2. Level of turbidity interferes with the disinfection process
FILTRATION
Settled water has a turbidity in the range from 1 to 10 NTU (typically 2 NTU)
Level of turbidity interferes with the disinfection process
Turbidity must be reduced further after the sedimentation process.
It is important that the treated water turbidity level to be below 0.3 NTU (1 NTU is regulatory)
Filtration is used to remove turbidity to required levels Dr
