Clarified water
|
| This circular structure is the primary clarifier at Siloam Springs Wastewater Treatment Plant in Siloam Springs, Arkansas. |
Clarification takes place during the pre-treatment of wastewater. Water that has been treated through a clarification process is referred to as clarified water. The process removes solid particles and other solid substances from the water or waste water.
Water clarification systems can be end-to-end or circular (where the water flow moves from the centre out towards the edges of the tank). It is sometimes a multi-step process that first uses the settling action brought on by gravity (sometimes aided by other substances) to separate out grease and other types of floating matter. The next step is to use a clarifier or skimmer to remove the scum from the surface of the water.
