Coal Ash Processing


Product:         Geotube® Dewatering Technology

Application:   Mining & Mineral Processing

Location:       Wellston, Ohio

Installation:   2001


The Challenge:

A coal washing plant needed to simplify its dewatering operation and lower the related costs.

The Solution:

Their existing method of mechanical dewatering was old and inefficient.  It was replaced with the high-volume, low-maintenance Geotube® dewatering technology.  The Geotube® dewatering system utilized a project height of 5 feet for the dewatering containers [photo 2]. 

The Results:

The coal sludge dewatered to 63% solids inside the Geotube® units.  The project achieved nice results with improved quality of effluent water [photo 5].
