About Water Treatment in Peel
Lorne Park Water Treatment
The Region’s second facility - the Lorne Park Water Treatment Plant - has state of the art technology that uses two different processes to treat 500 million litres of water per day.
These steps include:
- Chlorination: Controls zebra mussels and provides primary disinfection.
- Conventional Treatment
- Coagulation: A chemical addition to help mix the organics and solids in the raw water.
- Flocculation: The configuration of the flocc tanks provide energy to disperse the coagulant and encourage flocc (solids) to form.
- Sedimentation: The speed of the water slows down enough in this stage to allow any flocc that has formed in the previous stage to settle out.
- Dual media filtration: Water is filtered by gravity through the filter to produce finished (clean) water.
- Membrane, UV and Granular Activated Carbon Contractor (GACC) Treatment
- Membrane Filtration: During this stage, small particles and microorganisms are removed through membrane fibres by ultra filtration.
- Ultraviolet (UV) Light: Filtered water passes through these units, which disinfect water by inactivating microorganisms. Along with hydrogen peroxide, these UV units are used for taste and odour control.
- GACC: Water is filtered by gravity through the carbon bed for peroxide quenching and additional taste and odour control.
- Chlorination and Fluoridation: Chlorine and fluoride are added at concentrations that comply with the Ontario drinking water legislation.
