Water Treatment Analyser Article from Operator Newsletter (96kb PDF)
The Water Treatment Alliance and the Water Services Association, with support from the Victorian Department of Health, have developed some Excel based software tools to allow Water Utilities and Water Treatment Plant (WTP) operators to assess the performance of their plants at the two key control points for pathogen control, namely media filtration and chlorine-based disinfection.
Instructions for use:
- Select the Analyser from the links below
- Select “Save” and navigate to your preferred folder location, and select Save.
Do not change the workbook name.
- Close MS Excel.
- The tools must be opened from MS Excel and not from file manager.
- Start Excel. Go to File/Open, navigate to the saved file location and select the file. Click on open.
- Follow the on-screen instructions to use the tools.
The WTAnalyser allows you to download and extract data from SCADA trends for detailed analysis. Since the trending system samples at short time intervals, very large amounts of data make up the trends. The first step is to extract a subset of the data for further analysis.
Water Treatment Analyser Disinfection - Spreadsheet (v3.0 Excel Spreadsheet)
This tool has been developed to assist you in analysing the performance of filters at your plant. It extracts data from other MS Excel or csv files. Once data is selected it is automatically processed into a graphical and statistical format that will tell you how your filters are performing.
