ABSTRACT:
A liquid filtering and supply system according to the present invention comprises, a main line to connect a liquid introducing part to a liquid supplying part, a filter disposed in said main line to filter said liquid, a first pressure detector disposed in said main line at an upstream side of said filter to detect a pressure of said liquid before said liquid is introduced to said filter, a second pressure detector disposed in said main line at a downstream side of said filter to detect a pressure of said liquid after said liquid passed out of said filter, a first circulating line for returning a liquid in said main line to the liquid introducing part, a pressure difference computing element to determine a pressure difference between the first pressure detector and said second pressure detector, a control valve disposed in the first circulating line, and a controlling part to adjust an opening of said control valve, based on a signal of the pressure difference transmitted from the pressure difference computing element.
