Sedimentation is the process of settling or deposition of suspended particles in water or wastewater.

• It is a physical water treatment process.

• It involves the use of gravity to separate solid particles from water.

• Sedimentation tanks are used in water treatment plants to remove suspended solids.

• It is also used in wastewater treatment to remove settleable solids before further treatment.

• The settled solids are called sludge and are removed from the bottom of the tank.

• Sedimentatio...read more

Flock is a process of adding chemicals to wastewater to create clusters of particles that can be easily removed.

• Flock is used in wastewater treatment to remove suspended solids and other impurities.

• Chemicals like alum or ferric chloride are added to wastewater to create flocs.

• Flocs are clusters of particles that can be easily removed through sedimentation or filtration.

• Flock is an important step in the wastewater treatment process to ensure clean water is returned to the envi...read more
