Chemical Dose Controller

Overview

The AguaClara Chemical Dose Controller is a critical piece of the AguaClara technology . It which couples the plant flow rate with the flow rate of the coagulant or disinfectant stock solution. The result is a semi-automated system in which the plant operator only needs to set a dose for the chemical and it will be administered automatically as the plant flow rate varies. The device has evolved steadily with major advances every year. The ability to accurately and predictably control the alum and chlorine dosages without using electricity sets the AguaClara technology apart from previous other water treatment technologies. Our Dose Controller technology that couples plant flow rate and chemical dose is novel.

In the latest design, the The Non-Linear CDC makes it possible for an operator to set the chemical dose without referring to any tables. This could be a significant advantage. The disadvantage is that this design is more complex and thus we will need to work this carefully to ensure that the CDC technology is sustainable.
