Real Specifications
| Target compliant discharge range | pH 5.5–6.5, up from inflow pH 3.3 | automated-wastewater-ph-treatment.md |
| Metering pumps | ProMinent Fluid Controls metering pumps dose caustic into the neutralization tank | automated-wastewater-ph-treatment.md |
| PLC controller | ProMinent Dialog X, closed-loop control | automated-wastewater-ph-treatment.md |
| System throughput | 20,000–40,000 GPD | automated-wastewater-ph-treatment.md |
The case study's own engineering rule: closed-loop control with conditional discharge authorization prevents pH-overshoot when dosing caustic into a highly acidic stream — overshoot itself creates a new compliance failure, not just a missed target.
Manually dosing caustic into a pH-3.3 stream risks overshooting straight past the 5.5–6.5 compliant window into a new violation on the high side, which is exactly why this build uses a ProMinent Dialog X closed loop instead of operator judgment to dose against a moving pH target.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
