Issues / requests
Inject a flocculant (PAC) for slow sand filtration and inject chlorine into the filtered water. Pump configuration was complicated because the PAC injection volume was not proportional to the turbidity.
Adopted "linearize" control, which calculates the turbidity value _and the amount of water flowing through it. Appropriate PAC injection can be performed, reducing unnecessary chemical injection _and reducing costs. In ProMix, in addition to simple "flow rate proportional control", "linearize control" that performs output calculation from multiple items of flow rate change _and turbidity change is also possible.
