Aqua-Audit Services: Since its establishment in 1999, Aqua-Audit has conducted on-site tests on over ninety wastewater treatment plants in Australia and New Zealand. Many of these plants are now tested on an annual basis.

The most frequently used services are:

  • Backpressure monitoring;

  • Off-gas testing; and

  • Acid vapour cleaning.

Aqua-Audit also conducts on-site SOTR testing from time to time, as well as full aeration system analyses. Energy efficiency audits and plant optimisation services offer particularly cost-effective returns.

In the course of the last 20 years, Aqua-Audit’s principal, Tom Lawson, has conducted tests on almost every type of diffuser in common use in Australasia. The inventory of results he has accumulated during this period provides a valuable resource against which to compare the data for each new plant tested.

Before founding Aqua-Audit Tom Lawson spent more than 15 years designing, supplying and conducting acceptance tests on a wide variety of aeration systems. He founded Aquatec Engineering in 1981, and was managing director of Aquatec-Maxcon from 1985 to 1997. He was involved in research and product development during much of this time, and successfully applied for patents for Aquatec-Maxcon’s AquaStar surface aerator and AquaBlade membrane diffuser.
