Particle Analysis in Environmental Applications
Particle Removal
Task: Profile a conventional drinking water treatment plant in terms of suspended particulates and particle removal effectiveness.
Sample: River water (drinking water treatment plant source), settled water (granular media filter influent), and filter effluent.
Run Conditions: Samples were analyzed at magnification 5x and 14x. Particle diameter and concentration were measured. Particle images were stored. Turbidity and online particle counter readings were recorded.
Analysis: Removal of particles >1µm (raw water vs. filtered water) was found to be 98.07%. Particle counts were found to be consistently 5 to 6 times greater than those recorded by the online particle counters.
