pH Correction in Wastewater Treatment

The pH balance is an essential parameter in controlling and regulating wastewater treatment. Corrections to pH can help optimise conditions for other treatment processes, such as coagulation and ensure effluent water is safe for release into the environment. Proper pH regulation protects human and environmental health.

We are proud to offer an effective range of high-quality coagulants suitable for use in wastewater treatment. Download our pH Correction Product List here or scroll down to find out more.
