Innovative Design of Sludge Drying Beds Using 3D GEOWEB® Geocells

Wastewater treatment facilities have long had to contend with the challenge of dewatering sludge to minimize waste and achieve overall cost efficiency for disposal. Large-scale facilities commonly use mechanical filter presses or centrifuges to dewater sludge. This equipment is often too cumbersome and expensive for many smaller facilities, so they rely on sand filter drying beds for sludge dewatering. Because small tractors or loaders cannot be operated on the loose sands of a conventional drying bed, a system must be implemented to stabilize the sand and improve load distribution for routine cleanout operations. Transforming Infill Material with the GEOWEB® Geocells Through an interconnected honeycomb-like network, 3D geocells confine and stabilize soils that would otherwise be unstable under loading conditions. Geocells are efficient and economical for fast-built unpaved roadways and retaining walls, erosion control of slopes, and stormwater channel protection. The GEOWEB® 3D Stabilization System is the industry’s most complete geocell system, designed with fully engineered components to withstand the most challenging site problems. Made from robust high-density polyethylene (HDPE) since conception, GEOWEB geocells offer the highest, longest-lasting, and most proven performance of any geocell system in civil applications.

Building Energy Roads in Harsh Conditions With the GEOWEB System

Energy sites are often located in remote and difficult to access sites in environments with poor soils, limited road-building resources, and extreme weather conditions. Site Challenges in Western Canada In Western Canada’s Oil Sands region, transporting construction equipment, drilling rigs, and completions apparatus – all with heavy wheel loads (typical loads exceeding 125,000 lbs) is the challenge. It can be extremely difficult to accomplish this over the soft, wet ground (thick muskeg and saturated clays) typical of this region. Add the challenge of working in the dead of winter in below-zero temperatures and on frozen ground, with limited road building materials, and the scenario makes accessing the sites extremely difficult. In the wettest months, muddy conditions can make access by heavy trucks and equipment nearly impossible. So, energy companies typically wait for the ground to freeze before ramping back up construction.  Even in winter, access to remote oil sites creates challenges including undeveloped roads, soft ground, and scarce materials suitable for constructing roads. A Road Solution Built for Extreme Conditions The GEOWEB® 3D soil confinement system is built for these challenges.  The all-weather HDPE material is fast to install and isn’t hindered by soft ground or extreme temperatures.
