Filtration is the process of passing a substance through a filter media to collect specific particles.
While there are countless applications and techniques that can be used to filter particles, there are ultimately two types of filtration: liquid and gas.
Gas filtration is the act of passing gas or vapor through a fine mesh filter to remove contaminant particles.
Liquid filtration is the act of removing contaminant particles from a liquid to either refine the liquid or collect a filter cake.
