Sewage treatment is the process of removing most pollutants from wastewater or sewage and producing liquid effluent suitable for discharge to natural environment and sludge. In order to be effective, sewage must be transported to the treatment plant through appropriate pipelines and infrastructure, and the process itself must be supervised and controlled. Other wastewater usually requires different treatment methods, sometimes special treatment methods. The simplest treatment of sewage and most wastewater is to separate solid from liquid, usually through sedimentation. By gradually transforming dissolved substances into solids, usually biota, and precipitating them, an outflow stream with higher and higher purity is generated.
Sewage is liquid waste from toilets, bathrooms, showers, kitchens, etc., which is treated through sewers. In many areas, sewage also includes some liquid waste from industry and commerce. In many countries, waste from toilets is called dirty waste, waste from items such as washbasins, bathrooms and kitchens is called sewage, and industrial and commercial waste is called trade waste. In developed countries, it is becoming more and more common to divide household drainage into grey water and black water. Grey water is allowed to be used for watering plants or recycled for toilet flushing. Many sewage also includes some surface water from roofs or hard areas. Therefore, urban wastewater includes residential, commercial and industrial wastewater discharge, and may include rainwater runoff.
