This process helps in expelling soluble gases for example carbon dioxide and hydrogen sulfide (equally of that happen to be acidic, so this process helps make the water significantly less corrosive) and expels any gaseous natural and organic compounds an unwanted style to the water.
In modern day plants the screens are cleaned mechanically, and the material is immediately disposed of by burial around the plant grounds.
