Vipac provides air quality assessment services for councils, government departments, commercial industry, developers and contractors. The company has been involved in major urban developments and construction for the past 28 years, including mining, airport developments, rail and road transport systems and a range of manufacturing, processing and power generation industries. Vipac is an organisation member of the Clean Air Society of Australia and New Zealand.
Vipac’s engineers work closely with mine operators in the early stages of development and construction through to mining operations to ensure environmental issues are addressed and relevant standards met.
Services include:
• Environmental Impact Statements for presentation to statutory bodies and councils
• Community consultation and presentations at public meetings and provision of expert witness
• Full spectrum of monitoring, auditing, modelling, assessment, design and mitigation of all sources – blasting, mining and processing noise, blast and ground vibration as well as air, dust and atmospheric emissions and pollution dispersion
For accurately estimating pollution dispersion, Vipac applies both computational and physical modelling techniques, in the measurement and prediction of pollutants such as dust, odour or gases, and provides design advice where necessary to enable maximum economic advantages.
With the help of sophisticated computer programs, we offer:
• Modelling for large distance modelling (far-field dispersion) for complex and hilly terrain
• Simulation of fundamental fluid flow problems, including single and multi phase flows encountered in areas of air purification, air flow, mineral processing, air blast, combustion, burner design and operation analysis, turbo-machinery, erosion, environmental control, ventilation and safety
• Use of finely detailed wind tunnel models allowing investigations of highly localised flow fields around realistic model mine sites (near field dispersion)
• Vipac’s Boundary Layer Wind Tunnel where momentum and atmospheric velocity as well as aerodynamic interference effects can be measured
• On-site monitoring - validating both physical and numerical models, helping to identify trouble spots, establish strategies to minimise the impact of pollution and determine whether the applicable operational criteria or licensing conditions have been met
• Special exhaust gas emission tests to ensure that vehicle engines are optimally adjusted to emit the lowest possible pollutant levels into the environment - for the benefit of the environment, the customer and the manufacturer
• Investigation into internal aerodynamics and thermodynamics affecting structures such as tunnels, systems, and built environments, and monitoring for fluid flows
• Recommendations for ventilation, internal smoke control and pollutant capture from engine driven items and other pollutant sources to ensure safe discharge to atmosphere
