The German river association Erftverband has been into MBRs for municipal wastewater treatment for more than a decade, installing the first such system in Germany and commissioning what was the largest membrane bioreactor in the world.Read article
Membrane bioreactors, and specifically those treating municipal wastewater, are subject to ‘ragging’. When the membrane module is removed, characteristic thick strands of material can be seen hanging from the bottom of the module.Read article
In October 2009, we received a list of what was thought to be the 20 largest MBRs in the world at that time. The peak daily flow capacities on that list ranged from 30 to 100 MLD, with the total capacity being just over 1,000 MLD.Read article
A number of factors have been instrumental in the acceptance of MBR technology in the wastewater industry as an alternative to traditional conventional treatment systems. Victoria Kippax explains the MemPulse MBR system.Read article
MBRs are growing in size and number, reflecting a growing confidence in the technology. The number of MBR membrane module products is currently increasing by 3−5 a year, and the market itself is growing exponentially at a rate between 11.5 and 13%.Read article
