If the pores of the filter are smaller than the particulate, they cannot pass through and are trapped in the filter. The filter might not have small enough pores to filter everything out.
It does because filtering traps have very tiny holes. If the particles are not dissolved than the filtering trap will catch them.
freezing point
Filter paper is more dense than usual paper so it can be used to trap particles in a filter. Tracing paper is thin and seethrough so it is easier to see what you are tracing.
Electrolytes trap suspended particles by causing them to clump together and fall to the bottom of the tank as sediment. These clumps are called floc, and the process is called flocculation.
toilets have a built in water trap And they should be properly vented to prevent trap seal loss
It does because filtering traps have very tiny holes. If the particles are not dissolved than the filtering trap will catch them.
An anti-siphon trap is used to prevent reverse flow
To trap inhaled particles and move them out of the airways.
The particles are too fine for the sand to trap, sand filters trap particles down to 25 microns. Dead algae can be a lot finer than that. The only filter that can trap real fine particles down to 3 microns are d.e. filters.
dust
cylia cells
It has small dense hairs lining it that trap small debris, thus filtering the air.
S Traps is garbage as it can self syphon P traps are legal
They trap tiny particles of food as they drift by.
Freezing
Its called the cilia.
Turbinates of the nose.
