Award winning Kingaroy Wastewater Treatment Plant officially opens

Posted: 27 Apr, 2017

The Aquatec Maxcon designed and constructed Kingaroy Wastewater Treatment Plant, owned and operated by South Burnett Regional Council, was officially opened on Monday 25^th April.

The plant, which was completed in early 2016, has been operating without a hitch for a year and is the first of its kind within Australia to use ground-breaking Nereda® technology, developed by the Dutch company Royal HaskoningDHV.

The innovative Nereda® system uses granular activated sludge (biomass) to treat all of the town’s wastewater, which significantly reduces the need of chemicals and dramatically reduces the plant’s energy requirements. This technology purifies wastewater and sewage into quality Class A+ recycled (drinking) water, surpassing official effluent standards, which can then be used for irrigation or released safely back into the environment.

South Burnett Mayor Keith Campbell said the old trickling filter sewage plant had been long overdue for replacement and the local environment had also been “crying out for a break” from low quality effluent.

Aquatec Maxcon Managing Director, Greg Johnston, said the significance of the project could not be overstated with the operating costs now 45% less than a plant using conventional technology. Mr Johnston continued to say “Effluent discharged from the Nereda® reactor is suitable for recycled water reclamation, so during the summer months up to half of the influent is going to be reused for local sports facilities – an excellent result for the local community. Nereda® technology is new to Australia but is being used all over the world. I believe it sets a new standard in the biological treatment of wastewater.”

The $25 million plant, built on time and within budget, won the 2016 Engineering Excellence Award for Projects over $10 million.

Black Gully Wastewater Treatment Plant

Posted: 17 Mar, 2017

Aquatec Maxcon are pleased to announce our appointment to deliver the new Black Gully Wastewater Treatment Plant (10 000 EP) in Emerald, Queensland for the Central Highlands Regional Council (CHRC). This award offers Aquatec Maxcon the opportunity to continue our long term involvement and support of the site, having supplied the existing surface aerators 20 years ago.

Aquatec Maxcon will be delivering the plant including all civil, mechanical and electrical components of the project which includes inter alia; inlet works, bioreactor, clarifiers, disinfection and associated pump stations, as well as the new waste sludge handling stream, including pre-thickening, aerobic digestion and new sludge drying beds to augment the existing plant.

This award confirms Aquatec Maxcon’s capability and reputation to deliver regional treatment solutions, being of similar scope and nature to projects commissioned in 2016;

Chinchilla STP (10 000EP) for Western Downs Regional Council and
Kingaroy STP (12 500EP) for South Burnett Regional Council.

Aquatec Maxcon appreciates the opportunity to cater for the recent growth in Emerald, and looks forward to a successful partnership with CHRC, CH2M and local businesses to deliver this solution.

Aquatec Maxcon awarded Refurbishment Contract for Wahgunyah Water Treatment Plant, VIC

Posted: 16 Mar, 2017

Aquatec Maxcon has a strong reputation within the water and wastewater industry for implementing innovative, world class water solutions, in particular to brownfield projects.

Our design team has developed a unique, innovative solution which makes the best use of the existing site and equipment, to deliver a cost effective solution for the refurbishment of the ageing Wahgunyah Water Treatment Plant (WTP), in Victoria. The Wahgunyah township is located on the Southern Bank of the Murray River, opposite Corowa in New South Wales.

The existing filtration plant is unable to cope with recent raw water excursions, particularly related to colour and turbidity. Hence, North East Water have made a decision to convert the Water Treatment Plant to a Dissolved Air Floatation (DAF) process to ensure a reliable water supply can be provided to the township of Wahgunyah in the future. The scope includes re-using raw water pumps, diverting raw water to a new flocculation tank, a new DAF injection manifold, cutter sprays and new DAF recycle pumps and modifications to the existing roof structure.

The interfaces will be managed efficiently by our project team to ensure that no disruptions to the water supply at Wahgunyah occur.

Aquatec Maxcon awarded the UV Design and Supply contract for Moe Wastewater Treatment Plant

Posted: 15 Mar, 2017

Gippsland Water have awarded the contract at the Moe Wastewater Treatment Plant to Aquatec Maxcon for a new UV system from Trojan UV3000™plus. Our solution provides the best Whole of Life cost.

The UV3000™ Plus has low pressure lamp UV disinfection using energy efficient, high output Amalgam Lamps (250W). The system features variable output lamp/ballast and electronic ballasts which enable the lamps to be driven at variable power settings, dependent of flow or effluent quality. Subsequently, as flow increases or decreases, the power to the lamps will adjust proportionally. As effluent quality improves (UVT%) the power settings are also automatically adjusted. This eliminates the need for lamp/bank, on/off switching and provides more efficient control power usage. The UV system will maintain continuous target disinfection due to inclusion of an automated cleaning system.

The contract also includes disconnection, decommissioning and demolition of the existing UV reactor which could not deliver the required disinfection targets.

Aquatec Maxcon awarded the Operations and Maintenance Contract for Re-waste Facility No.1 at Aurora Sewage Treatment Plant

Posted: 14 Mar, 2017

Aquatec Maxcon were engaged to design and construct the Re-Waste Facility No.1 linked to the Aurora sewage treatment plant (STP) in 2014.

Our unique design solution diverts 33,000t of commercial food waste from landfill each year. This generates enough biogas to power the existing Aurora STP and recycled water facility with surplus energy (approx. 78%) to be sold or exported to the electricity grid. The facility is now nearing final testing in March 2017, and the plant is providing surplus biogas to the gas engines at the Aurora plant.

Re-Waste Facility No.1 has had an operations team running the facility since mid-2016 whilst organic wastes are delivered to the site. Aquatec Maxcon has been awarded the operations and maintenance contract for a period of two (2) years, with an extension if the facility continues to operate effectively.
