Suspended Substances: Nonliving Particles
This lesson is designed to help water system operators understand the characteristics of nonliving suspended particles such as colloidal silica, colloidal organics, silt, clay and sand. When these substances cause problems for an RO unit, the problems generally are fouling and additional indirect consequences of fouling.
Educational Objectives:
- When given a practice exam, be able to correctly identify the terminology associated with nonliving suspended substances (sand, silt, clay, and organics), including their chemical makeup and classification based on particle sizes and composition.
