Bring back chlorine-free
AN ARTICLE in last week’s Gazette refers to “whether Mossman can become the first town in Australia to trial a chlorine-fee water supply”.
It appears the question is four years behind the times as the whole shire was receiving chemical free water in 2007.
In 2004, Council surveyed ratepayers about water supply - giving them various options for purifying the water which included the use of chlorine, chloabonation, ozone, conventional treatment, and microfiltration.
While microfiltration was the most expensive of the lot, it was also the most popular.
More than half of respondents wanted clean and chemical-free water, and were prepared to pay more to get it.
In response to the survey, the former Douglas Shire Council commissioned Koch Membrane Systems with disinfection provided by Hanovia Ultraviolet Disinfection System to complete the installation of ultrafiltration membranes and ultraviolet disinfection system in its three water treatment plants.
These methods worked by filtering water from catchments through tiny permeable membranes and trapping contaminants inside.
The contaminants are than removed and used for landfill.
The result was the purest water in the world, which is exactly what the residents wanted and got in 2007.
