Reconsidering Rotating Biological Contactors
There are many domestic wastewater treatment processes in use today. Generally, they are all biological systems and they may be broadly categorized as either fixed film processes or suspended growth processes. During the 1970s and early 1980s, the rotating biological contactor process (RBC), a particularly efficient fixed film process, became popular. However, the primary manufacturer of RBCs i...
متن کاملA Scale-up Design Procedure for Rotating Biological Contactors
A scale-up design procedure, based on a new physical mass transfer (PMT) model, whichdescribes the performance, for aerobic rotating biological contactors (RBC’s) is developed. This scale-up procedure can be used to determine the disc surface area needed to prevent an oxygen limitation or to obtain a specific degree of treatment. In contrast to the empirical, and most previous RBC performance m...
متن کاملEffect of glutaraldehyde biocide on laboratory-scale rotating biological contactors and biocide efficacy
The effect of glutaraldehyde, a commercial biocide widely used in paper and pulp industry, on the performance of laboratory-scale rotating biological contactors (RBCs) as well as biocide efficacy was studied. Biofilms were established on the RBCs and then exposed to 0 180 ppm glutaraldehyde at a dilution rate of 1.60 h. The results showed that the biofilms became acclimated to glutaraldehyde an...
متن کاملMunicipal Wastewater Treatment With Rotating Biological Contactors A review of factors influencing the efficiency of RBCs
Rotating biological contactors (RBCs) constitute a very unique and superior alternative for biodegradable matter and nitrogen removal on account of their feasibility, simplicity of design and operation, low land area requirement, low energy consumption, low operating and maintenance cost and treatment efficiency. The present review of RBCs focus on parameters that affect performance like rotati...
متن کاملLow-ammonia niche of ammonia-oxidizing archaea in rotating biological contactors of a municipal wastewater treatment plant
The first step of nitrification is catalysed by both ammonia-oxidizing bacteria (AOB) and archaea (AOA), but physicochemical controls on the relative abundance and function of these two groups are not yet fully understood, especially in freshwater environments. This study investigated ammonia-oxidizing populations in nitrifying rotating biological contactors (RBCs) from a municipal wastewater t...
