (MBR) configuration has proven to be optimal for treatment of many industrial
wastewaters, especially when optimized treatment efficiencies are an important consideration. Ceramic MBR is being
consolidated as a reliable technology for industrial applications, due to the benefits of the system, while ceramic membranes
may be an adequate alternative for anaerobic MBR application, due to evidence of low membrane fouling rate and
the ability to rigorously clean their surface without at the same time reducing the effective membrane life. This review
summarizes Recent Patents on Engineering that disclose key data for both the functioning of MBRs and the use of ceramic
membranes. Specifically, an advanced control system for a membrane bioreactor wastewater treatment plant is disclosed,
while an integrated biological treatment coupled to membrane filtration is proposed for advanced nutrients removal
and reuse of treated waters. Recent studies have been focused on the production of a specific bioceramic membrane
with selective adsorption effects and simultaneous digestion ability. Bioceramic membranes may provide effective carbon
sources and required minerals to activated sludge microorganisms, while they can be used as biological media filter material
for air filtration and wastewater treatment. Furthermore, bioceramics may adsorb phosphate ions and remove oxygen
rich components such as nitrates from aqueous solutions.
