Queensland Rail is committed to ensuring that rail remains Australia’s most environmentally sound method of large-scale transportation. The lead-contaminated water produced from Queensland Rail’s railway bridge maintenance was being released into the surrounding environment, which posed a potential risk.
To minimize their environmental impact and as part of their internal water conservation campaign, Queensland Rail commissioned Virotec utilising the benefits of ViroFlow™ Technology.
For four months Virotec collected the wastewater in a holding tank where it was then transferred via a vacuum tanker to an off-site treatment facility where ViroFlow™ Technology utilising MetalLock™ reagent was applied. MetalLock™ effectively removes all soluble lead from the wastewater, and forms a dense solid precipitate that can be classed as an “inert”. The result is treated water that is free from lead and other heavy metal contaminants.
The treated water is later re-used for beneficial purposes. Specifically, the treated water (after validation) is used at a local composting facility as an essential ingredient for the composting process. The re-use effectively lowers the need for external water to be used.
ViroFlow™ Technology can be easily integrated into any aquatic system for the effective removal of lead and other heavy metal contaminants in an environmentally friendly and cost-effective application.
