Bird in Hand Wastewater Treatment Plant DigesterBird in Hand Wastewater Treatment Plant


For the Bird in Hand project EPCO designed and supplied the digester system which compromises sludge heating, sludge mixing with gas lances and a mobile gas holder roof. The mobile gas holder roof collects methane gas and uses it for heating the sludge via a boiler. The unique thing about this site is that we were not allowed to physically flare the waste gas and had to capture the excess that wasn't used for heating.

As there were concerns over the potential for bushfires in the area the system had to be designed so that the excess gas would be used to heat the water which would in turn go through a cooling radiator and circulate back through the digester system. The digester uses microorganisms to break down the biodegradable material in the treatment plant.

In this system the sludge comes to the digester tank on top of which is a mobile roof. The gas emitted by the digestion process builds up a pressure under the mobile roof so it can be moved to the water heating unit. The whole system is self-generating.

Mt Morgan Mine Water Treatment PlantMount Morgan Mine Water Treatment Plant

 

EPCO Australia was awarded the contract for the upgrade of the Mount Morgan lime dosing water treatment plant. The existing plant is situated at the former Mount Morgan Mine. It captures water stored on the mine site and treats it before releasing it into the Dee River.

The upgrade has increased the facility's water treatment capacity by 50%, from two megalitres per day to three megalitres.

The upgrade is part of the Queensland state government's Mount Morgan Mine Rehabilitation Project.
 

Burpengary East Sewage Treatment Plant ClarifierBurpengary East Sewage Treatment Plant

 

EPCO Australia was recently awarded the contract for the design, supply, installation and commissioning of a peripheral drive thickener clarifier as part of Unity Water's Burpengary East sewage treatment plant upgrade. The Burpengary project will convert and upgrade existing sewerage treatment works increasing capacity to an equivalent population of 49,000. It will also improve the quality of the treated wastewater discharged to the Caboolture River.
 

Northern Water Treatment Plant ClarifierNorthern Water Treatment Plant


EPCO Australia was awarded the contract for two 10m diameter thickener clarifier mechanisms which were part of the construction of the new Northern Water Treatment Plant at  Eurobodalla on the New South Wales south coast. The Eurobodalla Shire has a permanent population of 33,000 with typical water use of 11 million litres per day. During the peak tourist season, water use can rise to as much as 18 million litres per day.

The new plant will treat 20 million litres of water per day and can be upgraded to treat 30 million litres per day in the future.

Raymond Terrace Wastewater Treatment Plant ClarifierRaymond Terrace Wastewater Treatment Plant

 

An upgrade of Hunter Water's Raymond Terrace Wastewater Treatment Plant gave EPCO the opportunity to work with Gongues Construction, the main contractor for the project. EPCO Australia was awarded the contract for a new 23m diameter peripheral drive clarifier as well as the diffusers and blowers for the upgrade to the aeration system.

The upgrade has increased the capacity of the Raymond Terrace WWTW plant to cater for 35,000 people.
