BOC Kooragang Irrigation of Cooling Tower Effluent DA 8354
BOC owns and operates a gas facility on Kooragang Island for the production and supply of gas products. DA 8354 was designed for the safe and sustainable reuse of cooling tower effluent for on site irrigation.
Historically BOC disposed of the cooling tower effluent off-site using a waste contractor, ultimately to be processed by Hunter Water. The amount of cooling tower blowdown water produced and disposed was a significant cost to BOC’s operations. Therefore, BOC Kooragang performed investigations to determine that the cooling tower blowdown stream was suitable to be used to irrigate a selected area of land at the site as a full reuse scheme.
