ABSTRACT:
The solid content and liquid content in a solid-liquid substance can be separated continuously at a high solid-liquid separation ratio by: causing a looped filter cloth member to travel, the filter cloth member being wound at least once around a wringing roller, and having a twisted portion at which the filter cloth member is twisted at least once and wound around the wringing roller; inducing a primary rotary motion of the wringing roller in a direction in which the filter cloth member travels; inducing secondary rotary motion of the wringing roller in a direction in which the filter cloth member is twisted upstream with respect to the wringing roller; and supplying a solid-liquid substance to an upstream portion of the filter cloth member with respect to the wringing roller.
