Rotating biological contactor (RBC) is an attached-growth biological process, which consists of a series of rotating plastic media all coated with a layer of biofilm. The biofilm or slime on the media aerobically react with substances in a waste stream for bio-oxidation and nitrification, or anaerobically react with the substances for denitri-fication. This chapter discusses the theory, performance,...
Among the suspended-growth biological treatment processes covered in this chapter are conventional activated sludge, high rate activated sludge, pure oxygen activated sludge, contact stabilization, activated sludge with nitrification, separate stage nitrification, separate stage denitrification, extended aeration, oxidation ditch, Powdered Activated Carbon Treatment (PACT) process, carrier-activated...
In a conventional activated-sludge process, bio-oxidation, nitrification, and denitrification reactions occur in three separate bioreactors connected in series. Each bioreactor has its own type of micro-organisms (i.e., activated sludge), and each bioreactor has its own clarifier for micro-organisms—water separation. In a single sludge biological system, the mixed micro-organisms are used throughout...
Biological technologies can be used to treat a vast majority of organic wastewaters because all organics could be biologically degraded if the proper microbial communities are established, maintained, and controlled. Before environmental engineers design and operate biological treatment systems that create the environment necessary for the effective treatment of wastewater, a sound understanding of...
Membrane bioreactor (MBR) is a biochemical engineering process involving the use of both (a) a suspended growth bioreactor for biochemical reactions (such as fermentation, bio-oxidation, nitrification, and denitrification); and (b) a membrane separator for sequent solid–liquid separation. In a chemical engineering fermentation process, the solids may be yeasts and the liquid may be an alcohol. In...
Membrane bioreactor (MBR) is a biochemical engineering process involving the use of both (a) a suspended growth bioreactor for biochemical reactions (such as fermentation, bio-oxidation, nitrification, and denitrification) and (b) a membrane separator for subsequent solids–liquid separation. In a chemical engineering fermentation process, the solids may be yeasts and the liquid may be an alcohol....
