  • Patent number: 10094099
    Abstract: A dual action retractable screen includes a first screen portion with a first screen portion perforated surface connected to the hinge mount via a horizontal hinge, which allows the first screen portion to rotate within a substantially horizontal plane. The screen also has a second screen portion with a second screen portion perforated surface and a latch pin. A vertical hinge connects the first screen portion to the second screen portion and allows the second screen portion to rotate within a substantially vertical plane. The screen also includes a latch mount that connects to the curb inlet and has a latch saddle that receives the latch pin. The screen operates in two modes: (1) a closed mode where the latch pin is disposed of in the latch saddle, inhibiting rotation about the horizontal hinge; and (2) an open mode where the latch pin is dislodged from the latch saddle, permitting rotation about the horizontal hinge and about the vertical hinge.

  • Patent number: 10087586
    Abstract: A system and method for treating liquid runoff from bridge decks or other types of roadways are provided. The system includes vertical scuppers positioned at low points along a length of a bridge deck. Each scupper has a removable tube fitted inside the scupper with a filtration media for treating liquid runoff such as stormwater. During rainfall events, liquid runoff gravity flows downward through the tubes and the filtration media inside the tubes so that the liquid is treated before being discharged to the environment. The tubes can be removed to periodically replace the filtration media.

  • Patent number: 10052570
    Abstract: A settling basin insert for controlling fluid flow into a settling basin has a first and second side wall in opposition, and a top surface extending between the first and second side walls, defining a sump extending from head to end. Fluid apertures extend through the top surface to permit fluid to communicate with the sump and an access aperture in the top surface permits a vacuum hose to pass into the sump. The first side wall is taller than the second side wall, and the first and second side walls each define a guide wall extending above the top surface. The second side wall is configured to be adjacent the settling basin. The first and second side walls direct inflowing fluid along the settling basin insert and through the fluid apertures in the top surface, decelerating the fluid for settling of sediment in the settling basin insert.

  • Patent number: 10035716
    Abstract: An immiscible liquid separator for maintaining a desired liquid relationship between an oil spillover and a water spillover irrespective of a tilt angle of the separator. The use of the separator is thus well adapted for use on ships and the like. The separator includes a cylindrical weir having an open top over which separated water spills when waste liquid is drained into the separator. The separator also includes a cylindrical oil stack having an open top over which separated oil spills when waste liquid is drained into the separator. The cylindrical oil stack is located within the cylindrical water weir, thus allowing the separator to function as desired independent of the angle of tilt of the separator.

  • Patent number: 10029190
    Abstract: An oil-water separator for separating mixed density fluids, such as oil and water, oily sediment laden water and the like, as well as portable, in-tank and towable and anchorable boom containment systems kits and methods employing the same. The oil-water separator employs at least two oil-separation chambers operating in opposing but synergistic separation modes in parallel. The oil-separation chambers alternate distribution of a single mixed fluid density stream between the chambers using a partial vacuum source to draw the stream into one chamber, while concurrently stopping inflow of the stream into another chamber by removing the vacuum source. The apparatus allows each chamber to switch back and forth between (a) actively separating and removing less dense fluid (e.g., oil) when the partial vacuum is applied, and (b) passively separating the less dense fluid (e.g., oil) and removing the more dense fluid (e.g., water) when the partial vacuum source is removed.

  • Patent number: 9994467
    Abstract: The invention discloses an unpowered water purification system for a riverfront landscape constructed wetland, comprising a riparian wetland constructed along a lake-land ecotone of a river, lake-pond. The riparian wetland comprises a plurality of alternatively arranged wetland islands and watercourses formed between them. The bottom surface of the riparian wetland is lower than the normal water level of the river, lake-pond, and the upper surface of the wetlands is flush with the normal water level of the river, lake-pond. Plants are planted on the wetlands. A revetment is constructed between the riparian wetland and the river, lake-pond, and its upper surface is between the bottom surface of the riparian wetland and the upper surface of the wetlands. The invention achieves good purification and landscape effects. The purification system has some advantages such as good landscape effects, simple management without energy and power consumption, and thus is durable and stable.
