We originally specified two floating jet-venturi aerators to replace a single 30 kW traditional low-speed mechanical (LSM) surface aerator at Tatura WMF; due to the fact that the original aerator had failed and we needed something straight away,
we used Andzac’s test unit on an 8 metre cable only about four metres from the bank (in a 1.5 ha lagoon!). We noticed the difference within just a few days.
After running the single 2.2 kW Andzac test unit for a few weeks (correctly positioned) we ran a trial that showed we were getting similar COD results to the parallel lagoons (each with 30 kW aerators running 24/7) with significantly higher DO – average >2 mg/l compared with <1 mg/l in the parallel lagoons.
As the second Andzac unit wasn’t really needed at Tatura we installed it at Kyabram WMF where an old 11 kW LSM aerator had failed. Given the size of the lagoon (57 ML, 3 ha) we were planning to operate the 2.2 kW Andzac unit in parallel with the other (operational) LSM for enhanced mixing; after a week or so we ended up switching off the LSM aerator as our DO was well over 2 mg/l. In all we’re looking at saving over 600,000 kWh/y in aeration at both sites (around $80k p.a. all up).
The one thing that has made this easy for us is how accommodating Andzac Water Treatment has been through the whole process – nothing has been too much trouble and Andrew has been available at the drop of a hat. Similarly, generously allowing us to test the technology risk-free has really made this an attractive proposition.

GVW recently encountered issues with higher than normal levels of ammonia within a raw water storage. The aerator was installed in an attempt to reduce the ammonia concentrations. The aerator was installed at the start of July 2016 and as shown in the graphic below the ammonia levels began to reduce. One additional benefit of this particular aerator is the low energy usage and also the low noise emissions. The storage is within a residential area and as such noise was a big consideration.

Since installing the Andzac aerator in our 7.5 ML wastewater dam in June 2018 we have seen a dramatic improvement in the quality of the water we are irrigating.
Prior to installation the dam was a sickly dark grey in colour and odour was constant issue. As well as this there was also a thick layer of sticky white foam that covered most of the water surface.
We now have no odour issues from the dam and no foam either.
The aerator has been running 24 hours a day for 7 days a week since it was installed and has not missed a beat.
Overall the Andzac aerator has delivered on the performance and reliability we were promised.
