Legionella & Water Treatment

Coagulation and Flocculation

The raw water is processed with substances such as aluminum sulphate and sometimes with larger molecules called polymers that cause tiny molecules of dirt to stick to each other in a process called coagulation. Coagulation forces the smaller molecules to form into clumps which in turn stick to each other to form larger clumps called flocs. This process is known as flocculation. Because the molecules become enlarged, they become heavier which helps with the next stage of the process when flocs pass through to the sediment tanks.

Sedimentation

Following the coagulation and flocculation process, water is processed into sedimentation tanks. Inside these tanks, water is slowly moved which, along with gravity, causes flocs (coagulated particles) to move to the bottom of the tanks and settle, where they form a sludge substance that is then processed to separate storage lagoons.

Sedimentation enhances the water treatment process by removing any particulates that might remain in the water. Essentially, this process removes the larger contaminants residing in the water before it is ready for filtration.

Filtration

Once flocs have been removed during the sedimentation process, water can then be passed through the filters. Blast furnace slag is used as the filtering medium during a percolation process but other materials such as gravel and anthracite are common. Slag is the byproduct of metal smelting, usually iron into steel and can contain metal oxides, silicon dioxide, sulfides and other metals
