What is a Simple filtration device?

Filtration devices allow liquids containing pollutants to pass through perforated filter media such as paper, cloth, wire mesh, glass cotton, sand, and synthetic fibers.
It is a device that separates particles of individuals larger than the pores and cleans the liquid. Physical forces such as gravity, pressurization, vacuum, and centrifugal force may be used to facilitate filtration, but the most economical and convenient method is coagulation. It's a simple way to flush the wastewater through a filter and separate it into solids and liquids.
