Product: Geotube® Dewatering Technology
Application: Light Industrial
Mexico's largest chicken processing plant was experiencing high levels of BOD discharge into a local river because their two on-site lagoons were full of solids. Federal regulations required immediate action to remove the solids.
Geotube® containers were chosen because they could be rapidly deployed and were capable of removing large volumes of solids in a short period of time.
An on-site baseball field was converted to a 200' x 300' dewatering cell. An impermeable liner was placed on the field surface, followed by a three-dimensional mat to enhance drainage [photo 2]. Once the site preparation was complete, two layers of Geotube® containers (90' circulation x 188' long) were installed and the dewatering began immediately [photo 3].
Within 90 days, 16 million gallons of waste materials were dewatered. The two on-site lagoons were restored to proper operating levels, and the BOD in discharge was below permitted levels.
The sludge continued to dewater in the Geotube® containers and later was made available to local farmers for fertilizer.
