Supply a polished filter system for a Ford wastewater treatment plant
Ford Motors Company – Dagenham, Essex. Supply of Post- polished filtration systems for Ford wastewater treatment plant.
Company name: Ford Motors
Location: UK
Year: 2001
Title: Supply of post-polishing filtration systems to Ford wastewater treatment plants.
Goal: Reduce COD, residual oil and dust. Recycle polished effluent back to the factory as rinsing water, saving water and energy costs.
Capacity: 500 cubic meters/day
Water source for treatment: Ford industrial effluent
Problems:
- 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
Challenge:
- 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
Results:
| 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.
