“All our lives have been impacted by COVID-19, however maintaining ani- mal welfare and food pro- duction amidst COVID-19 disruptions is critical and important to all Austral- ians,” Dr Schipp said.
Australia’s chief vet- erinary officer Dr Mark Schipp said World Vet- erinary Day was a time to recognise the longstand- ing dedication of this pro- fession to safeguarding animal and human health.
“Earlier this year our veterinarians stepped up in response to bushfires leading treatment of live- stock and wildlife.”
their continued work in identifying, preventing and responding to the increasing threat of dis- eases, including those spreading from animals to humans.”
“The continued dedica- tion of veterinarians has ensured that animals have been protected, and the world-leading reputation of Australia’s food pro- duction system remains as strong as ever.”
“Australia’s veterinar- ians improve the welfare of our animals, the pro- ductivity of our farms and the well-being of Austral- ians,” Dr Schipp said.
The continuing work of veterinarians has been particularly important during the COVID-19 pandemic, including vet- erinarians involved in re- search.
The first stage of testing potential vaccines against COVID-19 has already commenced.
The spread of the COV- ID-19 virus is being driv- en by person-to-person contact.

A MEAT process plant needed aeration to re- duce odours associated with its wastewater treat- ment system.
are collected and smashed through the pump and aerator, reducing their size and making them more available for biologi- calreaction.
The plant had a large 350,000-litre tank with in-flows exceeding four megalitres per day.
The plant has found the system very easy to ac- cess for monitoring and maintenance because it is located outside the tank (not in it or on it).
The owners also wanted a system that was easy to maintain and safe for operators.
Therefore no lifting ap- paratus is needed to ac- cess equipment, and there is no ‘working over water’ or ‘working at heights’ to contend with or write up on risk-assessment docu- ments.
Engineers at the plant selected a venturi-aeration system that consisted of two VA-1100 (6”) ventu- ri-aerators, powered by two Gorman-Rupp pump model V6A60-B pumps with a combined dis- charge rate of 140 litres per second.
Hydro Innovations re- gional manager Shaun Allgood visited the plant and noted everything had been installed and was functioning perfectly.
The Gorman-Rupp pumps draw the waste- water from the tank and discharge it at pressure into the venturi-aerators.
A spokesperson from the plant said they had no problems at all with the system.
Air is drawn into the aerator at a ratio 2.2 times the pump flow, where it is mixed with the waste- water.
Shaun will continue to stay updated on this project and provide assis- tance when needed.
Water is then discharged back into the tank, where ‘hydraulic sheer’ facili- tates the release of soluble gasses and volatiles from the water, which is now saturated with dissolved oxygen.
Smaller projects are possible with the use of smaller venturi-aerators, which are available in 50mm, 80mm, 100mm and 150mm sizes.
The discharge ports of the two aerators were set up tangential to the side wall to induce a ‘spin’ to the contents of the tank, causing solids to migrate to the centre where the pump suction lines were positioned.
Larger projects are ap- proached by using mul- tiples of the larger unit, sometimes using a dedi- cated large pump to ‘drive’ two, three or even four venturi-aerators.
