Industry Overview

Handling Chemical Processing Effluents

Chemical manufacturing generates wastewater with extreme pH from acidic and alkaline processes. pH must be neutralised to 6-9 before discharge to protect receiving waters and downstream treatment processes. Our automated pH neutralisation systems deliver precise control with minimal chemical consumption. Two-stage feed-forward and feedback dosing handles the full 0–14 pH range while minimising reagent use and avoiding overshoot. Every system logs pH and flow continuously, giving you the compliance record regulators expect.

Chemical Operations

Application Areas

Acid Manufacturing

pH neutralisation systems for sulphuric, hydrochloric, and nitric acid production wastewater, where strongly acidic rinse and spillage streams must be buffered and neutralised to consent before discharge.

Chemical Industry pH

Alkali Production

Acidic neutralisation for caustic soda and other alkaline chemical manufacturing effluents, dosing acid under feedback control to bring high-pH process water back within the 6–9 band.

Basic Chemicals

Metal Finishing

Precision pH control for plating baths, pickling lines, and surface treatment operations, combining neutralisation with heavy-metal precipitation to meet tight discharge limits.

Metal Finishing pH

Pharmaceutical

Automated neutralisation for API manufacturing and pharmaceutical process wastewater, handling variable batch streams with validated, fully logged pH control.

Pharmaceutical pH

Food Processing

pH adjustment for CIP cleaning cycles and acidic/alkaline food production effluents, smoothing the sharp swings between caustic and acid wash phases before biological treatment.

Food & Beverage pH

Laboratory Wastewater

Compact systems for research, university and QC facilities handling diverse, low-volume chemical streams — segregation, batch neutralisation and metals removal in a small footprint.
