Every dosing pump, bleed valve, or injector in a water treatment system runs on one of four control strategies: on/off, proportional, PID, or fuzzy logic. Most operators never choose one deliberately — they inherit whatever came bundled with the controller and only notice a problem once conductivity starts swinging wildly, a discharge line drifts out […]
