At Drinking Water Treatment Plants, the raw water undergoes a series of processes designed to remove the substances that could be harmful for human consumption. At conventional plants, these processes consist primarily of:
- Regulation. Set of mechanisms that regulate the inflow of water to the plant, adapting it to the plant’s treatment capacity.
- Flocculation. Process by which chemical reagents are used to create flocs that move slowly through the decanters and are deposited at the bottom to be removed and eliminated properly afterwards.
- Filtration. This is normally done by moving the decanted water through a sand bed, retaining the particles that were not separated in the flocculation process.
- Disinfection. Chlorination process to guarantee a residual chlorine load throughout the distribution pipes.
