Words and meanings to learn
waste water
used water that goes down the drain, including sewage, agricultural runoff and industrial waste
aeration
the process of pumping air (oxygen) into the water during secondary treatment to encourage aerobic microorganisms to grow and biologically break down the dissolved organic pollutants
sludge
the concentrated solid waste (containing grit and organic matter) that settles out of the wastewater during sedimentation, which is then collected and treated separately
sedimentation
the primary treatment stage where gravity is used to make heavier, insoluble solids (like grit and tiny food scraps) sink to the bottom of a tank, forming sludge
chlorination
final treatment stage where a sterilising agent (like chlorine or UV light) is added to the water to kill any remaining harmful microorganisms (pathogens) before the water is discharged
