Water Filtration Vocabulary 24 Runoff – is precipitation that flows over land into streams and rivers. This water later enters oceans. Filtration – process of passing water through a series of screens that allow water through but not large particles Aeration – The water is mixed to liberate dissolved gases and to suspended particles in water column. Coagulation – The process by which particles in a liquid clump together Sedimentation – The water left undisturbed to allow the heavy clumps of particles and coagulants to settle out Disinfection – The water is treated to destroy any remaining disease causing pathogens Potable Water – drinkable water Safe water: water that will not harm you if you come in contact with it.
