    • Abstract:
      Sewage engineering is the discipline of civil engineering that addresses the separation, decontamination, and disposal of waste, especially human excrement, from water supplies. Domestic sewage contains solid and dissolved materials, such as fecal matter, urine, toilet paper, vomitus, food waste, soaps, and other cleaning agents. Separation methods include filtration, adsorption, and precipitation. Decontamination methods include biocides, chemical neutralization, and phagocytosis. Disposal involves collecting, handling, and destroying the final waste products in a manner that is safe for humans and the environment. These processes aim to provide improved water quality for drinking, cooking, and bathing.
