Wastewater treatment

This multi-stage process is tailored to wastewater characteristics, with design targets set by the site permit, and receiving-water objectives. It combines physical steps—sedimentation, flotation, filtration, stripping, ion exchange, and adsorption—to remove dissolved and suspended substances; chemical steps—precipitation, oxidation or reduction, and stripping of generated gases—to convert or separate contaminants; and biological steps, where microbes consume organic, and in some cases inorganic, pollutants.

Industrial loads fluctuate with batch production and Cleaning-in-Place (CIP); systems manage this by segregating challenging streams and using equalisation to smooth flow and pH before downstream treatment. Closed-loop control of temperature, flow, pH, pressure, and volume is supported by diagnostics, interlocks, and alarm management. Live sensor data stabilise performance and energy use, and records are retained for regulatory purposes, with historian-backed trends and audit trails.
