Introduction:
Before discussing the process of filtration, the definition of some keywords is necessary-
Filtration: The process used to separate solids from liquids (or gases) using a porous medium
(filter) through which only the fluid can pass, leaving behind the solid particles in the filter.
Filtrate: Refers to the resulting liquid (or gas) that passes through the filter during the
filtration process. It can also referred to as the purified or separated substance after filtration.
Precipitate: According to Chemicool (2017), precipitate refers to the solid material that forms
out of a solution during a chemical reaction. It appears as a solid settling at the bottom of a
container or as suspended particles in the solution.
Gravity: Gravity is the natural force of attraction that pulls objects with mass towards each
other. In this case, gravity refers to the force attracting the filtrate through the filter, resulting
in filtration.
, Gravity Filtration: This refers to the method of filtration where gravity is used to draw the
liquid through a filter medium. According to Nichols (2017), gravitation filtration is a simpler
and more commonly used technique for separating solids from liquids and is usually
performed to retain the filtrate.
Suction Filtration: According to Nichols (2023), suction/vacuum filtration is a filtration
technique in a vacuum to pull the liquid through the filter medium, thereby speeding up the
filtration process. This process is used to retain the solid/precipitate.
Filtration, a pivotal separation technique in chemistry, involves the separation of solid
particles from a liquid phase through a porous medium. This process is dependent on the
difference in particle size and solubility, allowing the larger insoluble solid particles, also
known as the precipitate, to be retained by the filter medium while the soluble compound,
known as the filtrate, passes through.
There are two types of filtration methods, gravity, and suction filtration, and each has a
different purpose. Gravity filtration uses the force of gravity to facilitate the passage of the
liquid/filtrate through the filter medium, relying on the pressure differential between the top
and bottom of the filter setup. Conversely, suction filtration introduces an external force,
typically generated by a vacuum pump, to expedite the filtration process by speeding the rate
of liquid flow through the filter.
