Geomembrane

Zero Energy Institute and its partners provides clients with complete Geomembrane design and installation services for both landfill and wastewater containment applications.

 

Landfill

 

The most common type of solids containment is the landfill for storing waste products. In this application, geomembrane liners are installed under the waste to prevent leachate from escaping, and typically have caps to minimize water infiltration and leachate creation.  Although municipal solid waste is a common geomembrane application, other  landfill types abound. Landfills can contain ash, sludge, spent catalyst, or other waste products. In mining the slag heaps from mineral processing may use liners or covers. Fertilizer manufacture produces almost as much gypsum as fertilizer and lined gypsum stacks are common. Sulfur storage on geomembranes is now common with many sulphur storage facilities now using geomembranes as liners under sulfur blocks.

 

Wastewater

 

Effluent treatment lagoons use geomembrane liners to store large quantities of contaminated water until the natural bacteria have enough time to break down the products of contamination.  Effluent treatment is commonly used in sewage lagoons, process water ponds, industrial waste water ponds, run-off ponds, spill ponds and in dump ponds. Sediment and settling ponds trap silt to reduce the amount of suspended solids transferred to treatment lagoons.  These types of ponds need to be cleaned out occasionally and often need to have additional inputs such as aeration, flocculation, or pH adjustment additive systems.  An effluent treatment pond can either work continuously as part of a process, such as a sewage lagoon, or it can be periodically measured, neutralized and released as part of a run off pond.
