Food-grade acid and alkali dosing for CIP systems, dairy pH adjustment, brewing water treatment, and vegetable wash water neutralisation.
From dairy CIP to brewery mash pH and vegetable brine neutralisation, food-grade acid and alkali dosing ensures product quality, safety, and effluent compliance.
Clean-in-place cycles use caustic soda (pH 12–13) for cleaning and phosphoric or nitric acid (pH 2–3) for rinsing. pH correction neutralises effluent to 6–9 before discharge.
Mash pH (5.2–5.6) affects enzyme activity and beer flavour. Lactic or phosphoric acid adjusts mash pH; caustic soda neutralises acidic wastewater from bottle washing and CIP.
Peeling and blanching often use lye (NaOH) solutions at high pH. Acidic rinse water and brine neutralisation requires controlled acid dosing with corrosion-resistant materials.
Dough conditioners and process water pH affect gluten development. Weak acids adjust water pH; effluent from washdown requires pH correction to meet sewer discharge limits.

Discover MorepH correction is a critical stage in wastewater and process water treatment. Incorrect pH can damage downstream biological systems, corrode pipework, violate discharge consent limits, and compromise product quality. Our dosing systems utilise flow-proportional control with automated feedback loops to maintain target pH within ±0.2 units, regardless of influent variability.
Rapid mixing and reaction kinetics ensure complete neutralisation before downstream processes.
Flow-paced and feedback-controlled dosing eliminates chemical wastage and overshoot.
Systems account for influent buffer capacity to calculate precise reagent requirements.
Automated temperature compensation ensures accurate pH measurement across seasonal variations.
