 Chemical free cleaning of MBR wastewater treatment plants Chemical free cleaning of MBR wastewater treatment plants
MICRODYN-NADIR GmbH located in Wiesbaden, Germany and Darmstadt University of Technology have developed a new, environmentally friendly cleaning process for submerged membranes in membrane-bio-reactor (MBR) applications.
MICRODYN-NADIR GmbH located in Wiesbaden, Germany and Darmstadt University of Technology have developed a new, environmentally friendly cleaning process for submerged membranes in membrane-bio-reactor (MBR) applications.
Due to their small footprint and superior effluent quality, MBR plants are the next generation of biological wastewater treatment. The driving force for this technology is the request for cleaner, more environmentally friendly cleaning of the membrane modules. In 2005, MICRODYN-NADIR developed the first back washable flat sheet membrane. This only requires a simple pre-treatment of the feed flow and exhibits extended operation between cleaning cycles. However, even with this novel development, some chemicals are needed for intensive cleaning.
A newly developed mechanical cleaning process (BIO-CEL®-MCP) utilizing granulates can now be integrated to the MBR. This allows for a chemical free operation and even more importantly a significant enhancement of flux. The usage of the MCP is even suitable for external membrane cleaning of the fouled membranes in any condition. In terms of sustainability with this cleaning process the environment can be protected (no usage of chemicals and therefore no chemical by-products). Additionally the cost can be reduced. New Generation New Generation
New generation of submerged BIO-CEL®-Modules
MICRODYN-NADIR, one of the world’s leading independent membrane and filter module producers, now introduces the new submerged BIO-CEL®-Module for Membrane Bio Reactors (MBR) as a cassette system. This new design includes the membrane cassettes and the frame that holds them.
With this innovation the installation and the maintenance of the module is much easier. For the first time the aeration and the frame support are independent of the membrane unit. This is an important advantage, especially for larger plants, in that it makes exchanging portions of the membranes simple to perform.
The BIO-CEL® modules have been available since the end of 2005 and are rapidly being implemented worldwide. The unique advantage of the new MICRODYN-NADIR MBR-module is the continuation of a open plate system to avoid braiding and sludge deposition and it is possible to back flush the module, maintaining high throughput.
The BIO-CEL ® module BC 400 will be displayed for the first time at the IFAT fair in Munich. This new flat sheet device which is a size unobtainable for all existing plate and frame systems enable MICRODYN-NADIR to deliver a new size of modules especially for larger systems.
The membrane area of this device is 400 m². With the packaging density comparable to hollow fiber modules, it is possible to incorporate large membrane surface areas into smaller footprints.
Vision
Our Vision is to become the leading global independent Membrane and Module supplier.
