PROBLEM TO BE SOLVED: To provide an eco-friendly solid-liquid separation system indirectly suppressing the generation of CO<SB>2</SB>. SOLUTION: The eco-friendly solid-liquid separation system 100 includes: a crude liquid tank 1 into which a coolant liquid used in a manufacturing line 5 is recovered; a centrifugal separator 2 into which the crude liquid is fed from a first electric powered pump P1 via a feed pipe 21; a membrane filtering device 3 into which separated liquid, separated by the centrifugal separator 2, is fed; a filtrated liquid tank 4 in which filtrated liquid separated by the membrane filtering device 3 is stored; a second electric powered pump P2 feeding the filtrated liquid in the filtrated liquid tank 4 to the manufacturing line 5; a third electric powered pump P3 feeding the used liquid of the coolant liquid from the manufacturing line 5 to the crude liquid tank 1; a concentrated liquid tank 6 into which concentrated liquid separated by the membrane filtering device 3 is recovered via a recovery passage 25; and a fourth electric powered pump P4 equipped to the concentrated liquid tank 6. A feed pipe 30 is arranged between a valve 7 equipped in the feed pipe 21 and the fourth electric powered pump P4, so as to feed the concentrated liquid in the concentrated liquid tank 6 to the centrifugal separator 2.
