A Wastewater Treatment Plant is a complex process that removes pollutants from wastewater and releases the clean water back into the environment. It is important to understand how it works to choose the right one for your facility. A typical WWTP has several stages, each one with a different purpose. The wastewater is treated to ensure that it is safe to drink, and the treated water is released into the receiving waters again.

A WWTP processes sewage, or wastewater, to remove pollutants and solids from it. It also breaks down organic materials to increase oxygen content in the treated water. The plant uses three operations - primary treatment, secondary treatment, and sludge treatment - to clean wastewater. The wastewater is collected from a network of sewers that connects to homes, schools, industry and businesses. The solids are transported to the WWTP's collection tanks during the treatment process.

The effluent of a WWTP contains a wide range of pollutants. During sludge discharge, fibers from domestic laundry were the most abundant. In addition, there were no detrimental effects on organic load. However, the influent of a WWTP increases the rate of solids accumulation in anaerobic ponds, increasing the rate of solids accumulation from 143 mm to 141 mm per year. This reduced the operating time before desludging and dredging.
