ABSTRACT
Simply, wastewater is any water that has been contaminated by human use. The characteristics of wastewater vary depending on the source. Types of wastewater include domestic wastewater from households, sewage from communities, and industrial wastewater. Households may produce wastewater from flush toilets, dishwashers, washing machines, bathtubs, sinks, and showers. Households that use dry toilets produce less wastewater than those that use flush toilets. The difference between blackwater and greywater is mainly what makes it dirty. PFAS are found in a wide range of consumer products that people use daily such as pizza boxes, cookware, and stain repellents. The oxygen content of natural water sources has a direct impact on the quality of all-natural waterways. In many locations, municipal wastewater is carried together with stormwater, in a combined sewer system, to a wastewater treatment plant. It is important to point out that some water-demanding activities do not require wastewater treated to drinking water quality and standards.
