Abstract:
A separator unit includes a tank defining an internal volume and having an inlet and an outlet. A deck within the tank separates the tank into an upper chamber and a lower chamber. A weir at an upper side of the deck defines an inlet side atop the deck for receiving an influent liquid and an outlet side atop the deck, with a first opening through the deck on the inlet side for delivering liquid down into the lower chamber, and a second opening through the deck on the outlet side for delivering liquid from the lower chamber back up into the upper chamber. The separator includes one or more of an integrated drop pipe assembly with a dispersal manifold, a riser path with a vortex disrupting vane and/or a second opening configuration that is at the perimeter of the deck.

Abstract:
A hydroclone (10) including a tank (12) with a fluid inlet (14), a filtered fluid outlet (16), an effluent outlet (18), a process fluid outlet (20) and a chamber (24) including an inner peripheral wall (22) centered about a central axis (X). The hydroclone further includes: i) a filter assembly (26) located within the chamber (24) which has an outer membrane surface (44) symmetrically located about the central axis (X) and encloses a filtrate chamber (46) that is in fluid communication with the filtered fluid outlet (16), and ii) a cleaning assembly (50) concentrically located and rotatably engaged about the membrane surface (44). A fluid pathway (28) extends from the fluid inlet (14) and defines a vortex region (25) between the inner peripheral wall (22) of the chamber (24) and the membrane surface (44) and is adapted for receiving incoming fluid. An inlet flow shield (58) is concentrically located about the filter assembly (26) and is adapted to block at least a portion of fluid flowing into the chamber (24) from the fluid inlet (14) from impacting the membrane surface (44).
Abstract:
A separator for separating oils from waste water and solids. Waste liquids are drained into a baffle tube of the separator so that the oils rise and the waste water and solids migrate to the bottom of the separator. A collection head having a restriction is located at the bottom of the separator and is adapted for suctioning the waste water and the solids therein and carrying the same to a discharge outlet of the separator. Waste liquids drained into the separator provide the hydraulic force to accelerate the waste water and solids into the collection head. Liquids drained into the separator also provide the hydraulic force that allows the oils to be drained from the top of the separator.
Abstract:
An apparatus and method to separate grease and solids from wastewater before reaching the sewers using a grease trap, wherein said grease trap comprises a detachable residue trap reducing turbulence and including a mesh which efficiently trap solid particles from the water waste in other to make easier the compliance with regulating agencies.
Abstract:
Disclosed is a system for treating waste water. The system may be applied to any application for the treatment of waste water which benefits from an equalized flow into the waste water treatment processes, such as industrial batch discharges, storm water settling and screening, and septic receiving at a waste water treatment plant. The system comprises a single primary settling tank for the processes of grit removal, flow equalization, fine screening and primary clarification. The system further comprises the use of a flow measurement device on the discharge side of the primary settling tank to provide a uniform flow to downstream processes. The system further comprises placement of a fine screen on a discharge mechanism which controls the effluent flow from the primary settling tank.
Abstract:
Separator for removing impurities, especially smaller particles, from rain water. It comprises a first reservoir (2) and a second reservoir (6). The first reservoir (2) performs the function of removing the heaviest portions of the impurities, but is also provided with a lamellar device (4), wherein small drops and impurities of the rain water may be combined to larger impurity aggregates. The second reservoir (6) is divided into a first chamber (6a) and a second chamber (6b), said chambers communicating with each other. A tube (5) provided with perforations (5') is arranged above the lamellar device (4), through which rain water containing impurities is able to flow from the first reservoir (2) and into the first chamber (6a). The first chamber (6a) is provided with a filter (9). In this way, a more efficient purification of rain water than using the known separator is provided.
Abstract:
A system and process are provided for recovering and/or cleaning residual or waste petroleum products such as sludge accumulated within a storage tank or upon process equipment surfaces, or from inorganic materials such as sand or clay, and the like. The system and process include a negatively charged aqueous-based dispersion fluid, which is contacted with the petroleum product under controlled relatively high pressure and high shear conditions for fluidizing hydrocarbon molecules and for preventing such molecules from adherence to process equipment surfaces, or contaminants such as sand or clay. Additional mechanical separation as by subjecting the mixed petroleum product and dispersion fluid slurry to sonic vibration may also be employed. The thus-fluidized slurry of petroleum products, dispersion fluid, and inorganic materials can be separated by conventional techniques, as by setting and/or flotation, for further individual processing and/or re-use.
Abstract:
A separator for separating particles, especially amalgam particles, from effluent liquid obtained from the suction apparatus of a dental office, preferably driven by a common vacuum pump, includes a sedimentary deposit tank for sedimentation of solid particles in the effluent. A surge tank is provided for accommodating effluent overfill and providing its effluent output to the sedimentary deposit tank. A bypass conduit is connected in parallel with the separator and to a vacuum check valve in the vicinity of the separator inlet port for passing air into the separator when the suction apparatus is closed to ambient air, so that whenever the vacuum pump is operating, air is sucked into the separator either through the suction apparatus thence into the separator inlet port or via the vacuum check valve. The surge tank preferably has a liquid level sensor and associated warning device. An auxiliary filtration device may be connected downstream of the sedimentary deposit tank, and both of these units are preferably removably replaceable as modular units. Provision is made for optional auxiliary equipment to improve filtration and to accommodate a positive air pressure source. A full tank drying facility is optionally provided.
