    Wastewater Treatment and Water Purification | Boundless

    Tertiary treatment (sometimes called “effluent polishing”) is used to further clean water when it is being discharged into a sensitive ecosystem. Several methods can be used to further disinfect sewage beyond primary and secondary treatment. Sand filtration, where water is passed through a sand filter, can be used to remove particulate matter.

    Wastewater Treatment Water Use - USGS

    Wastewater treatment. The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.

    Water is then passed through a membrane filter to remove large pathogens such as cryptosporidum and giardia. To finalize the purification process, chemical disinfection (usually with chlorine or ozone ) or UV light is applied to the water to kill bacteria, viruses, and the hardy cysts produced by cryptosporidium and giardia.

    How Wastewater Treatment WorksThe Basics

    Most treatment plants were built to clean wastewater for discharge into streams or other receiving waters, or for reuse. Years ago, when sewage was dumped into waterways, a natural process of purification began. First, the sheer volume of clean water in the stream diluted wastes. Bacteria and other small organisms in the water consumed the
