APPLICATION OF VENTURI DIFFUSER DESIGN FOR HYPERSALINE WASTEWATER DISCHARGE INTO THE MARINE ENIVRONMENT

The discharge of hypersaline wastewater into the marine environment can be a challenging problem with respect to balancing minimisation environmental impacts and maximising cost efficiency across lifetime project. When density gradient between water receiving is large, this dominate nearfield mixing regime result in high-density, layer at seabed forming nearfield, extending farfield, zone. This remain virtually undiluted once it extends past zone turbulent region. enhanced sites variable bathymetry, including where dredged navigation channels may present, resulting that maintains high salinity over large spatial temporal scales. analyses diffuser design presented following sections are based on project site located coastal waters off Pilbara coastline northwest Australia.
