While geomembranes may offer the best combination of durability and flexibility for wastewater containment, they’re not all equally suited for this particular use.
Most wastewater management projects involve a mix of different holding units depending on which stage of treatment or storage is needed.
There is a lot of overlap between the various goals of storing, containing, and treating wastewater.
All projects involving short- or long-term exposure to water require durable materials.
Containment for wastewater, especially hazardous materials, goes beyond just holding it in a simple tank or lined pond.
Wastewater is generated by dozens of different industries on a daily basis.
While wastewater is often a valuable source of moisture for irrigation or other purposes, it also poses a wide range of hazards.
The marketing materials of alternative cover options like floating ballasts may convince you that geomembrane floating covers require a lot of maintenance.
Approving the use of a floating cover made from geomembrane for your project isn’t the only step in design or selection.
If digging and lining a pond sounds like a lot of work, it’s also possible to choose pre-formed vaults and tanks to hold fresh water or waste products.
The majority of covered ponds and lagoons in use today are covered with a system known as the defined sump/tensioned plate design.
Geomembranes certainly work well as floating covers, especially when built with the right materials from the start.
While there are dozens of potential, unique uses for floating covers made from geomembranes like RPE, most of them can be easily sorted into the categories of fresh and wastewater storage.
With such a wide range of uses and potential benefits, it’s not surprising that floating covers are installed on ponds and tanks in dozens of different industries.
Floating covers for reservoirs and lagoons are often compared to the simple solar or winter covers used on backyard pools.
Between drains, pumps, plumbing and maintenance ports, mining ponds often feature multiple penetrations through the sides and bottom of the geomembrane liner.
In addition to protecting the ground from seepage with buried liners, mining facilities need to consider stopping rain from infiltrating heaps of raw material.
Evaporation ponds are widely used throughout the various branches of the mining industry.
While geomembranes are practically required by many of today’s modern mining projects, they’re not without installation considerations.
With so many uses for geomembranes in the mining industry, during both active and closed stages of a project, it’s no wonder they’re so widely used.
It’s not enough to simply specify certain mining geomembranes during the original construction of a mine.
In addition to being universally popular for road construction and pond lining projects alike, geomembranes are essential for the mining industry.
You’ll find dozens of mentions of geomembranes in the recommendations and standards for mining facilities in most states, but the exact definition of this term isn’t always clear.
One of the biggest benefits of using quality, flexible geomembrane liners in sewage lagoons is the improvements to the sludge removal process.
A sewage lagoon may look like it’s operating the same as it always has while water is secretly leaking out of a low quality, cracked liner.
