ABSTRACT:
Filtering liquids, such as slurries, oils, coolants, paints, and others, is an inefficient, time consuming process. For example, slurries are commonly filtered with a hand screen. However, a filter pump connected to at least two filters connected series, can be utilized to efficiently filter liquids.
