Case Study: Alumina Refining Industry – India

Growth of India’s alumina refining industry is driven by rapid industrialization, and increased demand from key sectors like construction, aluminum production, renewable energy, and infrastructure development. A leading alumina refinery was looking for a high-performing disc filter cloth to meet the need for increased throughput and turned to Cleanova Micronics for a more robust filter media solution than had been in service.

Challenge

A leading alumina refinery in India approached Cleanova Micronics seeking a higher-performing disc filter media than what their incumbent supplier was delivering. Their primary goals were:

  • Ramp up alumina production throughput without incurring significant increases in cost per tonne.
  • Achieve longer cloth service life, reducing frequent change-outs.
  • Reduce filtrate solids in the mother liquor, directly improving yield and refinery efficiency.

 

The refinery needed a filter cloth solution that could reliably deliver higher output and reduced downtime, while ensuring better control of filtrate solids.

Solution

PrimaDisc™ filter media was selected to meet the refinery’s performance objectives.

PrimaDisc™ has been successfully applied in alumina refineries worldwide since 1995 – including the UAE, Brazil, and Australia – and is engineered to deliver superior resistance to harsh chemical and mechanical environments.

By switching to PrimaDisc™, the refinery realized measurable operational improvements:

  • Up to 35% increase in filter cloth service life, as compared with the incumbent supplier.
  • Reduction of filtrate solids by 70%,  ultimately improving the alumina-to-caustic ratio of the mother liquor.
  • Improved alumina yield per tonne of bauxite processed, lowering cost per tonne.
  • Reduction in unplanned downtime due to fewer cloth failures and changeouts.
  • 35% decrease in maintenance costs through extended operating intervals.
