How to Understand Particle Size and Distribution for

How to Understand Particle Size and Distribution for Cleaner Air Particle size is an important factor in air pollution and allergies. We might simply think of airborne particles as a bunch of tiny molecules in the atmosphere. And while this wouldn't be inaccurate, it wouldn't tell the entire story. Indoor air pollution comes in many shapes and sizes. When you get down to the microscopic level

Understanding and Interpreting Particle Size

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.

The Effect of Particle Size Distribution on the Design

The particle size distribution can have a significant impact on the sediment removal performance of s that use settling as the primary form of treatment. The design of s without prior knowledge of the size and density of particles in runoff specific to site conditions could be under- or over-sized.

Monitoring of Representative Particle Size

In terms of TSS control, the particle size distribution of sediment in the runoff controls the amount of sediment (based on Stokes' Law) that may be removed through settling in a typical . For best treatment of TSS, the flow depth in vegetated s during the design storm should be limited to the height of the vegetation.

Particle Size . Suspended sediment particle size distribution (PSD) characterizes the particle size fractions of a given sediment, and is an important evaluation tool as size fractions will vary from site to site based on land use. It is also known that different pollutants will adsorb to different size fractions.
