    The future long-term water supply of the Broken Hill Region was secured with the construction of a 270km pipeline from Wentworth to Broken Hill.  The pipeline is designed to deliver upto 37 megalitres of raw water a day to the region.  

    A key component in this project is a 720 Megalitre bulk water storage facility just outside of Broken Hill.  Water is delivered into two bulk water dams where the water is detained prior to being treated for consumption in the Water Treatment Plant in Broken Hill.

    The Primary concern of the project team was how to ensure that the water being delivered to these bulk water dams could be improved having been piped for at least 4 days.  This called for a mixing and aeration solution that would meet water quality requirements.  This was primarily focused on overcoming the Dissolved Oxygen depletion caused by the transit of the water, to prevent stagnation in the storage and reduce the risks of stratification and algae growth.  

    WEARS were selected by Jacob’s engineering after a stringent review and assessment to provide mixing to the Bulk Water storage lagoons. 

    The WEARS ResMix 1000 was chosen due to its ability to ensure algae management and dissolved oxygen parameters were met during typical operation providing superior whole of life outcomes. 

  • Effluent Tank Mixing – Changing the way effluent treatment tanks are mixed

    Two ResMix 1000 systems were deployed into tannery effluent treatment plant for use as the Mixers in an innovative, fully integrated biological and physical treatment plant.

    Tannery operations traditionally use high amounts of water and chemicals in producing hides and skins for manufacturing or export.  This iterative production cycle means that Tanneries keep producing wastewater that is highly Alkaline and requires intensive and special treatment before it can be safely released or re-used. This poses a significant risk to the natural environment if not treated and then released appropriately. 

    This method of treatment is and Australian first.  The treatment process takes place in two effluent tanks through proprietary electrical reaction. The wastewater is highly viscous and full of organic solids with a pH of ~12-13. The treatment process relies on keeping these solids in suspension. 

    Traditional gantry mounted stirrers are not able to cope with the viscosity and the solids.  They are also very expensive to build, install, operate and maintain. This is the first time a WEARS mixer has been used in this application.  The ResMix 1000 systems are producing enough flow velocity to keep the wastewater in the tanks fully mixed. The Operation of the ResMix 1000 has been highly successful in mixing the tanks completely and keeping all of the solids in suspension within the tanks. 

  • Algae control and managing hot weather

    Yarra Valley Water ‘Aurora Recycled Water’ project has been consistently effected by issues associated with algal outbreaks. This has caused blocked filters and the potential for toxicity in water used for irrigation purposes.

    With these algal issues exacerbated the by warm weather and temperate conditions, WEARS Australia was chosen to provide a solution. WEARS provided consulting, design and installation of a ResMix 1000 in early November 2016. 

    This reservoir is subject to climate fluctuations, high concentrations of dissolved phosphorous leading to periodic outbreaks of cyanobacteria. 

    The WEARS ResMix 1000 was chosen due to its ability to mix the reservoir but also the designed diffusion system which ensures that bottom sediment was not re-suspended.
