Stabilizing Wastewater pH for a U.S. Cheese Processor

❌ The Challenge: Unstable pH & Chemical Overuse

  • No pH Sensor Feedback made corrections guesswork-based.
  • Overshooting due to batch flow swings and lag time.
  • Fouled Probes delayed dosing cycles.
  • Manual Dosing caused 18–25% acid & caustic overuse.
  • Title 22 Violations risked permit compliance (pH 6.0–9.0 limits).

Keywords: food plant wastewater treatment, fouled sensors, pH correction automation

✅ The Solution: Smart Dosing + Real-Time PLC

  • Closed-Loop Logic enabled real-time dosing via PLC.
  • Inline pH Sensors eliminated overshoot corrections.
  • Electric Pumps delivered low-flow precision control.
  • SCADA Integration ensured continuous data-driven feedback.
  • 24% Chemical Savings in both sulfuric acid and KOH usage.

Result: No compliance violations, scalable automation, 6–8 hours/week saved.

Live PLC Feedback

Real-Time pH Stabilization for Industrial Acid Injection

A U.S. food processor was injecting 50% sulfuric acid and 45% potassium hydroxide into 125,000-gallon tanks — blindly, without sensor logic. Overshooting and chemical waste were unavoidable.

With LibertyCES and the Graco QUANTM™ electric diaphragm system, chemical dosing is now controlled by inline sensor data and real-time PLC logic — adapting dynamically to flow conditions.

  • ✔️ Reduced overshoot & pH drift
  • ✔️ Dynamic response to batch flow
  • ✔️ Full SCADA integration
  • ✔️ 24% improvement in chemical efficiency

Automation turned trial-and-error into 24/7 chemical intelligence.
