Abstract: Mesh cells (30) for machine-made netting (51) use pairs of mesh bars (35) made from a continuous length of material and meet at a common coupler (34). Such mesh bars (35) have a lay with a common direction throughout the length of material. In a zig-zag pattern used in knitting machine-made netting (31), the longitudinal axis of symmetry (38) of mesh bars (35) turns at each coupler (34). Towing such mesh bars (35) causes water to flow past pairs thereof in two different directions with respect to their common lay. The directions of water flow are neither parallel nor perpendicular to the longitudinal axis of symmetry (38) of the mesh bars (35). As water flows past the mesh bars (35), the cross-sectional shapes of the mesh bars (35) produce a net component of force that is oriented in a direction perpendicular to a combined drag component of force for the mesh bars (35).

Abstract: A method and apparatus for efficiently separating solids from liquid/solid slurries are disclosed. The slurry to be separated is retainably placed within a container having one or more lift paddles secured within its inner cavity. The container is supported for rotation about an axis and has drive means for slowly rotating the container. As the container rotates, the lift paddles lift a portion of the retained slurry, allowing the liquid portion to fall back into the primary slurry pool to be separated, and lifting coarse solids toward the top of the rotation path of the paddles. The separated solids slide by gravity from the lift paddles as they approach the top of their rotation paths and into a collection tray. A filter that rotates with the container filters fine solids from the liquid portion of the slurry and also deposits the fine solids on the collection tray. The filtered liquids can be readily pumped from or recirculated to the separator.

Abstract: A solvent recovery apparatus for recovering low volatility solvent from a washing fluid slop includes a settling system and a filtering system. The settling system includes one or more settling stages and an off-take by which settled, re-usable solvent may be recovered. The filtering system uses a single filter press to filter batches of wastewater, with solids, and batches of solvent sludge, with solids, such that cleaned wastewater filtrate may be discarded, benign removed solids may be dried and sent to landfill, and solvent filtrate may be returned to the input end of the solvent recovery apparatus for re-processing. The solvent recovery apparatus can use a two stage settling system which permits an initial separation of most of the wastewater, and a secondary settling of a solvent rich portion of the slop. The secondary settling can be performed with a system of alternating settling tanks in which one tank is allowed to settle while another is being filled.
