Supply of polishing filtration system for Ford wastewater treatment plant
Company : Ford Motors
Location : UK
Year : 2001
Description : Supply of polishing filtration system to Ford’s wastewater treatment plant
Goal : Reduce COD, residual oil and particulate matter
Recycling the polished effluent back to the plant as washwater
Save water and energy costs
Capacity : 500 m3/day
Water Source : Ford industrial effluent
The Problems :
- Existing quartz-sand media filtration system clogged frequently.
- The effluent contaminated the nearby water sources.
- Values of COD, residual oil and particulate matter were above permitted limits for dumping into water source.
- Recycling the polished effluent back to the plant as washwater.
- Save water and energy costs.
Technical Solution :
The following processes were carried out :
- Trials were carried out in a site pilot plant comparing AFM® to quartz sand.
- Full scale filtration system was revamped accordingly with the following processes:
- AFM® – Catalytic Media filtration with coagulation.
- Final disinfection using Sodium Hypo-Chlorine.
Residual Oil (PPM)
Water saving (%)
Electricity saving (%)
- Following AFM® performance with the effluent polishing plant, quartz sand was replaced with AFM® at the process water inlet filtration system.
- Three rapid gravity filters, each requiring 20 tons of quartz sand, were replaced with 18 tons of AFM® each.
- Following the successful implementation of Dryden Aqua’s AFM® in its Essex plant, Ford Motors had decided to implement the same solution in its Paint Shop in Valencia, Spain.
