Chicken Process Plant
Simple Venturi Aeration reduces odours at wastewater treatment system
A chicken process plant in South Australia needed aeration to reduce odours at their wastewater treatment system. The plant had a large 350,000 litre tank, with in-flows exceeding 4 megalitres per day. They also wanted a system that was easy to maintain and safe for operators.
We are very happy with the Venturi system and its odour reducing capabilities
– Spokesperson from the plant
Engineers at the plant selected a Venturi-Aeration system. It consisted of two VA-1100 [6”] Venturi-Aerators, “powered” by two Gorman-Rupp pump model V6A60-B. The combined discharge rate is 140 litres per second [L/s]. The Gorman-Rupp pumps draw the wastewater 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 discharged back into the tank, where “hydraulic sheer” facilitates the release of soluble gasses and volatiles from the water. The water is now saturated with dissolved oxygen.
The discharge of the two aerators were set up tangential to the side wall to induce a “spin” to the contents of the tank. This causes solids to migrate to the centre, where the pump suction lines were positioned. This way, large solids are collected, smashed through the pump and aerator, reducing their size and making them more available for biological reaction.
Hydro Innovations Regional Manager, Shaun Allgood recently visited the plant. Shaun noted that everything had been installed perfectly and was operating very well. A spokesperson from the plant said they were very happy with the system and its odour reducing capabilities.
The plant has found the system very easy to access for monitoring and maintenance. Because it is located outside of the tank [not in it or on it], there is need no lifting apparatus to access equipment. 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. 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-Aerators.
The Gorman-Rupp Ultra V Series is the most advanced self priming centrifugal wastewater and sewage pump range on the market today. They are high performance, high head, and high efficiency pumps, designed to deliver a long and low maintenance service life, with low cost of ownership.
The Venturi Aerator features a classic design for modern applications. Whether you need a complete replacement or simply an enhancement to your existing system, the Venturi Aerator offers an innovative and convenient approach to your aeration needs.
The EchoStorm water aerator from Gorman-Rupp offers the benefits of safety, reliability and ease of access to water aeration applications.
Because these units are mounted on the bank [instead of floating on the water or being submerged in it], access is much less complicated and safer, while delivering oxygen transfer outcomes.
The EchoStorm water aerator benefits::
- No cranes or row boats for maintenance
- Easily accessed
- Less downtime
- Reliable and easy to maintain
- Easily scalable and low cost of ownership
- Thorough mixing – no dead spots
- High SOTR (Standard Oxygen Transfer rate)
- Oxygenated water
These aeration units are used in conjunction with Gorman Rupp self-priming centrifugal pumps to deliver solutions for the following applications:
- Lagoon and basin water aerator
- Oxidation ditch aeration
- Lake destratification and algae control
- Odour control
- Sludge digestion
- Septage treatment
