|A and C are correct because detention period for water using coagulants is 2-6 hours.|
|Hitler said: (Apr 21, 2017)|
|All the given options are correct.|
|Vivek said: (Nov 30, 2017)|
|According to me, it is The horizontally flow velocity in sedimentation tanks, is generally limited to 0.3 m/s not m/ min.|
|Ajay said: (Nov 20, 2018)|
|Dt for plain sedimentation is 3-4hr.|
|Vivekanand Pandey said: (Dec 4, 2019)|
|For plane sedimentation td is 24 hrs.|
|Spoo said: (Feb 8, 2020)|
|0.3m/min is accurate.|
|Kuntal Meena said: (Feb 18, 2020)|
|Plain sedimentation detention time 3-4 hrs and with coagulation 2-2.5 hrs and hrz. Velocity. 3 m/minute.|
|Kiran said: (Mar 2, 2020)|
|Detention period: for plain sedimentation: 3 to 4 h, and for coagulated sedimentation: 2 to 2.5 h. Velocity of flow: Not greater than 30 cm/min (horizontal flow). Tank dimensions: L:B = 3 to 5:1.|
|Mira said: (Nov 29, 2020)|
|Detention period for plain sedimentation is 3 to 4 hr and for coagulated sedimentation is 2 to 2.5 hr.
The horizontal flow velocity in the sedimentation tank is limited to 0.3m/min.
