Aerators in Action: Myrtleford Victoria
The issue The town's sewage and also the effluence from a paper mill were being discharged into a primary and secondary lagoon system. The water surface of the primary lagoon had become covered with a floating fibrous mass and a serious odour problem existed.
Aerators in Action: Myrtleford Victoria
The solution: By-Jas Engineering provided an installation consisting of six 15kW aerators. The units were brought into use in 1975 and are still in use today.
Aerators in Action: Myrtleford Victoria
The result: In less than 3 weeks the floating material had disappeared and with it the unpleasant odour.
