Install / Failure Note

Case-study engineering rule: closed-loop control with conditional discharge authorization is what prevents pH-overshoot when dosing caustic into a highly acidic stream — overshoot itself creates a second compliance failure on the other side of the scale, which is why manual batch treatment was rejected for this job.

Dosing caustic into a pH-3.3 stream on a timer instead of closed-loop feedback doesn't just risk under-treatment — it risks overshooting into a second violation. The two-stage holding-tank-plus-closed-loop-PLC architecture LibertyCES specified on this job exists to make that overshoot structurally impossible, not to trust an operator to catch it.
