KONTAKT 500 from Raschig USA is lightweight, durable and efficient submerged bed media ideal for MBBR and integrated fixed film/activated sludge systems, or for replacement of media or carrier elements in existing systems. It can be added to aeration tanks and retained by a separation device. Diffused aeration systems and/or low-energy mechanical mixers usually achieve sufficient agitation of the media. Its design allows the media to freely move throughout the bioreactor and provides a high percentage of protected surface area for microorganisms to adhere to. In turn, this allows for an increase in the overall biomass concentration, which can reduce the tank volume required for wastewater treatment. Wastewater can pass freely through the large openings of the media, which helps maintain a healthy and thin biofilm. 540/862-8426; www.raschig-usa.com.
