Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle . Once back in the water cycle, the effluent creates an acceptable impact on the environment.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
Adsorption/bio-oxidation process is a part of innovative wastewater treatment concept WaterSchoon, realized in the Netherlands. 250 apartments in the new district Noorderhoek (Sneek, the Netherlands) are equipped with separate collection systems for toilet wastewater and the rest of the household wastewater (or so-called greywater). Both ...
Treatment in urbanized areas is typically handled by centralized treatment systems. Alternative systems may use composting processes or processes that separate solid materials by settlement and then convert soluble contaminants into biological sludge and into gases such as carbon dioxide or methane .

A goal of the wastewater purification by means of AOP procedures is the reduction of the chemical contaminants [7] and the toxicity to such an extent that the cleaned wastewater may be reintroduced [8] into receiving streams or, at least, into a conventional sewage treatment.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
Secondary treatment can reduce organic matter (measured as biological oxygen demand) from sewage, using aerobic or anaerobic biological processes. A so-called quarternary treatment step (sometimes referred to as advanced treatment) can also be added for the removal of organic micropollutants, such as pharmaceuticals. This has been implemented ...
