Sewage treatment water pollution Most municipalities in America treat their sewage (wastewater) using two basic processes: primary treatment (a physical process) and secondary treatment (a biological process). This kind of pollution leads to health-related and environmental issues. Using a treatment process that simulates the way nature cleans water, the Facility treats an average of 110 million gallons of wastewater per day (mgd), with a capacity of up to 167 mgd. Wastewater treatment - Pollutants, Contamination, Purification: Water pollutants may originate from point sources or from dispersed sources. At the plants, physical and biological processes closely duplicate how wetlands, rivers, streams and lakes naturally purify water. The process of removing harmful substances from wastewater is known as sewage treatment. Untreated sewage is the leading polluter of water sources in India, causing a host of diseases including diarrhea (which kills 350,000 Indian children annually 2), agricultural contamination, and environmental degradation. Industrial wastewater, rich in organic substances, heavy metals, and toxic chemicals from sectors like manufacturing, mining, and petrochemicals, poses significant health and environmental risks. Treatment plants are essential infrastructures in combating water pollution. Sewage Treatment Plant. tbhzn gxfpp mjkl bupq jpcbwdc yttfp kktrnak dzmu bgsb rxb
