Filter for cooling water treatment

Optimized cooling water treatment for aluminium rolled products

Find out how our state-of-the-art filtration solutions effectively combat corrosion and deposits in the cooling circuit at a manufacturer of rolled aluminum products and reduce operating costs.

Challenges in cooling water treatment

Corrosion, deposits and abrasive wear are well-known problems in the cooling circuit of aluminum rolling mills. These arise from the complex interaction of various substances in the cooling water and the materials of the system components.

Solution: Automatic backflush filters from GEFA

Our automatic backflush filters are the ideal solution for water treatment in aluminum rolling mills. They replace conventional sand filters and impress with their efficiency, reliability and space-saving design.

Functionality and advantages

  • Effective filtration: The filters reduce solids in the selected separation size and thus significantly improve the cooling water quality.
  • Low maintenance: Filtration reduces the load on downstream system components such as plate heat exchangers, nozzles and mechanical seals, which reduces maintenance costs.
  • Space-saving design: Compared to conventional sand filters, our backwash filters require less space and are more economical to operate.
