Chicken process plant reduces odours with safe aeration tech
A CHICKEN processing plant needed aeration to reduce odours associated with its wastewater treat- ment system.

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 ven- turi-aerators.
The plant had a large 350,000-litre tank with in- flows exceeding four meg- alitres 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, caus- ing solids to migrate to the centre where the pump suc- tion lines were positioned.
sistance when needed. Smaller projects are pos- sible with the use of smaller venturi-aerators, which are available in 50mm, 80mm,

The owners also wanted a system that was easy to maintain and safe for op- erators.
This way, large solids are collected and smashed through the pump and aera- tor, reducing their size and making them more avail- able for biological reaction.
100mm and 150mm sizes.
The Gorman-Rupp pumps draw the wastewater from the tank and discharge it at pressure into the Venturi aerators.
Engineers at the plant se- lected a Venturi aeration system that consisted of two EchoStorm 6” Venturi aerators, powered by two Gorman-Rupp pump mod- el 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 and mainte- nance because it is located outside the tank – not in it or on it.
The Gorman-Rupp pumps draw the wastewa- ter from the tank and dis- charge it at pressure into the Venturi aerators.
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 documents.
Air is drawn into the aerator at a ratio 2.2 times the pump flow, where it is mixed with the wastewater.
Hydro Innovations re- gional manager for South Australia visited the plant and noted everything had been installed and was functioning perfectly.
Water is then discharged back into the tank, where ‘hydraulic sheer’ facilitates the release of soluble gasses and volatiles from the wa-

RUGGED & RELIABLE WASTEWATER PUMPS
• Self Priming Pumps are mounted above ground for easy access and
maintenance
• Designed to minimise blockages
•Pumps rags and stringy materials with ‘eradicator’ technology
• Does not require multiple personnel to maintain.
