As there is no pressure inside this tank, they were also known as'gravity filters '.

3.
First of all, more condensate is removed, then a Coalescing filter acts as a gravity filter and finally an adsorber filled with activated carbon removes some hydrocarbons.
4.
These work on the same principle as rapid gravity filters, differing in that the filter medium is enclosed in a steel vessel and the water is forced through it under pressure.
5.
The "'rapid sand filter "'or "'rapid gravity filter "'is a type of filter used in water purification and is commonly used in municipal drinking water facilities as part of a multiple-stage treatment system.
