Disinfection of water (potable or recycled) with a chemical disinfectant (chlorine or chloramine) requires time for the chemical to react with and kill the target microbial pathogens. Ideally, the time for the reaction is provided in a purpose-built reactor or contact tank as this is specifically designed for this purpose and provides a controllable process. The reality however is quite different. Most water supplies rely on disinfection to occur in clear water tanks and reservoirs of various sizes, with various arrangements of inlet and outlet structures and varying levels of short-circuiting. The effective contact time is often less than is assumed.

Many water utilities use a target free or total chlorine residual in their treatment systems to achieve a level of disinfection that they understand to be adequate. This approach to disinfection can be improved in most cases.

Water Treatment Analyser Tools

 Water Treatment Analyser Article from Operator Newsletter (96kb)

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.

Ixom provides competency-based training courses relating to chemical use within the water industry. These courses are designed to be focused on the safe handling and storage of hazardous chemicals to ensure operator safety and for the organisation to meet its legislated work health and safety training requirements.

Ixom’s training programs are based on our 80+ years’ experience of manufacturing and supplying hazardous chemicals into industry in Australia and New Zealand.

The benefit and aim of our training programs is to:
• Reduce customer risk profiles by ensuring your personnel work from a “Knowledge Base” rather than “No Knowledge base.”
• Provide training that is competency based where required.
• Know how chemicals behave under certain conditions and how to use them safely.
• Meet your work environment applications.
• Meet your regulatory obligations and needs.

The courses we deliver are designed in primarily in two Levels (Awareness, Operator) to meet the specific needs of the operators and their organisations. Site specific procedures, such as connection and disconnection for chlorine gas containers and emergency response procedures, are reviewed prior to the training delivery to ensure that the training programs are customer and site specific as much as possible.

Chlorine Gas Awareness (Level 1) and Safe Use and Emergency Response (Level 2)
Chlorine Gas Installation Maintenance (Level 2)
Sodium Hypochlorite Awareness (Level 1) and Safe Use and Emergency Response (Level 2)
Corrosives Awareness (Level 1) and Safe Use and Emergency Response (Level 2)
Corrosives Installation Maintenance (Level 2)
Fluoride Awareness (Level 1) and Safe Use and Emergency Response (Level 2)
WH&S Risk Management (Chemicals)
Chlorine Emergency Response Plans (Desktop and Field Exercise)

Ixom’s Chlorine Safe Use and Emergency Response course can also be RPL’d into NWPTRT007 Monitor and operate liquefied chlorine gas disinfection processes via a third-party RTO.

Ixom also run installation auditing programs covering chlorine gas and corrosives that are designed to assess against current relevant standards (AS2927, AS3780). These audits produce a list of recommendations to meet the standards and, where appropriate, ensure that risks are managed ‘so far as reasonably practicable’ (sfarp). The requirement to have risks managed from a sfarp perspective underpins all current state based WHS and OHS Regulations.

If you wish to find out more detail regarding the programs please contact our training administrator at

WTPO Helper

As a water treatment operator Michael Fawcett from South Gippsland Water identified the need for an app to assist with dosing room calculations, either when changing the dose rate mg/L or working out the dose rate from the mL/min taken from the drop test. The idea was driven by his desire to do away with pens and paper and have the timer and the calculator right in his pocket.

The WTPO Helper app includes 15 calculations and 4 useful data loggers used in the day to day data collection operations of Water and to a lesser degree wastewater plant. Our jobs require a large amount of data to be recorded and the WTPO Helper has some useful tools to make this easier for operators.

The Calculations
• Chlorine Gas Feed Rate
• Solution Chemical Feed Rate
• Chloramination Ratio
• Dry Chemical Feed
• Dosing Solution Strengths
• Jar Test Solution Make Up
• Detention/CT Times
• Total Suspended Solids
• Total Dissolved Solids
• Maintenance Mains Volume Calculations

The Data Loggers
• Drop Test Timer and Logger
• Meter Logger
• Flushing Timer and Logger
• Dam Surveillance Timer and Data Logger
