Currently, potable water is being used for coal dust suppression in a power station in Gladstone, Australia. The feasibility of reclaiming a close source of 2nd class effluent supplied by the Gladstone City Council, to replace the potable water supply for coal dust suppression is investigated in this paper. Due to the nature of the water, specific attention is given to understand and determine the physical properties of the 2nd class effluent in regards to environmental and work place health and safety (WH&S) issues. UV treatment system has been identified as a suitable treatment technology in order to raise the rating of 2nd class effluent to Class A which is suitable for coal dust suppression. Safety and environmental concerns of UV treatment system is elaborated. Then, the fluid flow system design and calculation is presented to meet the requirements for safe operations of reclaimed water re-use for coal dust suppression.
