Clarification of liquids or the bulk removal of solids from wastewater is used in conjunction with a settlement tank. In a clarifier tank, coagulation and flocculation reagents may be added to the liquid to be clarified. The reagents cause the suspended particles to clump together. These form a sludge, which can be removed from the tank leaving a clarified solution. The Clarification Process Clarifiers are settling tanks used in wastewater treatment, dirty water (contaminated liquid) enters the clarifier tank from the top via a central pipe. As the water speed slows, suspended solids from the liquid sink to the base of the cone. The clean water rises to the top of the tank and flows over launder rings into an outer ‘liner’ from where it is piped away. Lighter particles that float on the liquid are called scum and are held back by the saw tooth launder around the top of the tank. Solid particles which sick to the bottom of the tank concentrate over time and these larger denser particles can be flush down a PN16 drain flange at the base of the cone. The sludge, settled solids and concentrated impurities discharged can be taken away for further treatment.
