![]() ![]() In this process, strong objects are trapped by sieving procedures and suspended solids are eliminated by sedimentation. The primary level of treatment includes the removal of unwanted, suspended, or dissolved solids from sewage. The treatment process takes place in a wastewater treatment plant. Wastewater treatment easily removes impurities from wastewater and is converted into an effluent that can be returned back to the water cycle or reused. So, Proper treatments need to be carried out before it is exposed to another body of water.īy treating wastewater, we can protect the environment and the planet as a whole.

What Kinds of Wastewater Treatment Systems Exist? This process helps prevent pollution and protects human health and aquatic life. Wastewater treatment is the process of removing harmful substances from wastewater before it is released into rivers, lakes, streams, and oceans. The presence of pathogens, organic and inorganic matter, suspended particulates matter, dissolved gases, paint emulsions, pesticides, bio-solids, and many more undesirable substances necessitate the use of wastewater treatment. Depending on the source, the composition of wastewater ranges from mildly polluted storm water run-off to toxic wastewater from chemicals, pharmaceutical, and metal industries. ![]() It contains many different types of chemicals that can cause harm to humans and environment if not treated before release. Wastewater can begin from a variety of sources such as residential, industrial, business, or agricultural activities, etc. ![]()
