There is provided a material treatment apparatus. The material treatment apparatus includes a first compartment. The first compartment includes an inlet for receiving supply of slurry material, and a first material conduction space for conducting flow of the supplied slurry material in a downwardly direction. A second compartment is also provided including a second material conduction space for receiving a first intermediate material of the supplied slurry material and conducting the first intermediate material in an upwardly direction. A baffle is provided for interfering with conducting of the supplied slurry material from the first material conduction space to the second material conduction space. A turbulent flow mitigation device is disposed within the first compartment and configured to, upon interaction with the supplied slurry material, to effect adjustment to the flow characteristics of the supplied slurry material to generate a downwardly flowing flow characteristic-adjusted slurry material, wherein the flow characteristics of the supplied slurry material are transformed from turbulent flow to laminar flow. The turbulent flow mitigation device is disposed, relative to the baffle, such that the baffle directs the downwardly flowing flow characteristic-adjusted slurry material to a space below the first baffle. The first material conducting space is fluidly coupled, below the baffle, to the second material conduction space, such that the first intermediate material fraction of the downwardly flowing flow characteristic-adjusted slurry material is conducted to the second material conduction space from below the baffle. A collection region is disposed below the first and second compartments for collecting a separated solids-comprising fraction that has separated, by gravity settling, from the supplied slurry material.

A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

A method for static mixing in a waste water settling tank to increase recovery of entrained solids and solvated materials, the method comprising delivering an influent stream at a substantially constant flow rate to a settling tank; discharging a first portion of said influent stream toward a fluid deflector and a second portion of the influent stream into a fluid containment assembly to distribute the influent into contact with previously introduced waste water to create mixing zones and cause coalescence of the entrained solids.

A system and method for static mixing in a waste water settling tank to increase recovery of first entrained solids and solvated materials, comprising a settling tank having a recirculation ring and a hopper bottom defining a sludge hopper having a flat bottom portion, a fluid containment assembly, and a fluid deflector assembly with an optional fluid dispersion assembly. The system further comprises an inlet pipe for introduction of waste water containing second entrained solids and solvated materials into the settling tank and a discharge outlet in proximity to the underside of the fluid deflector assembly with nozzle facing downward. Influent waste water is directed both downward into the fluid containment assembly and upward into the center of the fluid deflector assembly and an optional fluid dispersion assembly to distribute the influent into contact with previously introduced waste water to cause coalescence of the first and second entrained solids.

A waste oil handling apparatus features a tank with draining compartments for receiving waste oil containers in inverted and elevated positions above the tank floor. Multiple drain ports communicate with the tank interior at different elevations relative to the floor for draining accumulated contents of varying density that have gravitationally separated into distinct layers at those elevations. The ports feature adjustable fittings for adjusting the levels from which the layered contents are drawn through the ports from the tank interior. The tank has a large cleanout access by which personnel can access the tank interior for thorough cleanout. The compartments are organized into one or more troughs, each having a pivotal lid thereon. Lift brackets under the floor enable lifted transport of the tank by pallet jack or forklift.

Embodiments disclosed herein relate to an apparatus for refining a liquid stream which includes a liquid carrier with a heavier waste and a lighter waste. The apparatus includes a first flow chamber, a second flow chamber, and plates. The first flow chamber is a cone structure and directs the liquid stream downwards in a first direction at a first velocity. The first velocity is greater than a settling velocity of a heavier waste in the liquid carrier. The second flow chamber directs the liquid carrier upwards in a second direction at a second velocity less than the settling velocity. The plates are in the second flow chamber and at a transition between the first and second flow chambers. The plates have an inclined geometry to cause laminar flow in the liquid stream to separate the heavier waste to a lower collection chamber and lighter waste to an upper collection reservoir.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize clearance space within assembly to facilitate cleaning and increase storage capacity of trash, debris, and sediment.

Embodiments disclosed herein relate to an apparatus for refining a liquid stream. The apparatus includes a first flow chamber, an inclined plate region, and a second flow chamber. The first flow chamber forms a first portion of an hourglass double cone structure and directs the liquid stream in a first direction at a first velocity. The inclined plate region includes inclined plates radiating outward from the hourglass double cone structure in a helical pattern. The inclined plate region directs the liquid carrier in a second direction opposite the first direction at a second velocity less than the first velocity forming a laminar flow condition in the liquid stream to separate heavy waste and light waste from the liquid stream. The second flow chamber forms a second portion of the hourglass double cone structure and directs the liquid stream to a liquid stream outlet.
