Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Case-study holding tank | 4,500-gallon, polyethylene, double-wall holding tank (Snyder Industries) | LibertyCES field case study: Automated Wastewater pH Treatment System |
| Influent pH before treatment | pH 3.3, roughly 5,000x more acidic than neutral, vs. a municipal-required discharge range of 5.5-6.5 | LibertyCES field case study: Automated Wastewater pH Treatment System |
| Regulatory penalty exposure | $25,000+ per day in civil penalties for non-compliant discharge below the federal pretreatment pH 5.0 threshold | LibertyCES field case study: Automated Wastewater pH Treatment System |
| System flow rate | 20,000-40,000 GPD (gallons per day) | LibertyCES field case study: Automated Wastewater pH Treatment System |
Closed-loop control with conditional discharge authorization prevents pH-overshoot when dosing caustic into a highly acidic stream — critical because overshoot itself creates a new compliance failure rather than fixing the original one.
Dosing caustic into a pH-3.3 acid stream by manual batch judgment risks overshooting past the 5.5-6.5 compliance window into a second, equally non-compliant failure. This case study replaced operator judgment with closed-loop PLC control — non-contact radar level plus inline pH — precisely because a $25,000-per-day penalty exposure doesn't tolerate an overshoot error.
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.
