An extrusion system for separating soil entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of soiled water, to allow soil to settle by gravity, and to allow clarified water collection at the top. A diffuser suspended within the tank converts the flow of soiled water into multiple transverse flows to avoid churning the settled soil. A sensor detects the level of settled soil reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated soil from the bottom of the settling tank.

A system for isolating a target molecule from a bioprocess fluid includes a single-use disposable separation device having a plurality of perimeter-bonded layers defining one or more mesofluidic channels of the separation device, wherein each layer includes a biocompatible polymer material, wherein the separation device is configured to separate at least a portion of particles from the bioprocess fluid to generate a substantially clarified bioprocess fluid, and a chromatography system fluidically coupled at the outflow of the separation device in a configuration for further processing the clarified bioprocess fluid.

A liquid treatment unit removes particulate matter and colloids from a liquid, as found in waste water on mines, on construction sites and on heavy industry sites. The liquid treatment unit includes an electrocoagulation unit and a cyclonic separator unit. The liquid to be treated is first subject to electrocoagulation and then fed into the cyclonic separator unit. The cyclonic separator unit guides the electrocoagulated liquid in a circular path downwardly from an outer perimeter to move underneath a skirt and then upwardly and inwardly towards a central outlet located at the top of the cyclonic separator. Floating particles are skimmed from the surface outside of the skirt. In moving to the outlet, the liquid passes through a plurality of nested frusto-conical guide members. An ultrasonic transducer is used to collapse bubbles formed by electrocoagulation, and to clean the electrocoagulation electrodes.

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. In particular, the described hydrodynamic separator is an improvement over other hydrodynamic separators known in the art with the inclusion of one or more down pipes which siphon water from the lower portion of the sump chamber. The inclusion of down pipes allows for an improved control of the velocity of the water flow through the device by distributing flow into more than one path.

A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

A single stage clarifier mixing assembly includes a housing having a circular sidewall and a center axis, a mixing section in the housing, a clarifier section overlying and axially aligned with the mixing section along the center axis within the housing, an inlet delivering an inlet stream to the mixing section and an agitator. The agitator is adapted for mixing the inlet stream in the mixing chamber.

An oil and grit separator system having twin vortex which uses gravity providing a twin vortex effect to remove sediment and oil from contaminated water. The system is designed to control storm water runoff and reduce the annual suspended solids loading of the granulometric particles. The conception and configuration of the system has a double action vortex. It ensures an optimal treatment level in either light or heavy rain and avoids re-suspension of particles. It also removes, separates and stores floating oil without any possible re-suspension of the matter.

A grit removal unit including a cylindrical grit removal chamber above a grit storage chamber, with an opening to the grit storage chamber through the grit removal chamber bottom. At least one layer plate is an inverted truncated cone around the center axis which is spaced from the grit removal chamber vertical wall to allow fluid flow therebetween. Concentric inverted truncated cone lamella plates are supported in the grit removal chamber above the layered plates, with the lamella plates radially spaced from one another relative to the center axis. An influent opening in the grit removal chamber vertical wall below the layered plates allows fluid and grit into the grit removal chamber, and an effluent opening in the grit removal chamber vertical wall above the lamella plates allows fluid to exit the grit removal chamber.

A neutralization/water separation tank for an esterified product including: a neutralization part in which a crude product mixture containing alcohol and an ester compound, a neutralizing agent, and water are put to produce a neutralized mixture; a water separation part which divides the neutralized mixture into a floating layer and an aqueous layer; a first partition wall which extends upward from a bottom surface to provide an upper passage and by which the neutralization part and the water separation part are partitioned; and a second partition wall which extends downward from a ceiling to provide a lower passage, wherein the water separation part includes: a first water separation part into which the neutralized mixture is introduced from the neutralization part through the upper passage; and a second water separation part into which the neutralized mixture is introduced from the first water separation part through the lower passage, wherein the first water separation part and the second water separation part are partitioned by the second partition wall.
