Describe the process of off-line flow equalization.
Answers
Equalization:
•It is the method of retaining waste in a basin so that the effluent discharge is fairly uniform in its characteristics.
•The main objective is to minimize or control fluctuations in waste water characteristics in order to provide better condition for subsequent treatment.
•The purpose of equalization is to provide adequate damping of organic fluctuations inorder to prevent shock loading of biological treatment.
•It also provide adequate pH control or to minimize the chemical requirements for neutralization.
Offline equalization :
In the offline arrangement only the flow above some predetermined flow limit is diverted into the equalization tank although the pumping requirement are minimized in this arrangement. The amount of constituent concentration clamming is considerably removed. Offline equalization is sometimes used to capture first flush from combined collection.
It's type is also neutralization but i have not explained here as u have not asked :p
Hope it helped u
