SBSEnviro - Model BF-22 -Random Media for MBBR Systems
The MBBR Media, or Moving Bed Biofilm Reactor system, represents a sophisticated wastewater treatment process that utilizes free-floating media to harbor active biological cells. This hybrid system simultaneously employs both attached and suspended growth treatment methods. The core component is the specially engineered floating media, which offers a large surface area for bacterial growth. These media elements are in continuous motion, driven by air bubbles from air diffusers, ensuring a uniform biological growth across the surface. The BF-22 Random Media is notable for its non-clogging and self-cleaning properties, tailored to enhance plant performance. Extensive pilot plant trials have shaped its design parameters, maintaining active surface area even after stabilization. Unlike conventional media, the BF-22 avoids common issues such as energy inefficiency and loss of effective area, resulting in reliable, consistent performance.
'Continuous Movement' of this carrier element is driven by air bubbles supplied inside the reactor by means on air diffusers.
BF-22 Random Media for MBBR media, is a 'Non Clog' & 'self cleaning' type, designed in view of various factors which influences the plant performance. Our pilot plant trials helped us on concluding the design parameters required with FBBR. Importantly thrust was given to maintain the same active surface area even after plant stabilization period. Many Moving Bed Biofilm Reactor designers given little importance to specific area lost over of period of time has led to failures of similar installations. Either the system consume large amount of energy (as they eventually use coarse bubble aeration system to flush out the entrapped bio solids inside the media) or uses excess media in-order to overcome the problems at 'lost area'.
BF-22 Random Media overcome the problems faced with conventional moving media available elsewhere.
SALIENT FEATURES OF BF-22 RANDOM MEDIA ARE AS BELOW :
- Void ratio of more than 90% ensures minimal or no clog of biomass inside the individual media element.
- Higher ratio of PSA/TSA (protected surface area / total surface area)ensures maximum active surface area for biological activity.
- Configuration of media permits lower air quantity by encouraging fine bubble diffused aeration system.
- Media configuration ensures thinner and active biofilm over it.
- Higher values of PSA/TSA ratio indicate lesser area is exposed for wear & tear. This ensures biomass utilizes complete surface area available
