Project Overview

A milk powder production plant uses 1.5 litres of water for every litre of milk processed and removes about 0.75 litres of water. This water cannot be reused currently due to the presence of Biochemical Oxygen Demand (BOD) and milk volatiles. Furthermore, the available technology of Reverse Osmosis is highly energy and maintenance intensive and is not a viable solution.

Longwarry Food Park aim to use an innovative ozone based treatment from a company called Ozone Industries to treat the water content removed from milk in the production of powdered milk to remove BOD''s & milk volatiles to enable the water content to be re-used. This will result in potential of reduction of water use to 0.5 litres per litre of milk.
