2. Pond liner - Wikipedia

   en.wikipedia.org/wiki/Pond_liner

   Pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, geotextiles (particularly needle-punched nonwovens) and other materials. Pond liners are manufactured in rolls or accordion-folded on pallets.

3. Evaporation pond - Wikipedia

   en.wikipedia.org/wiki/Evaporation_pond

   Each pond liner is prone to leakage and requires regular maintenance. [2] The contents of the evaporation pond depend on the use, the evaporation pond will contain water and the desired contents hoping to be extracted. The desired contents range from waste to minerals, and the remaining contents are either stored or extracted. [2]

4. Geosynthetic clay liner - Wikipedia

   en.wikipedia.org/wiki/Geosynthetic_clay_liner

   Geosynthetic clay liners (GCLs) are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. Due to environmental laws, any seepage from landfills must be collected and ...

5. Geocomposite - Wikipedia

   en.wikipedia.org/wiki/Geocomposite

   Such geocomposites are regularly used in intercepting and conveying leachate in landfill liner and cover systems and for conducting vapor or water beneath pond liners of various types. [3] These drainage geocomposites also make effective drains to intercept water in a capillary zone where frost heave or salt migration is a problem.

6. Waste stabilization pond - Wikipedia

   en.wikipedia.org/wiki/Waste_stabilization_pond

   This significantly decreases the load of organic matter that goes to the facultative ponds, and thus decreases their required size. [4] Anaerobic stabilization ponds have the disadvantage of potentially releasing malodorous gases. This especially includes hydrogen sulfide with an odor of rotten eggs, if the system has operational problems. [14]
