Conventional Water Treatment Plant

Activated carbon filter is one of the most widely used media for absorption of impurities. In water treatment the activated carbon is employed for:

• Dechlorination
• Removal of Organics
• Removal of Odour

The specific velocity to be employed depends upon the use as well as the treated water quality desired. It also depends upon the nature of Activated Carbon in terms of its pore size, degree of activation, particle size and bed depth. However, typically we use following design parameters:

• Max. service velocity for dechlorination – 15 m/hr
• Max. service velocity for organic removal – 10 m/hr
• Max. service velocity for odour removal – 10 m/hr
• Back wash velocity – 5-6 m/hr
