MBR membrane module clogging article featured at thembrsite.com

Over the years our Technical Director Mr. Dennis Livingston and Professor Simon Judd have shared ideas on the challenges of membrane clogging in submerged/immersed membrane bioreactor (MBR) systems. The feature article, Clogging mitigation through MBR membrane module design, describes what MICRODYN NADIR® has done to address the problem.

In 2019, MICRODYN NADIR introduced the BIO-CEL® L-2 Membrane Module that is specifically designed to resist the effects of clogging. There are three unique design elements built into the L-2. First, the sides were taken off to prevent damage that can be caused by air channelling and to simplify maintenance. Second, a reinforcing bar was added to the top edge of each membrane sheet to prevent tears. And third, a shock-absorbing ring was added between the upper support rings.

According to data presented in the article the BIO-CEL® L-2 is 15-39 times more durable in terms of specific types of wear that can be caused by clogging and 14-24 times easier to service should clogging occur. The paper also includes performance information from full-scale plants that indicates a much higher resistance to clogging as compared to other FS and FP technologies.

About The MBR Site

The MBR Site is owned by Claire and Simon Judd (of Judd & Judd Ltd, trading as The MBR Site and Judd Water & Wastewater Consultants), based in Bedfordshire in the UK.

Launched in 2010, The MBR Site is now an established leading source of information and guidance for everyone interested in membrane bioreactors for water or wastewater treatment − practitioners, researchers and technology providers.

The L-2 module is backward compatible with select older Ovivo® and Microdyn Nadir® membrane modules. Using a mounting hardware (adapter) kit, L-2 modules can be used to quickly replace older module types. It generally takes less than 4 hours to replace one module. They are warehoused in Austin, TX and can be shipped in 3-5 business days. For emergency situations, new modules can be shipped with 72 hours. If needed, our team can provide inspection, repair and or installation services.
