Water Treatment Plants

What chemical is added to the inlet of the water plant?

• Flocculation
• Chlorine
• Coagulants
• Aluminum Solfate

Flocculation Basins....

• hold water to form Flocs
• allow flocs to create Coagulations
• allow Coagulants and water to mix to form Flocs

Sedimentation will settle

• as sludge at the bottom of the tank
• as sludge at the top of the tank
• as chemical waste

As bubbles are injected in the tanks, they

• create a chemical reaction that form flocs
• cause sedimentation
• float up taking floc particles with them

In dissolved air floatation tanks, clean water is taken from the

• Top
• Bottom
• Middle
