Which Wastewater Requires Neutralisation in Industrial Wastewater Treatment?

Many industrial wastewater streams require neutralisation. These include spent acids and alkaline solutions, rinsing and washing water containing metal salts, as well as acidic and alkaline rinsing water from pickling processes used in metal surface treatment.

Alkaline degreasing wastewater from the pretreatment of metal surfaces and wash water from paint stripping processes may also require pH adjustment. Other applications include process and rinsing baths from electroplating processes, acidic phosphating baths, pH adjustment for heavy metal precipitation and pH correction before indirect discharge into the sewer system.

Advantages of Neutralisation with OKO-tech

OKO-tech systems perform neutralisation as part of physico-chemical treatment systems or integrate it as an individual treatment stage in flotation and emulsion breaking systems. Automated chemical dosing and modern sensor technology enable precise control of the pH value. This helps operators control chemical consumption, reduce maintenance requirements and support resource-conscious wastewater treatment.

Neutralisation also supports compliance with applicable discharge requirements and contributes to stable operation of the overall wastewater treatment process. OKO-tech combines process engineering expertise with automated control and practical treatment concepts to address both industrial requirements and environmental objectives.

Neutralisation can be carried out in physico-chemical treatment systems as well as integrated into flotation systems and emulsion breaking systems as an individual treatment stage in industrial wastewater treatment.
