Successfully Refurbished Digester at the Prince of Wales Bay STP

Aquatec Maxcon congratulates TasWater on the successful recommissioning of the refurbished Primary Digester at the Prince of Wales Bay Sewage Treatment Plant located in Tasmania. We are very proud to have been a part of this successful project which included the design and construction of a new floating digester gas holder roof and new sludge heating system.

Our Project Manager, Jim Foley, had the difficult task of delivering this project despite the impacts and challenges posed by COVID-19. We are extremely proud of our team’s ability to continually meet milestones and deliver results despite continued delays and complications as a result of the current global pandemic.

Aquatec Maxcon Provides Aid to India during Covid-19 Crisis

From 2013-2014, Aquatec Maxcon Asia, the Thailand manufacturing arm of the Aquatec Maxcon Group Limited, constructed 86 cryogenic iso transport containers for the shipment of industrial gases for its sister company, Cryeng Group Pty Ltd. The iso containers have a capacity of 20,000 litres and a pressure rating of 10 bar.

These tanks were used by Bechtel Corporation at its Gladstone liquefied natural gas plant construction site for customers, Gladstone LNG and Australia Pacific LNG.

These tanks have now been shipped to India to help in the transport of critical oxygen supplies to hospitals throughout India.

New Lamella Clarifiers: Douglas WTP Upgrade

Aquatec Maxcon is proud to be part of the delivery team for the Douglas Water Treatment Plant upgrade awarded by Townsville City Council. This is a $27.5 million expansion project involving the construction of two new lamella clarifiers, providing a reliable, compact, robust and low maintenance solution for reducing turbidity.

Aquatec Maxcon has access to one of the highest performing and reliable lamella clarifier systems in the world and have successfully designed and installed 20 lamella clarifiers across Australia and New Zealand. We are also pleased to continue our extensive history at the Douglas Water Treatment Plant which has included the design and construction of the lime silo and dosing system in 2009 with Trility and BMPX as well as carrying out filter media replacements.

In fact, Lawrence Cheung, the Construction Engineer on these past projects will now manage this project for us, bringing a wealth of historical knowledge to the team.

We look forward to working with BMD Constructions in delivering this upgrade for Townsville City Council.

Kingaroy's Nereda® WWTP has been operating for over 5 years!

Kingaroy Aquatec Maxcon Celebrating 5 Years

Aquatec Maxcon are proud to announce that the Kingaroy Waste Water Treatment Plant has been operating successfully for over 5 years!

In mid-2014, South Burnett Regional Council (SBRC) engaged Aquatec Maxcon to undertake the design and construct upgrade of the Kingaroy Waste Water Treatment Plant (WWTP). Aquatec Maxcon based its treatment solution on Nereda® technology and was awarded the contract. The project was the inaugural use of aerobic granular biomass technology, in Australia. Aquatec Maxcon was responsible for the process, civil, mechanical and electrical design, all site works and commissioning. The project was a major milestone for SBRC and was partially funded via the Queensland State Grants “Royalty for the Regions” program.

The plant has been fully-operational since the autumn of 2016. The effluent discharged from the reactor now provides the Kingaroy community with water via recycled water reclamation. During the summer months up to half of the resultant liquid is reused for sporting fields and a golf course in the vicinity. The process has also significantly improved the quality of effluent released from the plant, directly benefitting the local environment. The Nereda® process offers operational flexibility, as it can be tailored by adjusting its operable parameters to reflect changing conditions. At present, Kingaroy operates at a maximum of 1.9ML a day. In the event of a sudden population increase, another reactor can be installed, with the advantage that most of the supporting infrastructure is already in place.

For the 5 years of its operation, the plant has continued to provide better quality effluent than that required by its licence with the nitrogen, ammonia and phosphorous loads to the environment significantly lower than required.

Since its handover, Kingaroy WWTP has been solely operated by SBRC operators, notably Andy Watson who was awarded the best operator paper (co-authored by our very own Shay White) at WIOA QLD 2019 awards as well as special commendation for operator of the year at the WIOA QLD 2017 awards. Andy Watson operates the Kingaroy WWTP along with his fellow operators under the supervision of SBRC Water & Wastewater Program Coordinator, Adam Branch, and Engineer, Steve Carroll.

Royal HaskoningDHV, the technology supplier of Nereda®, were absolutely vital in the success of the tender and plant, including Rosalie Rosink, Arnold Zilverentant, Robbert van der Kuij and Arne Boersma.

The design of the Kingaroy WWTP was led by our Queensland State Manager and Nereda® Product Manager, Monita Naicker, who was pivotal in offering an alternate process solution to the preferred conventional oxidation ditch. As a result of SBRC choosing the Nereda® option, the Kingaroy Plant outperformed the energy guarantee during process proving by an impressive 30%! Andrew Chan was the Kingaroy commissioning manager, and he will soon be commissioning two more of Aquatec Maxcon’s brand new Nereda® systems, a 223,000EP plant in Quakers Hill, New South Wales, and a 20,000EP plant in Longford, Tasmania.

Aquatec Maxcon Asia: 440,000 Litre Cryogenic Tank

 tank chiyoda title image

The latest progress update from our Thailand branch - A 440,000 litre cryogenic tank under construction in Thailand for a LNG plant located in the USA.

A stainless steel inner vessel will be inserted in the mild steel outer vessel and perlite and vacuum insulate will be installed.

All of our tanks can be designed and manufactured to AS 1210, ASME VIII Pressure Vessel code, and any other applicable Australian & International Standards. Advanced design technologies allow accurate analysis of foreseeable operating conditions, including seismic and cyclonic wind conditions to AS 1170, transportation induced loading, normal & abnormal operating pressures, and the elements.

Our cryogenic tanks (cryogenic vessels, cryogenic surge drums, cryogenic pressure bullets) are manufactured to ISO9001 quality control procedures, with the following testing done on all cryogenic tanks fabricated by Cryeng Group (A member of the Aquatec Maxcon Group of Companies):

  • Full hydrostatic testing for Class 1, 1H, 1S, ASME VIII Div. 1 and Div. 2 inner vessels
  • Helium leak testing to verify vacuum integrity of inner vessel jacket
  • Soapy bubble testing of all cryogenic valves and external piping
  • Cold shock testing of inner vessels with liquid nitrogen for nozzle and pipe integrity check
