Question

To physically remove these tiny particles, facilities may use a huge system of filters known as ________?

1) Strainers
2) Sieves
3) Screens
4) All of the above

Answer 1

Facilities use membrane filters to physically remove tiny particles, such as bacteria, from fluids. The filters have an effective pore size of 0.2 µm and are commonly used in laboratories for heat-sensitive solutions and culture media.

Step-by-step explanation:

To physically remove these tiny particles, facilities may use a huge system of filters known as membrane filters. Membrane filters function similarly to HEPA filters, with an effective pore size of 0.2 µm, which is smaller than the average size of a bacterium. These filters are commonly used in laboratories to remove bacteria from various heat-sensitive solutions and culture media.
