A large regional council needed to develop a system to effectively treat leachate from their Landfill Waste Facility so it could meet discharge requirements to sewer.
‘The Gorman Rupp Echo Storm aerators and Gorman Rupp self-priming pumps allows the system to deliver the required dissolved oxygen using less power than the alternative floating aerators’.
The Problem
The leachate was managed on site by recirculating and spraying for dust suppression at the Waste Facility. However, the volume of leachate being generated has increased to such a level that this approach was no longer feasible. There was also odour concerns associated with this approach.
The Solution
A fill and draw sequencing batch reactor (SBR) system was constructed using the existing leachate dams. It was decided that bank mounted aeration using Gorman Rupp self-priming pumps and Gorman Rupp Echo Storm aerators was the best solution for the treatment of the leachate. This system is used to mix in one phase and aerate in another phase using the same pumps and pipework, all done automatically using the control panel. Using Gorman Rupp self-priming pumps and careful placement of the suction and discharge lines allows for excellent mixing and aeration of the entire contents of the dam.

The Pumps
The Gorman-Rupp Super T Series self priming centrifugal wastewater/sewage pump has been the world benchmark for this technology since 1963 (over 50 years!). They have been designed for economical, trouble-free operation, with superior solids handling capability and a large inspection cover to access pump internals for service or blockage removal.
