Real Specifications
| ProMinent gamma/X capacity | 1 ml/h – 45 l/h at 25–2 bar back pressure | prominent-metering-pumps.md |
| SPECTRA transfer pump | 2.4 – 12,000 l/h at 12–3 bar; meters concentrated/dilute liquid polyelectrolytes for sludge dewatering | prominent-metering-pumps.md |
| Case study pH correction | 20,000-40,000 GPD plant brought from inflow pH 3.3 to a consistent 5.5-6.5 compliant range | automated-wastewater-ph-treatment.md |
| Case study penalty exposure | Non-compliant discharge below pH 5.0 carried civil penalty exposure of $25,000+ per day | automated-wastewater-ph-treatment.md |
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.
