  • Patent number: 7309431
    Abstract: In a covered wastewater reservoir, a gas passage is defined under the membrane cover and along the sides of the reservoir. An accumulation of bio-gases is held captive between the membrane cover and the liquid surface in a central region of the reservoir relative to the gas passage, by a flap-valve attachment condition extending between the accumulation of bio-gases and the gas passage. The new method for breaking this flap-valve attachment condition and for allowing bio-gases to flow from the accumulation of bio-gases toward the gas passage, consists of periodically and momentarily increasing a pressure in the gas passage to equal or to slightly exceed a pressure in the accumulation of bio-gases. In another aspect, the membrane cover is provided with a stiff and rough-surfaced bottom layer to facilitate the breaking of flap-valve attachment conditions when the pressure under the cover is made equal everywhere.

  • Patent number: 7198433
    Abstract: The invention provides an improved method of collecting biogas from a landfill that results in more complete collection of biogas produced in the landfill, and with less contamination with air. The method involves providing the landfill with an upper gas containment layer near the surface of the landfill to retard biogas escape and air entrainment into the landfill. Underneath the gas containment layer is provided a gas-permeable conductive layer. Underneath the conductive layer, a well withdraws biogas from the landfill. Withdrawal of biogas from the well creates a partial vacuum that draws gas from the gas-permeable conductive layer down through the waste mass to the well. If the rate of gas withdrawal from the well is too rapid, air will be entrained from the atmosphere into the gas-permeable conductive layer. But if the rate of gas withdrawal from the well is too slow, biogas may percolate through the gas-containment layer and the surface of the landfill to escape.

  • Patent number: 7195425
    Abstract: Landfill daily cover and general ground cover is produced from sewer sludge and/or municipal solid waste by adding an amount of cellulose material to form a de-watered stream having a water content of about 55% or less by weight. The de-watered stream is then treated to reduce its pathogen concentration, preferably by first grinding the de-watered stream to form an average 10–50 mesh particle size stream that is then heat treated to further reduce the water content to 20%, preferably 5%–15%, by weight. To produce a daily cover a flame retardant material is added in amounts to qualify the end product as landfill daily cover.

    Abstract: Waste materials are composted in an elongate pit which is maintained covered to retain odors. The pit includes two rails each arranged along a respective side of the opening for receiving operating machines and a carriage for supplying a covering sheet. Each side edge of the sheet has attached thereto a channel shaped support member arranged for engaging over the respective rail so as to attach the side edge to the rail. A reel is mounted on the carriage and is arranged to roll the sheet and the two support members onto the reel and to un-roll the sheet and the two support members therefrom for deployment. An arch support bridges the support members and can flex to a flat condition from rolling on the reel. The carriage includes guides for moving the support members apart to a wider spacing for rolling on to the reel with the sheet flat and for guiding the support members onto the rails and for bowing the arch upwardly in the deployed position.

    Abstract: A cover assembly for an organic waste lagoon basin and a method of making and deploying such a cover assembly. A cover includes connected cover panels or sections. In one form of the invention the panels are comprised of a single layer of geotextile fabric. In another form of the invention the panels are comprised of interconnected strata including a sacrificial layer which faces the sun and protects the cover from ultraviolet light degradation; a foam layer that floats the cover; and a geotextile fabric layer. The geotextile fabric is porous and suppresses the release of malodorous gases from the lagoon basin. The cover can be constructed and deployed by laying out cover panels in fanfold fashion along a side of the basin; connecting adjacent edges of the panels; attaching flotation to the free edge of the top panel; and using deployment lines and a mandrel to move the cover across the filled basin.
