This successfully eliminated the filters’ turbidity breakthrough, increased plant production rate by 31%, increased all the filters run time by 60-300% and achieved significant chemical savings in the range of 20-51% (The developed process model can be applied to any water filtration plant for process optimisation.

The statistical process model developed by Sydney Water anticipates filter turbidity breakthroughs due to weak flocs and identifies the optimum chemicals dose to improve floc strength during treatment.The developed process model was applied at Nepean WFP during October to December 2016 in high colour event for raw water true colour of 25 HU @400 nm. Dr Luke Mosley of the Environmental Protection Agency discusses water quality risks in the lower River Murray and lakes associated with the extreme drought.There are many signs of improvement, but we are just at the start of the journey to return the river to health and a sustained effort is needed to ensure we have a healthy, working river for the future.The Department for Environment and Water acknowledges Aboriginal The Age.

The economic impact of water reductions during the Millennium Drought in the Murray-Darling Basin. Sydney’s eleven dams can store 2,581 billion litres of raw water (the largest, Warragamba Dam can store 2,027 billion litres water (Figure 1). 2 The physical dimensions of the “Millennium Drought” The recent drought (sometimes referred to as the Millennium Drought) was the worst in the last 110 years (Timbal, 2009), which is the period of high quality records National Water Initiative Pricing Principles Regulation Impact Statement.

Increased DOC with increased true colour and elevated fractions of DOC in raw water have been identified as the root cause for weak flocs formation during treatment, leading to decreased filtration rates, plant production capacity and filter performance.True colour is a reflection of various compounds in the raw water. Land Use Policy 26(4): 1195–1204.Hoang, M., et al. The state of the resource. The drought ended with the return of a La Niña event in early 2010 that brought high rainfall and large‐scale flooding.The millennium drought had a significant effect on agriculture, particularly on water-intensive crops such as cotton.
