Thermophilic aerobic treatment systems offer unique advantages for treatment of high strength organic waste streams and slurries/sludges. These systems combine the best features of conventional aerobic and anaerobic processes that include rapid biodegradation kinetics and low biological solids production, respectively. Application of these processes can result in substantial economic benefit by reducing residuals processing and disposal costs. These systems have not been widely applied for industrial waste treatment, therefore the goal of this paper to show the advantages of applying thermophilic aerobic treatment to these streams. Also included in the paper is a discussion of the process benefits along with design/application considerations and industrial case histories.
Intracellular carbon flow in enhanced biological phosphorus accumulating cultures was tracked by using radiolabelled glucose and acetate as substrates. Batch studies using the labelled substrates verified that acetate and glucose were metabolized differently and acetate would be a more effective source of organic material for carbon supplementation. The use of acetate ensures that the greatest percentage of added carbon will be sequestered by phosphorus accumulating species. Carbon flow was also evaluated in bench-scale SBR system by wet chemistry methods to correlate the findings of the batch studies with that of the long-term carbon profiles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
