Hydroflux to Deliver Thermal Drying Technology to The Sludge Minimisation Facility of Wellington City
February 8, 2024
Hydroflux has been awarded the Thermal Dryer Package for the new Sludge Minimisation Facility of Wellington City. Recently the McConnell Dowell-HEB Joint Venture was awarded a contract to construct the new Facility.
The new Sludge Minimisation Facility will reduce sludge volumes by up to 80% which will significantly reduce carbon emissions compared to the current disposal to landfill and also allow the sludge to be used in sustainable ways such as soil conditioner and fuel for industrial heat. The process will include advanced thermal hydrolysis, anaerobic digestion, dewatering and thermal drying.
Hydroflux Epco NZ were awarded the design and delivery of the thermal dryer, which will dry all the digested sludge post dewatering. A HUBER BT12 Belt Dryer was selected for the process.
“We are pleased to be involved in this groundbreaking project which will result in significant environmental benefits, such as reduced waste and carbon emissions. The benefits include reduced biosolids disposal costs, greater reuse opportunities of the final dried product, exploitation of waste gas, and the associated sustainability outcomes” says Orod Roostaee, General Manager of Hydroflux New Zealand.
HUBER SE are global leaders in the design and supply of solids liquid separation technology and thermal dryers. Hydroflux are the exclusive agent for HUBER throughout Australia and New Zealand. Currently HUBER are supplying numerous belt dryers to projects in Europe, Middle East and USA.
“Biosolids management is a key topic around the world. Some nations have moved towards centralized digestion with hydrolysis pre-treatment to exploit higher gas yields and green energy. Others have mandated fertilizer recovery from sewage biosolids using thermal treatment.
Regardless of which path is taken, exploiting the hidden energy potential of biosolids is common. HUBER are currently delivering some of the largest drying projects in the world, in countries such as Germany, Netherlands, Belgium, USA and now New Zealand.
Biosolids resilience is a key topic amongst many of our customers in New Zealand and Australia, so it’s great to see such an innovative project come to life” says John Koumoukelis, CEO of Hydroflux.
