|---|---|---|
| Case study inflow pH | pH 3.3 vs. municipal-required 5.5–6.5 discharge range | LibertyCES field case study: Automated Wastewater pH Treatment System |
| Federal pretreatment threshold | Discharge below pH 5.0 prohibited without special design | LibertyCES field case study: Automated Wastewater pH Treatment System |
| Civil penalty exposure cited | $25,000+ per day | LibertyCES field case study: Automated Wastewater pH Treatment System |
| Holding tank (stage 1) | Snyder Industries 4,500 gal polyethylene, double-wall | LibertyCES field case study: Automated Wastewater pH Treatment System |
| Mixer impeller material | 316 stainless steel 3-blade collapsible propellers (Grovhac) | Grovhac — Industrial Mixers |
| Grovhac stainless-shaft mixer HP range | 1/4–3 HP, direct or gear drive | Grovhac — Industrial Mixers |
A pH-3.3 stream isn't a corner case — it's roughly 5,000x more acidic than neutral, and federal pretreatment rules prohibit discharge below pH 5.0 without engineered design, which is why the case study pairs a 316-stainless impeller mixer with a closed-loop system rather than a coated mild-steel unit and manual dosing.
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.
