The purpose of this lab was to measure the turbidity of raw river water by performing a jar test. Turbidity is the measure of the presence of suspended solid material in the water. In order to measure these suspended solids the particles must first be flocculated, or combined into groups, thereby increasing the effective diameter. This is done through a process called coagulation.
Coagulation is a chemical technique directed toward the destabilization of colloidal particles.
The above picture shows the jar test apparatus that was used in the lab to induce flocculation of the suspended particles in the raw river water sample.
