WaterSolve LLC, was tasked to provide technical assistance for the installation of a Geotextile tube container dewatering system at a large coal mine in western Colorado. Currently, some of the solids thickening/dewatering processes within the plant do not allow for the plant to operate at the desired capacity.

WaterSolve LLC was tasked to provide technical assistance for the installation of a Geotextile tube container dewatering system at an abandoned mine near Huntington, Utah.

Watersolve was contracted to assist in the testing, start-up, and optimization of the chemical feed components of the treatment system. The 2011 season was the third for this treatment system designed to remove arsenic and other containments from the water. Since the site was in a remote location all of the equipment, products and supplies were delivered to the site via ice roads or cargo plane. The products provided by WaterSolve included Geotextile tube containers, filtration fabric, and chemicals.

This new sand mine in Missouri chose a Geotextile dewatering system to remove the solids from the wash water so the water could be recycled through the plant. The Geotextile tube containers offered the most cost-effective process to clean the 5,000-GPM flow coming from the plant. Solids were captured in the tubes and the water returned to a 2-acre pond for recycling through the plant to wash the sand clean.

A company in charge of treating the wastewater generated from a decommissioned gold mine in British Columbia had to come up with a solution to comply with new solids disposal regulations. WaterSolve, LLC was contracted to provide the necessary supplies, equipment, and technical support for a full-scale trial using Geotextile tube container technology.

Gold deposits were discovered at the Nevada mine in 1864. Before any new mining operations could begin they  needed to repair the pregnant and barren pond liners to meet regulatory requirements.

Runoff water from a stockpile of gold mining rock had a pH of 2.3 and was very acidic. A small water treatment plant was built to treat this water and capture the metals prior to sending it to the city’s wastewater treatment plant. Geotextile tube containers provide a low-cost solution to capture the residual and save the city from this highly toxic water entering their wastewater stream.

Geotube® Containment and Dewatering technology was used to dispose of slurry waste from North River Mine.

Geotextile tube containers were selected to dewater the sediment dredged from a lagoon at this Ohio steel manufacturing plant in the fall of 2008. The objective was to remove the material from the lagoon and dewater it to pass a paint filter test for subsequent hauling to a landfill. WaterSolve, LLC furnished the personnel to monitor the polymer injection throughout the project as well as the equipment and supplies to for the Geotextile tube dewatering system.

A stormwater retention basin in a Kentucky stone quarry had accumulated sediment and needed to be cleaned to restore the storage capacity during rain events. In a two week time period a dredge filled 1,100 linear ft of Geotextile tube with the chemically conditioned sediment. The dewatered material reached 85% dry wt solids at the completion of the project.

This copper mine in Utah annually removes solids from its wash-water sediment pond and now prefers dredging the residuals and dewatering them in Geotextile tube containers prior to processing them through the plant to reclaim the precious metals. WaterSolve, LLC provides the polymer make-down equipment, polymer, Geotextile tube containers, and site management for the tubes. The mine has reduced the risk of puncturing the liner along with heavy fines caused by previous excavation processes.
