According to Lenntech, a water treatment solution company, filtration is often used in chemistry with a Büchner funnel and filter paper. Microfiltration is utilized to aid in the processing of sewage. A specially made membrane is used to filter out microorganisms. Recently, nanofiltration has become popular for both filtering groundwater and processing food. This process filters out dissolved solids that would normally pass through most filtration processes.
