Benefits of technology
The present invention is a liner system for wastewater treatment facilities that saves money and time compared to traditional methods. The liner does not need to drain the lagoon or interrupt its operation. The liner is a skirt that surrounds the lagoon, but it does not need to cover the entire interior surface area of the lagoon. The skirt can be easily installed by securing panels together with a reinforced webbing strip instead of sealing each panel to the other. The liner is made in manageable sections and can be brought to the site and connected together. The liner is maintained in contact with the lagoon through vents to prevent air and gas from accumulating and causing problems.
Problems solved by technology
This is tremendously expensive where an entire lagoon system must be covered with a liner, not only upon initial construction but upon replacement or fixing of a compromised liner.
This of course means that the lagoon must be emptied and cannot be used for the time period in which the new liner material is placed inside.
It is tremendously labor intensive, time-consuming and expensive to assemble such liners and empty the lagoons if a liner needs to be fixed or replaced.
Traditional lagoon based liner systems may further suffer from rippling because of either aeration or the decomposition of organics in the soil that builds up air and gas below the liner and that prevents the liner from lying flat on the soil.
This rippling may cause further erosion where gaps between the liner and soil surface cause pathways for water to seep into and under the liner, removing soil as the water runs down the embankment.

Embodiment Construction
[0026]FIG. 1 is a diagrammatic representation of a wastewater treatment plant having a pretreatment process 110, a primary treatment process 120 and a secondary treatment process 130. The pretreatment 110 removes heavy materials such as trash, leaves, branches, etc., that can easily be collected from raw wastewater before damage is caused by clogging pumps or skimmers in the primary and secondary treatment processes. Pre-treatment may include screening the wastewater for such heavy materials by use of a screen or a rake passed through the wastewater to accumulate the heavier material on the screen which can then be removed manually or mechanically. Also, the flow of the wastewater may be adjusted to allow settlement of sand gravel, stones and broken glass for example. Particles of this type or kind can also damage pumps and other equipment in the treatment facility.
[0027]In primary treatment 120 the wastewater generally flows into large tanks called clarifiers, or sedimentation tank...

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.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part and claims the benefit of U.S. application Ser. No. 12 / 956,662 filed Nov. 30, 2010 entitled Erosion Barrier Method and Apparatus which is hereby incorporated in by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to an erosion barrier wastewater treatment system 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. The lagoon may be any earthen basin for containing a body of water, for instance wastewater, and the liner is utilized mainly for reducing the erosion of the lagoon walls due to water turbulence.BACKGROUND OF THE INVENTION[0003]Conventional lagoon based wastewater treatment systems rely generally on open air lagoons to permit aerobic and anaerobic...
