# 8.3.7 Adjustment of pH Adjustment of pH is important in drinking water treatment processes such as coagulation (particularly for the removal of natural organic matter), corrosion control and softening. Control of pH is also important for effective disinfection and to minimise the formation of disinfection by-products. The efficiency of certain disinfectants is strongly dependent on pH. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://guidelines.nhmrc.gov.au/australian-drinking-water-guidelines/part-2/chapter-8/8.3-overview-of-chemical-treatment-processes/8.3.7-adjustment-of-ph.md?ask= ``` The question should be specific, self-contained, and written in natural language.
