Membrane Bioreactor Market Trends

Trends in the membrane bioreactor market show a rapid increase in the use of hollow fiber membranes and submerged MBR systems, as they provide the most spatial treatment efficiency and energy savings. Market players are creating value-added hybrid solutions for more stringent water quality standards, incorporating MBRs plus subsequent treatment processes like reverse osmosis or ultraviolet (UV) disinfection. There is also a push towards smart MBR solutions that can monitor system performance in real time and offer predictive proactive maintenance.

In the membrane bioreactor market, demand for containerized MBR systems is increasing for use at remote locations and temporary industrial applications. Utilities are further modernizing legacy infrastructure by retrofitting MBR systems to improve effluent quality and reduce sludge production.

Emerging Developments in the Membrane Bioreactor Market

In the membrane bioreactors market, there are manufacturers developing new membrane materials like graphene oxide and nanocomposites to help with permeability, anti-fouling rates, and life of membranes. As well, research is focused on biofilm-based MBRs (BF-MBRs) and anaerobic MBRs for further increasing energy efficiency and nutrient recovery.

There are also new developments relating to the incorporation of artificial intelligence (AI) and Internet of Things (IoT) function into MBR systems to enable automatic process control, energy optimization, and anomaly detection. Strategic partnerships are also continuing to expand between MBR manufacturers and EPC firms to provide global turnkey and scalable wastewater treatment project options.
