CASE STUDY Manangatang Water Treatment Plant (Grampians Wimmera Mallee Water authority) Country: Australia Client: • Grampians Wimmera Mallee Water authority • Location, Manangatang , Victoria. Approx. 100km west of Swan Hill and 4.5hrs drive from Melbourne. Application: • Polishing Drinking water. The Challange: • Murray River To Potable water. • Inlet water quality is 10-40 NTU most of the year, and in some case 50-60 NTU. • Colour is around 400 Hu. • Supply filtered water at the point of disinfection of less than 1NTU, (Note, potential future new guidelines will be between 0.2 to 0.5NTU for potable water), at a Flow rate of 18 m³/hr (5L/sec) up to 21.6 m³/hr (6L/sec) and minimal initial cost to GWM. Water source: • Murray River Flow rate • 18-21 m³/hr Main Target • Reduction of Turbidity (Less than 1 NTU), Colour &TSS to Drinking water Guidelines. Reduction of Cryptosporidium.
