What is a Filter Press and How Does it Work?

What is a Filter Press? A filter press is a piece of equipment used in liquid/solid separation Specifically, the filter press separates the liquids and solids using pressure filtration, wherein a slurry is pumped into the filter press and is dewatered under pressure Basically, each filter press is designed based on the volume and type of.
