The use of wood-polymer composites in a Moving Bed Biofilm Reactor Technology (Rapid Communication)

Abstract

Moving Bed Biofilm Reactor (MBBR) systems are increasingly used for municipal and industrial wastewater treatment. Innovative wastewater treatment technologies are developed to respond to changing regulatory requirements, increase efficiency, and enhance sustainability or to reduce capital or operating costs. Extensive research on how to use new materials in a moving bed technology is currently being carried out. An interesting solution in this area due to the large active surface (above 1200 m2/m3) for biofilm is employment of wood-polymer composites (WPC). The elements of moving bed made of WPCmay be an interesting option for treatment plants that are difficult to access, where the applied technology should be characterized by flexibility that is the ability to adapt the technology to the changing sewage flow, so as not to worsen the quality of treated wastewater.
