Project Background

Queensland, Australia – Oakey Power Station is located 150km to the west of Brisbane. Oakey is owned and operated by Oakey Power Holdings, is located on the eastern Darling Downs and is capable of using liquid fuel or gas.
The two gas turbines provide fast starting, and can be operated on either natural gas or liquid fuel.

 

The Client’s Needs

The water treatment plant was installed at Oakey Power Station and treats bore water for power generation. Bore water fed into the Raw Water Storage Tank also serves as fire fighting water.

 

Project & Technology Solutions

Multi-media Filtration - dimensions for 1850mm x 2200mm. Removes any suspended solids from the feed.
 
UV Sterilisation - significant TOC reduction is achieved due to the breaking of chemical bonds in organic compounds by the UV radiation emitted. This radiation also damages the DNA of nay micro organisms, preventing their reproduction and replication.
 
Reverse Osmosis - the RO membrane elements reject over 98% of dissolved solids.

Degassing - permeate of 54 m3/hr flow rate enters the degasser tower where CO2 is removed and water pH is corrected.

Ion Exchange Demineralisation - removes cation and anion salts and consists of: cation Unit (replaces cations in the water with H+ ions), anion unit (replaces anions in the water with OH-ions) and hipol polisher unit.
