Wastewater is any water that is against the usage by human . Wastewater is the result of domestic, commercial, industrial or agricultural activities.
After the use water is returned to the environment in a different condition, usually as dirty water (wastewater).It is never returned in the same way as it was withdrawn. Wastewater produced by households or communities is also called municipal wastewater or sewage. (Tilley) Effluent refers to the sewage or liquid waste that is discharged into water bodies either from direct sources or from treatment plants. Influent refers to water, wastewater, or other liquid flowing into a reservoir, basin or treatment plant.

They all produce high volumes of wastewater.
Non-sewage: This is discharged by manufacturing processes and commercial enterprises. Process wastewater can contain rinse waters including such things as residual acids, plating metals, and toxic chemicals. Wastewater is also generated from agricultural facilities. Water used for cleaning in animal farms, washing harvested produce and cleaning farm equipment.
Pollutants
In wastewater pollutants like physical, chemical and biological pollutants, hazardous toxins which are dissolved, other particles, suspended matters and sediments of varying size at different concentration levels and composition are present.
Chemical or physical pollutants
• Heavy metals, including mercury, lead, and chromium
• Organic particles such as feces, hairs, food, vomit, paper fibres, plant material, humus, etc.;
• Soluble organic material such as urea, fruit sugars, soluble proteins, drugs, pharmaceuticals, …show more content…
In both cases the oxygen-consuming substances are mainly of organic origin. These substances should be reduced to a minimum in the wastewater treatment plant. Normally focus more on COD and municipalities more on BOD removal. With chemical treatment, removal of COD is improved at basically all kinds of wastewater plants. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a surrogate of the degree of organic pollution of water.
