Leachate treatment plant success for Shellharbour City Council – Article in Waste Management Review

Aerofloat’s design at Dunmore Leachate Plant for Shellharbour City Council allowed for increases in flow rates and ammonia concentration during peak flows. The plant achieved results beyond the initial scope, managing peak loads of 2000mg/L of ammonia and still achieved strict Sydney water ammonia and nitrogen discharge limits.

Shellharbour City Council’s facility at Dunmore needed to reduce operational and waste disposal costs, leading to the commission of a report to look at alternative options to its current offsite treatment arrangements. Aerofloat’s experience and foresight in wastewater treatment ensured it won the tender to work with Shellharbour Council’s leachate treatment plant in Dunmore.

Leachate produced from the Dunmore Recycling and Waste Deposit Depot had historically been collected in 200,000L of onsite tanks. This was then disposed of via onsite irrigation, or via third-party offsite treatment. The commissioned report showed that onsite pre-treatment and connection to sewer would be reduce costs for the facility.

Aerofloat was awarded the contract after a vigorous selection process. The foresight of Aerofloat’s Managing Director Ray Anderson when reviewing the design of the system ensured Aerofloat’s selection.

“I anticipated there would be more nitrogen in the future and it wouldn’t cost much more if we modified the design to account for this from the start,” said Anderson.

“Which, as it turns out was a good move, as the concentration changed throughout the course of the project but design changes were not necessary half way through the project.”

“We are often a little bit more conservative with our designs. The plant was designed for 65m3 per day, with an average ammonia concentrate of about 1250mg/L. The testing that we have been doing over the past few weeks of commissioning has shown it has been up around the 1500 to 1800mg/L, or up to 50 per cent higher than the original design concentration. Due to our conservative design, the plant has the capacity to handle this higher load.”

Once the civil works and large tanks were constructed, Aerofloat made the build seem simple, despite being a very complex project. Completing the project ahead of schedule enabled council to commence discharging treated effluent to sewer much sooner than expected. Needless to say they were satisfied with the result.

Aerofloat’s innovative technology reduces costs whilst ensuring a robust and sustainable solution. Contact Aerofloat’s engineers to discuss your leachate, sewage and wastewater treatment requirements.
