Melbourne Plant Water Reduction
At the beginning of 2007, the Plant upgraded a number of Towns water cooled systems to recirculating closed-loop systems.
• This had a significant on water consumption To further reduce water consumption, a Lean Six Sigma Project (led
by Michael Brown) was commenced. A number of water reduction activities and projects were carried out
including:• Temperature controlled Variable speed drives on cooling tower
fans• Awareness education amoungst all Employees• New floor cleaning equipment• On-line water metering• Installation of low-water consumption cooling towers on air
compressors

Melbourne Plant Water Reduction – New Cooling Towers
The new compressor cooling towers were a significant departure from “normal” cooling towers:
• Closed loop• Used an air-water heat exchanger• When temperatures low, air was the only cooling used• When temperatures were high, water-cooled evaporative pads
were used to pre-cool the air prior to the air-water heat exchanger
• Control of water and fan speed through PLC logic.

Melbourne Plant Water Reduction – New Cooling Towers
Significant water savings have been achieved by using these towers• Water reduction from approx. 70m3 / day to 20m3 / day• Reduction of Legionella risk• Reduction of fan power from approx. 166kW to 110kW• Elimination of water treatment chemicals:

Melbourne Plant Water Reduction
O-I uses an internal Benchmark for water consumption Based on the water used per glass bottle-making machine per day Best Practice is 30m3 water / machine / day Melbourne Plant is now one of the lowest users of water in the O-I Group
