  • The existing sand filter system is often clogged.
  • Wastewater in the factory contaminates nearby water sources.
  • COD residual oil and particulate matter exceed the permissible limits for dumping into water sources


  • Recycle the polished effluent back to the factory as a rinsing water.
  • Save water and electricity bills

Technical Troubleshooting:

The process of operation is as follows:

  • The experiments were conducted in a local pilot plant comparing AFM® with quartz sand.
  • The full-scale filtration system has been revamped according to the following processes:
  • AFM® – Hardening Catalytic Media Filtration
  • Final disinfection using sodium hypochlorite

Variant Required Value Before-Treatment After-Treatment
Turbidity (NTU) 5 50 1
COD (PPM) 50 750 30
TSS (PPM) 5 150 5
Residual oil (PPM) 1 15 1
Save water (%) Minimize 0 74%
Energy saving (%) Minimize 0 21
  • Due to the efficiency of the AFM® filter, quartz sand is converted to the AFM® glass filter during the water inlet stage.
  • Three gravity filters, each requiring 20 tons of quartz sand, converted to 18 tons of AFM® glass filter media.
  • Following the successful implementation of AFM® in the factory, Essex Ford Motors decided to implement the same solution in a paint shop in Valencia, Spain.
