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.

Why Precision pH Dosing Matters
In high-throughput industries like food processing and dairy production, even minor dosing delays can lead to fouled probes, solids carryover, or EPA discharge violations. Manual systems simply can’t keep up with flow rate volatility and batch variability.
Smart dosing systems combine inline pH monitoring with closed-loop PLC control, allowing real-time adjustments that reduce chemical usage and ensure compliance without guesswork.
- ✅ Reacts instantly to inlet fluctuations & low buffer loads
- ✅ Cuts chemical re-dosing with predictive correction logic
- ✅ Syncs with SCADA platforms for full process visibility
- ✅ Supports expansion via modular PLC integration
