|
|
For schemes with ground water as source, only disinfection by chlorination is being practiced. |
|
|
For schemes with ground water as source which contains excess iron, aeration and excess lime treatment followed sedimentation, filtration and disinfection are being practiced. |
|
|
For small water schemes up to 2.5 mld capacity with surface water source where the turbidity is low, plain sedimentation followed by slow sand filtration and disinfection are the process adopted. |
|
|
For high turbid surface water schemes with more than 2.5 mld capacity, the process being adopted are aeration, coagulation and flocculation, sedimentation, filtration and disinfection. |
The Urban Water Supply Schemes are provided with conventional treatment units, where as most of the Rural Water Supply Schemes have infiltration gallery at intake followed by disinfection (chlorination) process before the water is distributed through the distribution network.
