Since we live, work and play so close to water, harmful bacteria have to be removed to make water safe. Chlorine compounds and inorganic chloramines can be toxic to aquatic invertebrates, algae and fish. Steps in the wastewater treatment process. For instance, some wastewater systems are in low-lying areas that are especially prone to the impacts of flooding, while others may be in drought-prone regions or areas with increasingly frequent wildfires. << OR-TEC, Incorporated based in Cleveland, OHIO (USA) Founded in 1980, OR-TEC specializes in the manufacture and sales of wastewater treatment equipment for the municipal and industrial marketplace. A lock () or https:// means youve safely connected to the .gov website. So wastewater-treatment plants are located on low ground, often near a river into which treated water can be released. 0 But reclaimed wastewater has many uses, with more promise of usage in the future. Ultraviolet (UV) disinfection is an alternative to chlorination that does not add chemicals to the water. Environment Canadaprovides some examples of pollutants that can be found in wastewater and the potentially harmful effects these substances can have on ecosystems and human health: 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. Currently, 62.5 billion gallons of wastewater per day is being treated by centralized WWTPs. U.S. EPA (2000) Wastewater Technology Factsheet: Chemical Precipitation. More than 100 expansion or modernisation projects are launched each month in the US municipal wastewater treatment sector, which includes approximately 16,000 plants, according to the McIlvaine Company online database (www.mcilvainecompany.com) Capital needs for these plants will average close to US$ 10b per year over the next decade. Adapted from Arkansas Watershed Advisory Group. Over the last two decades, more than 200 of the nations largest combined sewer systems (those serving > 50,000 people) have been identified and had actions taken to reduce unlawful discharges that degrade water quality.
