Cleaning Up:
Automated Wastewater
pH Treatment System
Transforming non-compliant discharge at 3.3 pH into city-approved effluent in the 5.5–6.5 pH compliant range — fully automated, zero operator guesswork.
This system is a fully automated two-stage industrial wastewater pH neutralization solution designed to treat 20,000–40,000 gallons per day of acidic discharge (3.3 pH) and deliver consistent municipal-compliant effluent within the 5.5–6.5 pH range using closed-loop chemical dosing, continuous mechanical mixing, and PLC-controlled conditional discharge authorization. Key components include ProMinent Fluid Controls (metering pumps, radar level sensors, pH sensors, Dialog X PLC controller), Grovhac (industrial mixers), Georg Fischer (electromagnetic flow meters), and Snyder Industries (polyethylene chemical storage tanks).
Spec This System Yourself —
Before You Talk to Anyone.
The Automated Wastewater pH System Specification Checklist is built from this exact installation. It walks through every engineering decision in a system like this one — tank sizing, sensor selection, caustic overshoot prevention, secondary containment requirements, and IIoT compliance reporting. Use it to evaluate your current setup, challenge a vendor proposal, or walk into a spec conversation knowing exactly what you need.

When Compliance Is
the Business Risk
A client operating a small manufacturing plant faced severe compliance issues — discharging wastewater at a dangerously acidic pH of 3.3. Municipal regulations strictly mandated that effluent pH be raised above 5.5 before entering the public sewer system.
The system needed to reliably treat an estimated volume of 20,000 to 40,000 gallons per day. At that peak rate, the plant handles approximately 14.6 million gallons of corrosive wastewater per year.
To eliminate operator judgment errors, prevent compliance risk, and protect municipal infrastructure, LibertyCES engineered a fully automated two-stage neutralization system.
Under federal pretreatment rules, discharging wastewater below a pH of 5.0 into a public sewer is prohibited unless the system is specifically designed to handle it. Financial exposure ranges from $1,000–$5,000+ per day in municipal administrative penalties and up to $25,000/day in civil penalties.
Physical Infrastructure:
Inflow & Holding — The FOG Tank
Robust primary containment and continuous level monitoring form the foundation of environmental risk mitigation. Every gallon of acidic inflow is captured, measured, and managed before treatment begins.
The wastewater is initially diverted into a 4,500-gallon Snyder holding tank, designated as the FOG tank. This vessel serves as Stage 1 — the intake and buffer point for all corrosive inflow before any active treatment occurs.
To mitigate the risk of vessel failure and protect the surrounding environment, the holding tank is placed within a double containment setup. This secondary containment system ensures that even in the event of a tank rupture or seal failure, no acidic material escapes to the environment or drainage system.
A Prominent radar unit is installed on the tank to provide continuous, non-contact level monitoring — tracking the liquid level in real time and dictating precisely when the system transitions from containment to active treatment, triggering the transfer pump automatically at a preset level of approximately 115 inches.
