Intelligent Water Treatment Process Selection
Annual Conference
❄
Selecting the most appropriate treatment process or technology for a new or upgraded water treatment plant (WTP) can be challenging. For City and District Councils with limited budgets, selecting the wrong process or technology can have significant cost and operational implications.
These risks can be mitigated by taking a careful and intelligent approach to WTP process selection through the development of a multi-season database of key water quality parameters. Some common drinking water treatment processes, how they address treatment challenges as indicated by the water quality parameters, their limitations, and how they meet the requirements of the Drinking Water Standards for New Zealand (DWSNZ) are summarized. The importance of bench- and pilot-scale testing, and the impact the data can have on the WTP design is highlighted through past projects to illustrate the concepts presented.
