Patent number: 10662637Abstract: The subject disclosure is directed to a liquid purification assembly featuring an inclined cell separator located within a chamber. The separator features a plurality of plates oriented perpendicular between opposing spaced-apart substantially vertical weirs. The plurality of plates are substantially parallel to one another and extend longitudinally within the chamber. The first and second weirs can have a plurality of orifices extending therethrough between their front and rear surfaces. The chamber features an influent chamber, an effluent chamber and a sediment collection area along the bottom of the chamber below the cell separator. A net extending from the top edge of the first weir and over a portion of the cell separator is further provided. The assembly features a hinged baffle suspended below the bottom edge of the second weir.Type: GrantFiled: February 1, 2017Date of Patent: May 26, 2020Assignee: FRESH CREEK TECHNOLOGIES, INC.Inventors: Dennis R.

Patent number: 9695584Abstract: This device serves to improve water quality under gravity flow conditions. The water quality treatment device traps floating debris with replaceable netting, it contains oil spills and settles sediment in self-cleaning settling cells above a collection bunker inside a chamber. The device directs the water below the inclined cells, through the inclined cells, or over the inclined cells, depending on the inflow intensity. All inflowing water enters the net cavity and the net is supported by the inclined cell assembly. The pollutant collection surfaces are overlapping each other and aligned with the water flow direction. A hinged baffle with orifices controls the flow rate through the inclined cells. The netting is replaceable when filled with debris through an access opening in the ceiling of the chamber. The sediment bunker is cleaned through access openings in the ceiling from the chamber inflow side and the exit side.Type: GrantFiled: October 24, 2013Date of Patent: July 4, 2017Assignee: Fresh Creek Technologies, Inc.Inventors: Dennis R.

Patent number: 9328499Abstract: An object of this invention is to provide an improved means of water treatment effectiveness. The invention strips floating and sinking particulates from flowing water with netting and inclined settling cells, which are arranged in an overlapping fashion to save treatment space. The effluent invert is virtually level with the influent invert to minimize pressure loss. The device pre-treats water for further treatment by filtering methods and among other application is ideally suited for applications where low depth profile treatment is beneficial or required.Type: GrantFiled: February 26, 2013Date of Patent: May 3, 2016Inventors: Gregory Stephen Duncan, Hans de Bruijn

Patent number: 7918996Abstract: The invention is a particle and sediment filter for stormwater. A long permeable filter bag is laid out horizontally within an enclosure. The bag is formed of at least two layers of parallel tubes that give each layer the pleated look of a typical air mattress. Stormwater is collected from the filter bag by perforated pipes held within the creases between the tubes of the layers of the bag, with the pipes draining to the outside of the enclosure. The bag is also supported above the bottom of the enclosure by additional perforated pipes located within the creases between the tubes, thus allowing the filtered liquid to also drain off beneath the bag. The stormwater input is from a pipe that feeds a manifold formed in the bag and connected to each tube. The top of the enclosure is removable for replacing the filter. The filter bags are constructed of flexible material so that they are flat during initial transport and installation, but they expand as they are filled with liquid and solid material.Type: GrantFiled: August 5, 2009Date of Patent: April 5, 2011Inventor: Hans de Bruijn

Patent number: 7798747Abstract: The apparatus is an underground reservoir to capture and slowly release stormwater runoff from impervious surfaces such as roads, rooftops, and parking areas. The structure is assembled from one or more modules comprising at least two side by side precast fiber reinforced concrete vaulted shaped chambers, each with side walls and an arch top. The side by side chambers have common walls with openings in the walls. Modules placed end to end are mated at reinforced concrete end walls that include lifting pins for moving the module. Ends of the chambers are closed, but the end walls have openings for feeding stormwater in and venting air out.Type: GrantFiled: October 30, 2006Date of Patent: September 21, 2010Assignee: Terre Hill Silo Co., Inc.Inventors: Hans de Bruijn, Dale Groff, E.

Patent number: 7121766Abstract: An underground structure liner based upon an inflatable liner structure. An acid resistant layer is the innermost layer of an inflatable liner, and the liner is coated with epoxy resin on its outermost surface, the surface which contacts the existing walls of the underground structure. The outermost coated surface of the liner is constructed with a fibrous fleece layer for better retention of the epoxy and better adhesion of the epoxy to the walls of the underground structure. An added feature of the liner is a structure which also seals the liner to pipes entering the underground structure.Type: GrantFiled: January 24, 2003Date of Patent: October 17, 2006Assignee: Terre Hill Silo CompanyInventors: Hans De Bruijn, Michael D. Zeiber

Patent number: 6676832Abstract: The apparatus is a surface water purifying catch basin which uses a lamella separator to separate out fine sediment and a separate chamber to trap heavy debris, oil, and floating debris. The surface water enters an inlet chamber which is separated from a settling chamber by a divider wall that has a lower opening between the chambers and a higher overflow. The inlet chamber traps floating contaminates and those that are heavier than the water. The opening between the chambers permits the surface water to flow into and through the lamella separator. The catch basin exit is from the settling chamber, but the water can reach the exit only through the lamella separator that separates out the fine sediment in the water. All of the accumulated contaminates can be removed through access holes in the top of the catch basin.Type: GrantFiled: January 5, 2002Date of Patent: January 13, 2004Assignee: Terre Hill Silo CompanyInventors: Hans de Bruijn, Dennis C.

Patent number: 4380282Abstract: A stacker for moving stone or other such material to the top of a pile by use of an endless belt conveyor. A long section of conveyor is rigged with converging suspension cables along its length to enable lifting the conveyor from a single point. With one end anchored and lifting near the center, the conveyor loading simulates static conditions as the other end is lifted above the discharge point. The central lift point is located at the top of a single mast which is leaned toward the anchored end of the conveyor. The combination of the angled mast and suspended conveyor section results in vector forces which give the assembly superior balance and stability and yields a conveyor support structure which is less costly and much lighter than previous designs.Type: GrantFiled: March 13, 1981Date of Patent: April 19, 1983Assignee: Aggregates Equipment, Inc.Inventor: Hans de Bruijn
