➤ How does aeration increase or decrease turbidity in a treatment plant?
Aeration introduces air and mixing, changing dissolved oxygen and pH. It can oxidize dissolved iron or manganese into fine particles and temporarily raise turbidity (for example, 50 NTU to ~80 NTU). Aeration can also aid floc formation, which helps subsequent coagulation, sedimentation, and filtration reduce turbidity to below 1 NTU.
