Rotating Biological Contactors (RBCs) Biofilter design must take into account all of the stated water-quality management criteria, as well as considerations of space and cost efficiency. A rotating biological contactor or biodisc filter is a fixed film bioreactor composed of circular plates aligned on.
model of two-stage Rotating Biological Contactor (RBC), with a provision to vary the speed of rotating blades. Grey wastewater was used to study the performance of the modified rotating biological contactor. The reactor consisted of four rotating blades in.
During the ’s, Rotating Biological Contactors (RBCs) gained popularity as a biological treatment process alternative to Trickling Filters. New developments in plastic media material, as well as smaller energy requirements compared to activated sludge processes, led to the construction of numerous RBC plants during the s.
The performance of a Rotating Biological Contactor (RBC) was studied at a loading rate of gallon/ft. 2/day. The BOD5 of domestic wastewater was reduced from mg/R to 3 mg/n, a reduction Of 98%.
The total suspended solids were reduced from 73 mg/2, to 32 mg/L and ammonia was completely oxidized to nitrate. The economics. biological treatment systems as well as other fixed film systems due to lower organic loading per mass of biological solids, longer solids detention time, and better control of short circuiting.” (emphasis added) United States Environmental Protection Agency () Rotating Biological Contactors, EPA//S/, Washington.
According to the EPA drinking and waste water plants use % of energy used in the U.S.

This paper describes a design of an industrial-scale rotating biological contactor (RBC) and its performance installed in recirculating aquaculture system culturing tilapia at El-Nenaeia Fish Farm.
A rotating biological contactor (RBC) is a successful wastewater Address: Department of civil Engineering, Faculty of civil Engineering, AL-Qadisyia University, Iraq USE OF AROTATING BIOLOGICAL CONTACTOR FOR APPROPRIATE TECHNOLOGY 3 Consider an infinitesimal volume in a biofilm reactor, by the mass.
The Rotating Biological Contactors (RBCs) or simply “biodiscs” are part of the so-called biofilm processes. In these reactors, biofilm support material consist of discs, with a certain uniform distance between each other, coupled to a rotating horizontal shaft driven by a motor.
In general, the shaft is installed above water surface level. Rotating biological contactors (RBC) are a conventional aerobic biological wastewater treatment unit. Conventional biological treatment means activated sludge systems and fixed film systems such as trickling filters, or RBC (NOLDE ).
The advantage of all these systems is that they are compact (i.e. in densely populated urban settings) and that they efficiently reduce organic matter. A rotating biological contactor or RBC is a biological fixed-film treatment process used in the treatment of wastewater following primary treatment.
The primary treatment process involves removal of grit, sand and coarse suspended material through a screening process, followed by settling of suspended RBC process allows the wastewater to come in contact with a biological film in.
The rotating biological contactors are fixed film moving bed aerobic treatment processes, which able to sustain shock loadings.

The Rotating Biological Contactor (RBC) is a fixed film biological secondary treatment operation, a media, consisting of a series of circular disks mounted side by side on a common shaft is rotated through the waste-water flow. Rotating Biological Contactors are an efficient fixed-film wastewater technology for secondary and/or advanced biological treatment.

Loading bid history. 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.

Brazil* USDA-Agricultural Research Service, National Center for Cool and Cold Water Aquaculture, Kearneysville, WVUSA. Photographs of an RBC unit and its square shaft detail are shown in Figs 1 and 2.
HISTORICAL REVIEW A review of Rotating Biological Contactor (RBC) technology from to was undertaken. In total, 93 references were collected and indexed. Much of the research concerning RBC technology was conducted by the manufacturers themselves.
The evaluation of the scaled-up model with a capacity of L containing 52 polyurethane discs rotating at 6 rpm was done on-site at Distell, Stellenbosch in The wastewater from the cellar that flows into an open holding tank had the stems and some of the skins removed.

Water & Wastewater Treatment. The advantages of using rotating biological contactors (RBC) in wastewater treatment plants outweigh the disadvantages of installing and operating the system.
Rotating biological contactor systems have been hit by a number of construction and operating problems, including the failure of the equipment used to treat.EnviroDisc Rotating Biological Contactors (RBC) provide highly efficient fixed film BOD and ammonia removal with low energy usage and maintenance requirements.
In the RBC process, wastewater flows through shallow tanks containing the partially submerged, rotating shafts where biomass is carried on the media for reduction of pollutants.A rotating biological contactor or RBC is a biological treatment process used in the treatment of wastewater following primary treatment.
The primary treatment process removes the grit and other solids through a screening process followed by a period of settlement. The RBC process involves allowing the wastewater to come in contact with a biological medium in order to remove pollutants in the.
