Following the motto “creativity has no limits” both companies have analyzed and reconsidered their products and have set a new milestone in MBR technology: The goal was to jointly develop the largest MBR module available on the market which carries the unique membrane laminate technology by MICRODYN-NADIR and at the same time is a rotating system. In practice this results in lower operating and investment costs as well as an increase in reliability and packing density.
“By combining our two technologies we have created a groundbreaking product symbiosis”, says Walter Lamparter, CEO at MICRODYN-NADIR, “I am confident that this will set new standards!”
The VRM ® system by HUBER is a rotating membrane system. The membrane modules are submerged into the activated sludge and are mounted segmentally onto air tubes. The trapezoidal membrane segments are rotated through an air induced flushing stream driven by a filter drive. The rising air bubbles are continuously cleaning the membrane laminate sheets. The cover layer in the interstices of the laminate sheets is removed reliably and therefore fouling can significantly be reduced. Other than that, the energy demand is minimized at the same time.
The trapezoidal membrane segments are bringing the proven BIO-CEL ® technology into play. This state-of-the-art technology was developed by MICRODYN-NADIR – the membrane and module supplier from Wiesbaden. Instead of equipping the trapezoidal segments with a NADIR ® flat sheet membrane welded onto a plate as before, HUBER is now putting their trust into the membrane laminate technology based on NADIR ® flat sheet membrane made by MICRODYN-NADIR.
“We are convinced of the sophisticated and unique membrane laminate technology”, says Dr. Oliver Rong, vice CEO at HUBER SE. “We have screened the market over the past years and found MICRODYN-NADIR´s laminate technology to be the most reliable and innovative solution for wastewater treatment with membrane bioreactors available on the market. We want to offer the best product to our customers which is what brought us to the idea of the next generation of our VRM ® membrane systems. By combining our VRM ® technology with the unique laminate technology we achieve a significantly higher packing density and therefore an increase in membrane area per module. Moreover, energy demand and costs can be reduced tremendously.”
MICRODYN-NADIR´s membrane laminate technology is unique – it is the smart combination of the best of two technologies. Not a hollow fiber and not a plate but a hollow sheet! Unlike a plate and frame construction the BIO-CEL ® is backwashable like a hollow fiber module and at the same time problems such as fiber clogging cannot occur. Moreover, the BIO-CEL ® is the only module design that can be cleaned mechanically. The smart Mechanical Cleaning Process (MCP) minimizes chemical demand or even makes the use of chemicals unnecessary! This saves cost, minimizes downtime due to required intensive cleanings and keeps the permeability stable. In addition, the BIO-CEL ® membrane laminate technology is equipped with a self-healing mechanism which allows the laminate to „heal“ itself in less than 2 minutes. This results in constantly high effluent qualities even in case of damages caused to the membrane.
The official launch of the new technology will take place on Monday May, 30 at 3 p.m. at the HUBER booth in hall A2, booth no. 351 . We are looking forward to your visit. MICRODYN-NADIR is also present with its own booth in hall A2, booth no. 227 .
