Satisfactory results can be obtained by allowing the sediment water to flow in the settling water discharge tank (1) for 30 minutes or more. In other words, if the lubricating oil in the settling water discharge tank (1) is sent out to the lubricating oil storage tank (B) over 30 minutes or more by the pump (P 1 ) of the transfer section (3), Lubricating oil (O) from which (W) has been sufficiently removed can be obtained.
