h5. Lamella
Lamella are thin, gill-shaped plates held together. In sedimentation tanks, they are placed near the top of the free surface and are used to help flocs settle to the bottom of the tank.

h5. Flocculation
The process during which particles in water form little clumps by bumping into each other and sticking together with the help of a coagulant (a substance that causes particles to stick to each other). In the pilot plant, flocculation occurs in the flocculation tank.
\\
\\
h5. Floc
A clump of particles stuck together with coagulant. Visible flocs in the pilot plant range in size from that of a pinhead to marble-size. Large flocs look like grayish-brown lumps that you could pick up, but they usually disintegrate upon touch.

h5. Sedimentation
The process by which flocs settle to the bottom of a tank, leaving clear, clean water on top.
