Wastewater Treatment

January 2024 – Municipal Wastewater, commonly known as sewage, is generated from household liquid waste such as toilets, showers, kitchens, and sinks. Wastewater contains toxic contaminants that must be treated to protect human health and the environment. Wastewater quality parameters are classified based on their chemical, physical, and biological properties. The wastewater treatment process comprises three main stages: primary, secondary, and tertiary treatment. In the primary stage, solids are allowed to settle and removed from wastewater. The secondary stage uses biological processes to remove organics. The tertiary stage uses filtration to remove nutrients. In 2013, the United Nations Environment Program (UNEP) launched the Global Wastewater Initiative (GWWI) to tackle wastewater pollution around the world.

In this slideshow, you will learn about the definition, sources, quality parameters, stages, process, UN policy, and global statistics of wastewater treatment. Discover how wastewater is generated, treated, and the market value of the global wastewater treatment industry.
