RBC means Rotating Biological Contactor
RBC is an attached Growth Process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the waste water.
Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes place.

Which wastewater treatment process produces BOD-containing effluent used for irrigation?
secondary sewage treatment
What are the advanced waste water treatment processes?
The three stages of sewage treatment are primary, secondary, and tertiary treatment. Primary treatment involves physical processes to remove large solids and debris. Secondary treatment uses biological processes to break down organic matter. Tertiary treatment involves advanced processes to remove any remaining contaminants before the treated water is released back into the environment.
What is secondary waste treatment?
Primary sewage treatment essentially removes the lumps from raw sewage by settling and some of the organics by holding the waste before discharge. Secondary treatment de-lumps and then removes organics by allowing bacteria to feed on the nutrients then removing/collecting the bacteria for disposal. Tertiary treatment filters or chlorinates the treated waste to remove smaller particulates and bacteria.
How do the microorganisms help in sewage treatment?
Sewage treatment plants use microorganisms to destroy the biological material in sewage.

When solid waste produced by a sewage-treatment plant is called .?
The solid wastes from a sewage treatment system are determined by the degree of treatment provided:Septic tanks: Organ sludge composed of fecal matterPrimary treatment systems: Mainly settled fecal matterSecondary treatment: Solid materials collected at the intake, aerobic sludges from aeration ponds, anaerobic sludges from digestersTertiary treatment: same as secondary treatment.
What is sewage and how is it treated?
Sewage is liquid waste from households and retail areas that contains sanitary waste (Feces and urine), soaps, food scraps, water, cooking wastes etc.It is gathered and piped to sewage treatment plants. Depending on the complexity of the plant the treatment consists of:* Primary treatment: "De-lumping" the sewage and allowing the fluids to sit in lagoons for a period of time before discharge. Removed solids are disposed of to land.* Secondary Treatment: "Delumping" the sewage. Allowing the sewage to be mixed with bacteria in aeration basins which remove the dissolved organics. Removing the bacteria and discharging the treated water. Removed solids are disposed of to the land or anaerobically digested to generate methane. * Tertiary Treatment: The same as Secondary Treatment but the effluent is filtered and disinfected before discharge Storm water can also be considered as sewage. In many cases it has as many contaminants as sanitary sewage. I is generally simply settled prior to discharge to allow solids to settle out and oils to float to the top for removal

How does a sewage treatment plant work?
the sewage plant works by having a primary treatment that help take out all of the excess oil and trash that goes into it then comes the secondary treatment that they put chloride in it to kill all the bacteria or another way putting it into a zone layer which acts like a dienfactant torwards bacteria and last it might be transffered to the river, lake, or stream and after that it goes to your homes!
What are the downsides of living near a sewage treatment plant?
Sewage treatment is an essential process in a more advanced society. Untreated sewage can reenter the water system and spread disease. Land around a sewage treatment plant would be cheap, as it is a less desirable area to live, because of the bad smell.
