|Description:||Supply of polishing filtration system to Ford’s wastewater treatment plant|
|Water Source:||Ford industrial effluent|
- 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.
|Parameter||Existing Values||Required Value|
|Turbidity (NTU)||50||< 5|
|COD (PPM)||750||< 50|
|TSS (PPM)||150||< 5|
|Residual Oil (PPM)||15||< 1|
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.
|Parameter||Required Value||Before treatment||After treatment|
|Residual Oil (PPM)||1||15||1|
|Water saving (%)||Minimize||0||74%|
|Electricity saving (%)||Minimize||0||21%|
- 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.
