Wastewater treatment is the process of removing impurities from wastewater, or sewage before it reaches aquifers or natural bodies of water such rivers, lakes, estuaries, and seas. Because pure water does not exist outside of chemical laboratories, any distinction between clean and contaminated water is made based on the type and concentration of contaminants present, as well as the water's intended usage. When water contains enough toxins to make it unfit for a specific purpose, such as drinking, swimming, or fishing, it is considered to be contaminated in general terms. Despite the fact that natural forces have an impact on water quality, the term "pollution" is usually associated with human activities. For more details please contact us! 9871151318
