Abstract:
A mobile water re-use system can include a chemical treatment apparatus, at least one weir tank in fluid communication with the chemical treatment apparatus, and two or more settling tanks in fluid communication with each other and at least one of the settling tanks in fluid communication with the weir tank. The weir tank can have a first end, a second end, an internal chamber, and a plurality of baffles that induce turbulent flow of fluid through the internal chamber. The settling tanks can provide, promote, facilitate, result in, and/or induce laminar flow of fluid through at least a portion of the internal chamber. Weir tanks, settling tanks, and method of treating flowback and produced water are also described.
Abstract:
The present invention relates to a removal device for removing dirt particles and/or gas bubbles from a liquid in a liquid conduit system, the removal device comprising: -a housing having an entry and an exit, the housing defining an inner space within the housing, -a main inner channel constructed to guide a main flow through the inner space from the entry to the exit, -at least one branch flow channel, which branches off from the main inner channel at a branch location, the branch flow channel being configured to - in use - branch off a relatively small portion from a main flow, -at least one quiet zone in the inner space, wherein in use the at least one branch flow channel discharges into the at least one quiet zone, wherein the dimensions of the quiet zone is chosen in such a way that in use, a velocity of the liquid in the at least one quiet zone is lower than in the main inner channel and low enough to allow: - dirt particles to settle and/or -gas bubbles to form and rise in the at least one quiet zone, -at least one return flow channel for a return flow from the at least one quiet zone back to the main inner channel, wherein the return flow channel merges with the main inner channel at a merge point.
Abstract:
A separator (2) for separating solids, such as grit, from an influent, such as water, the tray assembly (4) comprising a plurality of nested tray units (14) which are spaced apart from one another along a vertical separator axis (16). Each tray unit (14) comprises a substantially conical tray (18), an aperture (20) in the apex of the tray (18), and a means for restricting flow through the respective aperture (20), such as a baffle (22) disposed at or adjacent the aperture (20). In use, grit is separated from water circulating among the trays (18) and falls through successive apertures (20) in each of the trays to exit through the bottom of the tray assembly (4). The baffles (22) restrict upward flow through the apertures (20) in the trays (18) thereby reducing agitation of the grit.
Abstract:
The invention relates to an integrated waste water purification plant, wherein the clarifier and mechanical units are arranged in a common complex structure (1), the crane is a swing crane (4) having a fixed hollow central column (14) coaxial with the vertical geometrical axis of the complex structure (1), and further being provided with a support (43) having wheels (431) running on the structure and cable-strands (142) for the electrical equipments of the complex structure (1) accommodated in, and a control cabinet (141) of the whole system mounted on said central column (14). The method for preparing the plant comprises the steps of excavating a circular ground pit first, and, preparing a concrete base in the centre thereof, with anchor bolts for holding a column base, erecting an assembled column/control-cabinet/cable-strand unit on said base, arranging the electrical and hydraulic lines on the concrete base and covering them with a base body of reinforced concrete, mounting a swing crane track with a support provided with wheels on the column, and providing the support with temporary leg extensions so that the wheels at their ends run on the base body, and building the walls of the complex structure, removing the leg extensions of the support, and preparing the biological reactor, the clarifier and mechanical units inside the walls by means of the swing crane.

Abstract:
A variety of improved hydrocyclones (100) for filtering water and other fluids are disclosed. The hydrocyclones (100) generally include a tank having an internal chamber (110) with a chamber wall (105) and a cross-flow stepped filter (120) positioned within the internal chamber (110). The hydrocyclones (100) may be operated such that a vortex of flowing fluid is formed between the chamber wall (105) and the cross-flow stepped filter (120), the filter (120) being located in the center of the vortex. In some preferred embodiments, the cross-flow stepped filter (120) has openings that are arranged as slots that extend substantially vertically so they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex. In yet another aspect of the invention, a circulating cleaning assembly is provided. In yet another aspect of the invention, an intake structure is provided.

Abstract:
A separator that utilizes an arcuate inlet manifold (14) and an arcuate baffle (16) to increase the rate of separation for a mix of materials having different specific gravities. The separator includes an arcuate baffle (16) that defines a separation chamber (32) and an arcuate pipe (58) through which a mixture of materials having specific gravities is carried into the chamber (32). The mixture is discharged into the separation chamber (32) against the baffle (16) through a series of openings (60) disposed along the perimeter of the pipe (58). The baffle (16), pipe (58) and openings (60) are configured relative to one another such that mixture is discharged against the baffle (16) at an oblique angle. In preferred versions of the invention, mixture is discharged slanting up, slanting to the side or slanting up and to the side against the baffle (16) at an angle of 18 DEG to 24 DEG (most preferably at about 22 DEG ).
