Moving Bed Biofilm Reactor � New Innovation in the Field of Conventional Biological Wastewater Treatment

Gulhane M. L, Kotangale A. J

Abstract :

A new advanced biological reactor called Moving Bed Biofilm Reactor (MBBR) for wastewater treatment is discussed. General description of expected setup of reactor is given. The Moving Bed Biofilm Reactor (MBBR) technology is an attached growth biological treatment process based on a continuously operating, non-clogging biofilm reactor with low head loss, a high specific Biofilm surface area, and no requirement for backwashing. MBBR is often designed as aerobic system. Moving Bed technology presents several operational advantages, compared to other conventional biological treatments. Different applications of this technology for small plants are studied, considering main investment and operating costs. Processes will take account of Moving Bed Biological Reactors (MBBR) with some sort of modifications. Conditions studied include COD removal, or COD and nutrients removal, with different primary treatments. Smaller biological reactor volumes and smaller secondary settling surface are needed. The results can indicate that MBBR with polyethylene media as Biofilm carrier may possess great potential to be used for OMs removal from water and wastewater. This study can be helpful to check possibility that the moving bed Biofilm process may be used as an ideal and efficient option for the total nutrient removal from municipal wastewater
