Moving Bed Biofilm Reactor – A New Perspective in Wastewater Treatment

Abstract

A new advanced biological reactor for waste water treatment, Moving Bed Biofilm Reactor (MBBR) is discussed. General description of expected setup of reactor is given. The proposed results from different applications when used for domestic waste water will be discussed. Moving Bed technology presents several operational advantages, compared to other conventional biological treatments. Different applications of this technology for small plants will be studied, considering main investment and operating costs. Processes will take account of Moving Bed Biological Reactors (MBBR) with some sort of modifications. Conditions which may be studied will include COD removal, or COD and nutrients removal, with different primary treatments. Smaller biological reactor volumes and smaller secondary settling surface are needed. In conclusion, 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.
