Patent application numberDescriptionPublished
20090294356BACKWASHING UNSATURATED WASTEWATER FILTER - A compact high efficiency combined biological and physical unsaturated wastewater treatment filter configured for periodic backwashing is disclosed. The filter utilizes packed media and removes pollutants and pathogens from wastewater and other dirty water sources. The filter comprises a periodic backwashing means to less the chance that biofilm growth will clog the media pores. However, such backwashing still leaves sufficient biofilm attached to the media to maintain a very high level of treatment. In the preferred embodiment, the filter utilizes high frequency dosing to cause pore saturation at or near the surface during dosing and shortly thereafter in order to maximize distribution uniformity and to induce downward airflow into the media. The system provides a number of unexpected benefits; including allowing a very low distribution pressure and providing high oxygen transfer at low energy utilization into the filter media for aerobic biodegradation of pollutants.12-03-2009
20130168331Means for Cleaning Packed Media In a Wastewater Filter Treatment System - A highly efficient means for progressively backwashing and fluidizing filter media in packed media filtration systems utilized for removing contaminants from wastewater is disclosed. The means is suited for use with a generally unsaturated filter with air and water flowing concurrently in a downward direction during treatment. During periodic backwashing, a pump provides treated wastewater from a holding tank to an underdrain and a pressurized water jet configured as an eductor within the filter vessel to progressively fluidize, backwash and redistribute the media. Fluidized media flow induced by the water jet is turbulently transported to the top of the filter vessel in an upflow pipe, wherein excess biofilm is scoured from the media. Scoured biofilm leaves the filter with backwash water through an overflow conduit and an exit port. Backwashing removes excess solids caught in the filter media and controls the biofilm thickness and the nature of the biofilm.07-04-2013

Patent application numberDescriptionPublished
20090235589BREAKAWAY ELEMENTS FOR A HORIZONTAL SIDE-MOVING DOOR - A horizontal side-moving door with a side-winding curtain or horizontally translating panel includes a breakaway brace that helps hold a relatively rigid leading edge of the curtain or panel in a substantially vertical orientation. Should a forklift accidentally strike the leading edge of the curtain or panel, a replaceable shear pin incorporated in the brace breaks away to release the leading edge, thus protecting the edge from damage. Although the shear pin can break into two or more pieces, the brace includes means for holding the pieces in place and preventing them from falling and hitting anything underneath the pin. Although with some limitations, the door is still operational even while the pin is broken.09-24-2009
20090236051BOTTOM SEALS FOR A HORIZONTAL SIDE-ROLLING DOOR CURTAIN - A sideways rollup door with a horizontal side-rolling curtain includes a replaceable bottom seal that is zippered or otherwise removably connected to the curtain at an inclined joint. The inclination of the joint ensures that the joint wraps upon the curtain's take-up roller in an approximate helical pattern so as to prevent the joint from creating a concentrated bulge on the roller. In some cases, there is extra space underneath the roller to provide roll-up room for the bottom seal, which can be relatively thick. Such extra space could be further used to accommodate a seal joint and/or other curtain seams that are not necessarily inclined.09-24-2009
20090236052PLIABLE SHROUDS FOR A HORIZONTAL SIDE-ROLLING DOOR - A sideways rollup door with a horizontal side-rolling curtain includes a vertical roller that is shielded by a pliable shroud. The shroud is supported by a frame that includes a breakaway feature and/or readily replaceable frame elements. To access the roller for servicing, the frame elements allow the shroud to be selectively moved (without the use of tools) between an installed position and a retracted position. In some cases, the breakaway feature enables the shroud to break away in certain directions easier than others. In some embodiments, the shroud includes a seal that engages the curtain when the shroud is in the installed position.09-24-2009
20100218429UPPER SEAL FOR A HORIZONTAL SIDE-MOVING DOOR - An example of a horizontal side-moving door with a side-winding or horizontally translating curtain includes an upper seal comprising an upper edge of the curtain sliding within a groove of a seal guide. To protect the door in the event of an impact, at least a portion of the curtain's upper edge can restorably pull out from within the groove. To avoid damage in certain situations, the seal guide might resiliently deflect as well. After an impact, the curtain's upper edge is automatically fed back into the groove by simply opening and closing the door. During normal operation, the curtain's upper edge advantageously deflects in response to air pressure against either side of the door. In some examples, the seal guide is of a uniform cross-section, which makes the seal guide easy to manufacture by way of a conventional plastic extrusion process.09-02-2010
