The Tasman Tank Co.  recently supplied six sealed panel tanks and three membrane lined tanks for a state-of-the-art water recovery plant at the Bluetongue Brewery located on NSW’s Central Coast.  

The $120 million brewery on NSW’s Central Coast incorporates a state-of-the-art water recovery plant, which also provides renewable energy for the brewery, reducing its dependence on fossil fuels.  

The water recovery plant was installed by a partnership of CST Wastewater Solutions and Global Water Engineering (GWE). Tasman Tanks was selected as the tank, digester and liquid storage fabricator and constructor by CST and GWE to deliver and install the storage solutions for Bluetongue.  

The nine storage solutions utilise Tasman’s advanced coating and membrane liner technologies, and include six FBE (FUSION 7000) sealed panel tanks for unmatched coating performance as well as three membrane-lined tanks for a highly cost-effective storage solution for the wastewater system.  

The six FBE panel tanks have a highly advanced coating system from Tasman Tanks’ affiliated group Tank Connection.  

Tank D101 at Bluetongue is a 687,000-litre fully sealed anaerobic methane reactor tank. Biogas is produced when the bacteria breaks down the organic matter within the wastewater. This biogas is captured and reused as renewable energy to power the brewery boiler.  

The need for large capacity industrial tanks for food and beverage applications is being driven by the demands of technologies involving zero discharge applications.  

Vital to environmental and process requirements, these applications include methane capture, biogas capture, anaerobic and aerobic process, ultrafiltration, steam and demineralised water used for turbine cooling among others.  

Multiple tanks may be required in large products to manage multiple applications and include bulk storage tanks, intake tanks, flocculation tanks, filtration tanks, mixing tanks, balance tanks, disinfection tanks, chemical tanks and settling tanks.  

Bolted steel tanks offer advantages such as cost-efficient size potential and the ability to isolate diverse liquids through advanced coatings that will not react with contents over time.  

Fusion bonded coating systems such as those developed by the internationally respected Tank Connection group and Akzo Nobel are integral to the effectiveness of zero discharge applications.  

These factory-applied coatings are particularly suited to totally sealed applications where all the liquids involved in a process are retained on-site.  

Tank Connection’s fusion coated tank systems include LIQ Fusion 7000 FBE coating, which is approved for potable drinking water with NSF-61 international standard approval.  

Key advantages of LIQ Fusion coating: 

  • Does not spall or crack
  • Holiday-free coating for total coverage without blemishes, pinholes or protective flaws
  • Fusion bonded to substrate surfaces to give total coverage
  • Electrostatic powder-on-powder application provides complete wraparound on panel edges and in bolt-holes
  • Fusion FBE can be repaired
  • Does not require costly and potentially troublesome cathodic protection

Protective fusion bonded coatings have been used in the tanks at the Bluetongue facility. Tanks incorporating such protection are also highly applicable to Alternative Waste Treatment facilities (AWTs), a major global industry with plants now being constructed extensively throughout Australia and Europe.  

AWTs employ factory coated fusion bond systems for the bolted tank construction of digesters and liquid storage. An AWT can have up to 9-11 tanks for the entire treatment process.  

Bluetongue Brewery incorporates strict environmental standards and is designed to deliver world-class water and energy savings, says the CEO of Pacific Beverages, Mr Peter McLoughlin.    

Mr McLoughlin says that the plant has been able to target a reduction in water usage to 2.2 litres per litre of beer produced, using water recovery techniques and modern design principles.  

Additionally, methane from this process will also power a third boiler, which will reduce Bluetongue’s energy consumption by about 15 per cent.  

Mr Aldridge of Tasman Tanks says that big tanks may hold upwards of 10, 20 or even 30,000 tons of often very valuable or sensitive liquid, making it important to understand the advances in protective coatings such as those used in the Bluetongue reactor.
