What is pH Correction?


The term “pH” refers to the measurement of hydrogen ion activity in the solution. pH correction is the process of amending a pH level to fit certain parameters. Very extreme levels, abundance of particulate matters, accumulation of toxic chemicals and increasing alkalinity levels are common pH based issues in wastewater. 

Why is pH Correction Important?


A pH that is too acidic or has too much alkaline is deemed toxic for the environment. To counteract this a Coagulant can be added to reduce acid levels, lowering the pH. Similarly, for wastewater with too high an alkali level, Caustic can be added to raise the pH level.

According to the EPA, pH levels for wastewater must be within 6.6 and 7.3 on the pH scale. Anything outside of this would be deemed damaging and can be actioned upon. 

How We Can Help


Our Dissolved Air Flotation unit range offers a pH correction facility whereby you can adjust your wastewater pH on the fly. This highly adaptable system can help you to avoid fines and maintain a sustainable level of pH.

Additionally Watermark Projects can offer Chemical Treatment/ Mixing vessels as well as Chemical Storage/ Dosing Equipment to further control your pH levels.
