Pond treatment for protein rendering unit

Monday, 27 June, 2022 | Supplied by: Hydro Innovations

Craig Mostyn Group is one of Australia’s leading diversified food and agribusiness companies. Its protein rendering unit Talloman, a core division of the Craig Mostyn Group, started having issues with a treatment pond, so Plant Manager Carlos Mendes looked for a solution. He wanted a reduction in BOD, COD, NH3 and blue/green algae.

Hydro Innovations recommended a Gorman-Rupp 100 mm EchoStorm system, which comprised a Gorman-Rupp U4A60S-B self-priming pump that powered a Gorman-Rupp EchoStorm VA4 venturi aerator.

The pump draws water from the lagoon, pumps it through the EchoStorm unit, drawing in air, mixes it with the water and delivers it back to the lagoon. The unit ‘saturates’ the water with dissolved oxygen, ‘conditions’ it and breaks down organic matter. This ruptures vacuoles within the blue/green algae, sinking it, depriving it of the sunlight required for growth.

The results

Mendes tracked the progress of the EchoStorm by measuring the total taxa. When the unit was installed in March, total taxa measured 217,000. Mendes stopped measuring when the last reading in May measured 6630 (a reduction of 97%). 

Mendes and the Talloman team are happy with the results.

EchoStorm aerators are available in sizes from 2 through to 6″.
