Abstract: A waste fluid treatment apparatus includes a sedimentation tank that stores the processing waste fluid with the processing debris contained therein, an inflow port provided on the sedimentation tank for introduction of the processing waste fluid into the sedimentation tank, an acidification unit configured to acidify the processing waste fluid to be introduced from the inflow port into the sedimentation tank, whereby the processing debris is allowed to settle at a higher rate compared with a rate at which the processing debris would settle if the processing waste water is neutral, and an outflow port provided on the sedimentation tank for discharge of acidic supernatant that is obtained by allowing the processing debris in the processing waste fluid to settle in the sedimentation tank from the sedimentation tank.

Abstract: A sedimenting assembly for sedimenting debris contained in a processed waste liquid in a sedimentation tank includes a plurality of partition plates extending vertically across a direction in which the processed waste liquid flows and disposed at spaced intervals in the direction, thereby defining a zigzag channel through which the processed waste liquid flows horizontally. The zigzag channel ensures a time during which to sediment the debris against a time during which the processed waste liquid flows through the zigzag channel, allowing the debris to settle reliably.

Abstract: A processing apparatus including an expansible and contractable bellows unit mounted on a workpiece holding unit for covering an area of movement of the workpiece holding unit in a feeding direction and a guide unit for guiding the expansion and contraction of the bellows unit in the feeding direction. The guide unit has an opening for allowing the movement of the workpiece holding unit in the feeding direction and a gutter extending in the feeding direction adjacent to the opening. The bellows unit has a bellows member having one end connected to the workpiece holding unit and the other end connected to the guide unit. The processing apparatus further includes a floating unit for floating the bellows member along the gutter of the guide unit in a noncontact manner.
