biofilm support media, rotating biological contactors (RBCs), purification.
Abstract
Rotating Biological Contactors (RBCs) are an
exclusive option for removing biodegradable materials and nitrogen due to their viability, ease of design and operation, quick startup, low need for land area, low energy consumption, low operating and maintenance costs, and treatment effectiveness. Emphasis on performance-affecting factors like rotational speed, organic and hydraulic loading rates, retention time, biofilm support media, staging, temperature, influent wastewater characteristics, biofilm characteristics, dissolved oxygen levels, effluent and solid recirculation, step-feeding, and medium submergence. There are also reports of operating issues, scale-up and design considerations, and comparisons with other wastewater treatment systems for RBCs. Microorganisms flourish on the disc's surface, where the biological breakdown of wastewater contaminants occurs. Increasing organic load can be handled by rotating biological contactors (RBCs). Microorganisms must have access to both oxygen and food for survival and growth. The rotating discs draw oxygen from the atmosphere. Growing microorganisms accumulate on the media until shear pressures from revolving sewage discs cause them to be sloughed off. The sloughed biological solids in suspension settle as sludge after being processed through a clarifier with the RBC's effluent.
