Start-up and shock loading characteristics of a rotating biological contactor package plant
A full-scale rotating biological contactor treatment system primarily used for treatment of wastes from single-family dwellings was studied at the Blacksburg-Virginia Tech wastewater treatment plant. Municipal primary clarifier effluent was pumped into the 600 gpd rated RBC unit at the rate of 480 …

A STUDY OF THE MICROORGANISMS INHABITING ROTATING BIOLOGICAL CONTACTOR BIOFILMS DURING VARIOUS OPERATING CONDITIONS
<p>The microbial ecology of rotating biological contactors (RBC) is a combination of complex interrelationships among bacteria, protozoa, and metazoa and their perceived environment. Since very little information is available on the microorganisms inhabiting the biofilms, the major objective of …

Mathematical Modeling for Nitrogen Removal via a Nitritation: Anaerobic Ammonium Oxidation-Coupled Biofilm in a Hollow Fiber Membrane Bioreactor and a Rotating Biological Contactor
… anammox-coupled biofilm in a co-diffusion rotating biological contactor (RBC) were developed and implemented using AQUASIM. Four different start-up scenarios on the nitritation: anammox-coupled biofilm in an HFMBR were investigated. The supply of oxygen was simulated with the flow through …

Modeling effects of U-tube aeration in recirculating aquaculture systems
… of RAS component design, water quality, and biological processes on oxygen transfer requirements. A computer model was developed to simulate multi-component gas transfer and biological respiration in a pilot scale recirculating aquaculture system employing an u-tube aerator. Gas transfer …

A Comparative Analysis of Three Biofilter Types Treating Wastewater Produced in Recirculating Aquaculture Systems
… bead filter, packed tower trickling filter and a rotating biological contactor (RBC). After stocking, systems were allowed to acclimate using ammonia excreted by the yellow perch. Following acclimation, a comparative analysis on biofilter performance began. To evaluate filter performance, water …

Water chemistry characterization and component performance of a recirculating aquaculture system producing hybrid striped bass
… for both the multi-tube solids clarifier and rotating biological contactor (RBC). Water chemistry and water quality analysis included dissolved oxygen (DO), alkalinity, ions, carbonaceous biochemical oxygen demand (CBODS), chemical oxygen demand (COD), dissolved organic carbon (DOC), total …

Comparative Growth of All-Female Versus Mixed Sex Yellow Perch (Perca flavescens) in Recirculating Aquaculture Systems
… one of three different biofilter types: a rotating biological contactor, a trickling filter or a bead filter. The all-female fingerlings (S1) used were originally derived from Lake Mendota, Wisconsin. The mixed-sex fingerlings (S2) used were originally derived from Lake Erie. Temperature …
