The Dewatering Staple of Bishop Water

Geotube® technology covers a range of dewatering purposes – from industrial to municipal wastewater treatment. A Geotube® container is a geotextile dewatering solution made from dual filament, polypropylene fabric. Geotube® technology is built to the requirements of each specific project, meaning it is tailored to tackle any dewatering challenge.

As sludge is pumped into the Geotube® it is injected with a polymer to separate the solids from liquids.  With our partner Geo-Dredging and Dewatering we use specially tailored polymer systems that are designed for optimal performance with the Geotube®. Many of them provide real time data feedback to help the client with their reporting. This step in the Geotube® Dewatering process is known as Containment.

Following Containment, Dewatering occurs immediately. Filtered effluent begins to flow through the material of the Geotube®, while the fabric liner keeps the solids trapped inside. The filtrate is then directed to a lagoon or a wastewater treatment facility. We are also able to provide mobile treatment systems to treat the water and discharge. The solids are retained inside the Geotube, typical solids retention is 99.5%.

After Geotube® Dewatering occurs, the Consolidation stage takes place. This natural zero energy process can be over a period ranging from immediate to longer than a year, it all depends on the project requirements and the client’s needs. During this stage of the Geotube® Dewatering process, the solids inside the Geotube® begin to break down. Once consolidation is complete, the Geotube® Dewatering process is finished. The consolidated sludge can be used in a variety of different ways some examples, as a soil amendment, composting, or even disposal at the landfill.

Our Geotube® has several features that makes it stand apart from other geotextile containers.

GP-4 Port

This is an innovative connection to improve and simplify filling your Geotube® container. While the filling port can be a weak point in other designs, the GP-4 Port is comprised of 1″ thick inside and outside flange rings that sandwich the GT500 textile between 1/8″ thick rubber gaskets and is secured with 5/8″ bolts. This increases the operating safety during pumping.

Circumferential Seaming

This patented seaming reduces the stress on the seams which allows for higher pumping heights and a higher factor of safety than longitudinal seams. When a geotextile container is being filled, the greatest stress goes across the fabric from side to side.  When longitudinal seams are used, the stress is pulling the seams apart as it is being filled. Circumferential seaming also allows for any circumference to be created without introducing additional seams.
