Backflush Filters

The BOKELA Backflush Filter is applied for clarification of high flow rates of low-concentrated process liquids. Main field of application is the clarification of aluminium hydroxide solutions in the Bayer process.


Typical applications are:

  • aluminium hydroxide as basic material (smelter grade alumina)
  • aluminium hydroxide for chemical applications (chemical grade alumina)
  • liquids from the production of filter aids
  • process liquids from the chemical, food, pharmaceutical and life science industry


Lab and pilot tests guarantee a reliable scale-up and sizing of the production plant.
