Constituent Types

Hello,

I want to know that which option is better constituent type to carry out booster chlorination study at node in Water Distribution Network?

Thank You.

  • Hello Paras,

    Do you mean which constituent type that is available in the engineering libraries for WaterGEMS or WaterCAD? If so, I would review the properties of the constituent to see if it matches up with what you are trying to model. If it doesn't, you can add your own constituent to the Constituent manager and the engineering library.

    If this is related to constituent source types, see this link

    If this doesn't help, more details more be needed.

    Regards,

    Scott

  • I want to know that which constitutent source type is better to carry out booster chlorination study? Out of 4 constituent source types that you have provided in the link, which one is better to carry out booster chlorination study in WaterGEMS?

  • Hi Paras, there may not be a "correct" answer to this, as it depends on the situation. 

    There is a section in our Advanced Water Distribution Modeling and Management book that talks specifically about booster chlorination studies (starting on page 465), and points out the three booster options available to represent it (mass booster, flow paced booster and setpoint booster).

    I have updated the related article in alignment with the information in the book: Understanding Constituent Source Types and Constituent patterns

  • It all depends on how you want to control feed:

    If you want to continuously feed a known flow and concentration, use Concentration

    If you want to feed a constant mass flow rate , use Mass Booster.

    If you want to modify feed based on flow, use Flow Paced.

    If you wan to maintain a constant outflow concentration, use Set Point.

    I would say that most people who can afford it, use Set Point but it is the most complicated and expensive setup. It requires chlorine sensors and .a logical controller, while Concentration is the simplest/least expensive in terms of  equipment  but is limited in flexibility.
