The Eight Steps Involved in Water ... - LIVESTRONG.COM

In filtration, the water flows through a multilayer medium such as quartz sand, activated carbon or anthracite coal in order to remove up to 99.5 percent of the solid materials remaining in it, whether flocs, microbes or minerals. This step usually is the last one in the process of removing solids from the water.

What Does Charcoal Do In Water Filtration - The Water Filter

Charcoal Filters and Carbon Filters. Charcoal is an extremely porous carbon which forms when millions of micro-pores open between carbon atoms open up after it mixes with oxygen. Charcoal can attract and hold very many contaminants passing through it. People treat charcoal with oxygen to make activated charcoals that are effective at adsorbing odors and colored substances from liquids and gases.

Filters | Radiology Reference Article | Radiopaedia.org

Filters. Filters are metal sheets placed in the x-ray beam between the window and the patient that are used to attenuate the low-energy (soft) x-ray photons from the spectrum. Filtering is the removal of these low energy x-rays from the beam spectrum which would otherwise not contribute to image quality but would add to patient dose and scatter.
