A method and apparatus for collecting agricultural manure in a confined animal feeding operation includes a separator which receives heavy manure removing particulate from suspension to produce light manure. Heavy manure is collected to a volume of heavy manure sufficient to substantially fill the first tank. Within the first tank, particulate migrates, due to the influence of gravity to form a layer containing manure comprising a lesser density of particulate than is present in the volume of heavy manure. Additional heavy manure buoys the layer such that the upper surface exceeds a height of a weir. The weir is situated in a channel communicating between the first tank and a second tank configured to receive light manure from the separator.

A system for reloading a container with proppant. The system includes a transloader having a conveyer belt and a discharge device. The system includes a reloading system comprising a bulk material storage bin having a proppant receiving area, a funnel having an expandable loading tube, and a gate for controlling flow of the proppant from the funnel into the container. The system comprises a reloader comprising a loading bay having a load cell and the container disposed on the load cell.

A container for storing and transporting material includes a container body having a bottom wall and a pair of parallel spaced side walls connected with opposite edges of the bottom wall to define a chamber having first and second open ends. A pair of ramp walls are connected with the container body adjacent the first and second open ends, respectively. Each ramp wall includes at least one pivot assembly, which provides pivotal movement of the ramp wall between closed and open positions, respectively. Preferably, the pivot assembly includes at least one pivot shaft extending through one end of the ramp wall and at least one counterbalancing helical torsion spring cooperating with the pivot shaft to bias the ramp wall during movement between closed and open positions.

A sulfur storage tank includes a bottom plate, an outer wall, and a cleanout door. The outer wall surrounds and is coupled to the bottom plate. The cleanout door is installed on the outer wall. The cleanout door includes an edge and a drain nozzle. The edge abuts the bottom plate. The drain nozzle is installed on the cleanout door. The drain nozzle defines a centerline offset from the edge. The drain nozzle is configured to gravity drain fluid from the sulfur storage tank.

An intermediate bulk container (IBC) system comprising a base and walls, and having an interior space. The system comprises a drain in the base or in a wall, a liner bag having a liner bag drain couplable to the drain in the base or in a wall, and a door coupled to the wall by a hinge and shaped to cover an opening in the wall. The opening extends from a top of the wall. The hinge is coupled to the door to allow the door to rotate into the interior space. A stop prevents the door from rotating beyond the wall. The system may be used by rotating the door into the interior space to expose the opening, reaching through the opening and operatively coupling the liner bag drain at the drain in the base or in a wall, and rotating the door to cover the opening.

A liner (L) has a liner body (11) with a front wall (12), rear wall (16), bottom wall (13), a top wall (14). The top wall also includes a tubular excess liner material or chute (19) located close to the rear wall and which includes a filling fitment (20) with a fitment cap (21). The liner also has a cylindrical, hose content inlet/outlet port or bottom fitment (23). The liner may include a gap-filler or filler strip (90) of foam material extending outwardly from a position closely adjacent the outlet fitment. The filler strip is mounted to the front wall and/or top wall. The filler strip may taper so that at least a majority of the strip's longitudinal length or height so as to increase in its lateral width as it approaches the outlet fitment, thereby increasing the material volume of strip material.
