NT alumina refinery - case study
Red-mud pond dewatering system for an alumina refinery in Australia’s Northern Territory.
XPEL supported an alumina refinery in the Northern Territory, Australia, that needed a sustainable way to reduce excess water stored in its red-mud ponds. We deployed a large-scale evaporation package built around our 200/100 evaporator units, designed to stabilize pond levels and support continuous refinery operations.
The 16 x 200/100 evaporation systems package provided a combined volume throughput of 3,200 GPM (720 m³/hour), enabling rapid and consistent water reduction across the red-mud storage areas. This performance reduced environmental risk, supported compliance, and strengthened the refinery's overall operational stability.
Advanced Water Evaporation Systems for alumina refining by XPEL.
This refinery managed significant volumes of process water and residue liquids stored within red-mud ponds. Rising water levels placed pressure on storage integrity, created environmental exposure risks, and added operational strain. XPEL advanced mechanical evaporation systems offered a practical way to reduce stored water quickly and maintain safe operating conditions across the refinery.
In this project, 16 XPEL evaporators delivered 720 m³/hour of evaporation capacity. This evaporation output helped the refinery maintain safe pond levels, reduce environmental exposure, and support stable day-to-day operations.
Engineered reliability delivered by XPEL.
Large-scale water reduction: Multiple XPEL evaporators delivered strong throughput across large red-mud pond areas. This capacity supported predictable and efficient dewatering.
Operational stability: Consistent evaporation helped maintain safe storage conditions and reduced strain on refinery operations.
Environmental compliance: Lower stored water volumes reduced environmental exposure and supported regulatory requirements for residue management.
