Title A case study investigating the impacts of coagulants on taste and odour reduction in drinking water
Author(s) Callingham, T
Year 2017
Abstract The aim of this project is to determine the cost benefit of targeted taste and odour compound removal through the Goulburn Valley Water Euroa Water Treatment Plant (WTP). Volunteer Goulburn Valley Water Staff will be utilised to determine the effectiveness of taste and odour compound removal through optimisation of the existing treatment process and alternative coagulation chemicals.

It is hypothesised that elevated organics and/or the presence of algal metabolites within the raw water reservoirs are the key causes of poor taste and odour perceptions within the Euroa Community.

The key research questions regarding this project are:

· Does targeting optimisation of the water treatment plant for a specific taste and odour causing compound lead to a perceived improvement in taste and odour?

· Are any notable improvements in taste and odour proportional to the financial outlay for targeting the removal of specific taste and odour causing compounds?

· Are the associated benefits of taste and odour compound removal proportional to the financial outlay?

The specific materials that are being focused on are natural organic matter (NOM) and geosmin. These have been identified as potentially being the key contributors to taste and odour at Euroa. The impact of these on current production costs and some potential removal pathways of these materials will be explored.
