Hospitality industry downturn vs high home cooking demand
DEMAND for eggs is high with the great home-cooking happen- ing, yet many farm- ers are affected by the downturn of egg use in the hospitality industry.

The egg industry has worked with government at state and federal levels in relation to a range of issues.
Thank you to those people who have made contact in relation to re- spective issues – this has ensured engagement with authorities was informed with examples.
Issues included future demand for grain supply from intensive industries in the coming months, the impact of COVID-19, spent hens, the increase in insurance costs, invest- ment in the egg industry and the needs of the la- bour force into the future.

to stay updated on this project and provide as- sistance when needed.
The plant had a large 350,000-litre tank with in-flows exceeding four megalitres per day.
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.
Therefore no lifting apparatus is needed to access equipment, and there is no ‘working over water’ or ‘working at heights’ to contend with or write up on risk- assessment documents.
Smaller projects are possible with the use of smaller venturi-aerators, which are available in 50mm, 80mm, 100mm and 150mm sizes.
The owners also want- ed a system that was easy to maintain and safe for operators.
This way, large sol- ids are collected and smashed through the pump and aerator, re- ducing their size and making them more available for biological reaction.
Hydro Innovations re- gional manager Shaun Allgood visited the plant and noted everything had been installed and was functioning per- fectly.
Larger projects are approached by using multiples of the larger unit, sometimes using a dedicated large pump to ‘drive’ two, three or even four venturi-aera- tors.
Engineers at the plant selected a venturi-aer- ation system that con- sisted of two VA-1100 (6”) venturi-aerators, powered by two Gor- man-Rupp pump model V6A60-B pumps with a combined discharge rate of 140 litres per second.
The plant has found the system very easy to access for monitoring
A spokesperson from the plant said they had no problems at all with the system.
More information can be obtained by emailing info@hydroinnovations. com.au
The Gorman-Rupp pumps draw the waste- water from the tank and discharge it at pressure into the venturi-aerators.
Air is drawn into the aerator at a ratio 2.2 times the pump flow, where it is mixed with the wastewater.
Water is then dis- charged back into the tank, where ‘hydraulic sheer’ facilitates the release of soluble gas- ses and volatiles from
