PRELIMINARY TREATMENT
The first step in treating the wastewater entering the treatment plant is to remove RAGS (things like paper towels) and GRIT (sand and gravel).
This is a two step process. First, the rags and other large material are removed using BAR SCREENS. The Bar Screens have narrow slits that capture this material, while letting the wastewater pass through to the next stage of treatment. The debris is removed in this stage of treatment so it will not interfere with the other stages further downstream.
The CYCLONE DEGRITTERS remove sand and grit from the wastewater. This prevents wear and tear on pumps and piping within the rest of the treatment facility.
