Surface overflow rate for Plain sedimentation tank = 12000 to 18000 lit/day/m2.
SOR for plain sedimentation with coagulation=24000 to 30000 lit/day/m2. Cover it to hours, we get 24000/24 lit/hr/m2= 1000.
Similarly, for 30000/24 = 1250 lit/hr/m2.
SOR for plain sedimentation with coagulation=24000 to 30000 lit/day/m2. Cover it to hours, we get 24000/24 lit/hr/m2= 1000.
Similarly, for 30000/24 = 1250 lit/hr/m2.

Type 1:- 12-18m^3 per day per m^2.
Type 2:- 24-30m^3 per day per m^2.
Type 2:- 24-30m^3 per day per m^2.

12000-18000 lt/m2/day.
So, the answer should be - 500-750 lt/m2/Hr.
So, the answer should be - 500-750 lt/m2/Hr.
