The chemical dose controller increases the resiliency of AguaClara plants because operators are only required to adjust chemical dosing settings based on incoming turbidity, not based on flow rates. The linear chemical dose controller is currently comprised of three projectscomponents, the linear flow orifice meter, the flow controller, and the chemical doser. These components of the system act together to allow the plant to respond to changes in inflow by both linearizing the change in plant flow and automatically adjusting chemical dosing to the plant.

[Linear Chemical Dose Controller]
[Nonlinear Chemical Dose Controller]
* AThe linear dose controller hasuses beenmajor designedlosses to controladjust chemical doses whento flow in the dosingplant tubeas israw laminarwater basedflow on a linear relationship between headloss in the dosing tube and entrance tank level. This relationship does not hold rates change.
[Nonlinear Chemical Dose Controller]
* Major losses cannot be uses to adjust chemical flow rates when flow in the dosing tube is turbulent. Therefore, a chemical doser with a constant but nonlinear chemical dose response to nonlinear changes in plant flow is being designed.
[Gracias Entrance Tank Design]
* The design of the entrance tank for high flow rate plants such as Gracias. |
