AWWA Coagulation and FlocculationFinely divided solids, such as bacteria and fine clay particles, that will stay suspended in
water for long periods of time. – answer no settleable solids
A physical characteristic of water making the water appear cloudy. The condition is
caused by the presence of suspended matter. - answer turbidity
A term that describes the treatment process used by most US surface water systems,
consisting of the steps of coagulation, flocculation, sedimentation, and filtration. -
answer conventional treatment
The water treatment process that causes very small suspended particles to attract one
another and form larger particles. This is accomplished by the addition of a chemical,
called a coagulant, that neutralizes the electrostatic charges on the particles that cause
them to repel each other. - answer coagulation
The water treatment process, following coagulation, that uses gentle stirring to bring
suspended particles together so that they will form larger, more settleable clumps called
floc. - answerflocculation
Collections of smaller particles (such as silt, organic matter, and microorganisms) that
have come together (agglomerated) into larger, more settleable particles as a result of
the coagulation-flocculation process. - answerfloc
A solid organic and inorganic particle that is held in suspension by the action of flowing
water. - answersuspended solid
A denser and heavier suspended solid that will settle unaided to the bottom of a
sedimentation basin within 4 hours. - answersettleable solid
Finely divided solid that will not settle out of water for very long periods of time unless
the coagulation- flocculation process is used. - answercolloidal solid
Any material that is dissolved in water and can be recovered by evaporating the water
after filtering the suspended material, - answerdissolved solid
The accumulated solids separated from water during treatment. - answersludge
A coagulant aid used to form a denser, stronger floc. - answeractivated silica
