Abstract: An erosion barrier wastewater treatment system and in particular a liner for a wastewater treatment lagoon that provides for trapped gas below the barrier to be released through vents within the barrier and in particular to a liner for a wastewater treatment lagoon that may have portions replaced without operation of the wastewater lagoon facility being interrupted.

Abstract: A buoyant water heating device that may be used in a natural setting, such as a pond or lake, or in a man-made water-containing apparatus, such as a pool or water-treatment lagoon. The device comprises a water-filled, generally cylindrical anchor member coupled to a hollow, generally annular base member, and may he used alone or in combination with multiple other devices to create a free-floating blanket on the surface of the water. The device absorbs solar energy to heat water external to the device, and also provides a layer of thermal insulation between the water and the air above the device.

Abstract: A barrier which can be easily deployed in a lagoon, pool or other containment structure to partition and provide isolation between adjacent bodies of water or other liquid. As a result, different treatment operations can occur in the adjacent bodies of water which are separated by the novel curtain barrier. The bodies of water can also be easily rearranged by use of the invention. The barrier includes first and second curtains of flexible water impermeable material which are disposed in a generally vertical disposition and the bottoms of which are joined to a bottom web which preferably is integrally formed with the first and second curtains. The bottom web is adapted to be disposed on the lagoon bottom and ballast material is contained between the first and second curtains on the bottom web to seal the barrier to the lagoon bottom and to prevent movement of the barrier in response to wind, tide, current or other forces.

Abstract: An oil containment boom capable of maintaining a generally vertical orientation in water is disclosed. The containment boom includes a longitudinally extending curtain maintained vertically in the water by floats positioned in pairs in opposed relation along each side of the curtain. The floats are attached by a tether which extends through an opening in the curtain. The tether is capable of reciprocating motion through the opening in the curtain, which allows the floats of each pair to maintain positions in the water which are vertically offset from each other. When the water level on one side of the curtain is higher than on the other side, the float on the high water side rises to a higher position than the float on the opposite side and tends to pull the curtain back into a vertical orientation. The curtain may also include a weight along its lower edge. The self-righting feature of the present oil boom helps to prevent contaminants from washing over the top of the boom in rough areas.

Abstract: A marine barrier adapted for deployment as a curtain to divert the flow of water or for use as an oil containment boom and a method for installation thereof. The barrier typically includes a vertically disposed curtain having floats positioned in opposed relation along each side thereof in an outrigger configuration, and parallel, spaced, vertically aligned reinforcing ribs disposed within pockets formed on the surface of the curtain. The bottom edge of the curtain may be weighted with ballast to maintain its vertical orientation. When the barrier is used for diversion purposes, the bottom edge is anchored preferably by self-burying anchors. Typically, a plurality of parallel barriers are employed in a staggered configuration so as to create a baffle through which the water must flow. The diversion barrier typically is anchored along one edge to the shore and along another edge to a post within the body of water.
