Effluent is wastewater from sewers or industrial outfalls that flows directly into surface waters, either untreated or after being treated at a facility. [1] The term has slightly different meanings in certain contexts, and may contain various pollutants depending on the source.
However, for many rivers in the proximity of humans, the largest input is from sewage whether treated or untreated. The nitrogen derives from breakdown products of proteins found in urine and faeces. These products, being very soluble, often pass through sewage treatment process and are discharged into rivers as a component of sewage treatment ...
A losing stream, disappearing stream, influent stream or sinking river is a stream or river that loses water as it flows downstream. The water infiltrates into the ground recharging the local groundwater , because the water table is below the bottom of the stream channel.
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. It is also possible to reuse it. This process is called water reclamation. [1] The treatment process takes place in a wastewater treatment plant.
Effluent pumping systems have pipes that are buried at a constant depth, such as a metre and a half, and rely on pumping stations that create pressure to move the waste to a treatment facility. An effluent sewer that uses gravity may be called a septic tank effluent gravity (STEG) system, while a pumping system may be called a septic tank ...
After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens). Waste stabilization ponds involve natural treatment processes which take time because removal rates are slow.
This is because the composition of any wastewater stream is different. As an example an effluent consisting of a solution of simple sugars that might discharge from a confectionery factory is likely to have organic components that degrade very quickly. In such a case, the 5 day BOD and the ultimate BOD would be very similar since there would be ...

A stream is a continuous body of surface water [1] flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a ...
