Dewatering

Wastewater is harmful to the environment due to the presence of high oxygen demanding material, nutrients, suspended solids, pathogenic organisms, organic compounds and other contaminants.

Sludge is produced in large amount in the process of wastewater treatment.  Sludge is typically subject to dewatering prior to disposal.   Dewatering serves the following purposes:

• Reduces volume, saving money on storage and transportation
• Eliminates free liquids before landfill disposal
• Reduces fuel requirements if the residuals are to be incinerated
or dried

Dewatering technology involves the use of Geotubes that functions as follows:

• Solids are contained inside the Geotube dewatering unit
• Water drains out of the Geotube dewatering unit
• Over time, allows further drying of biosolids to take place

At the end of the dewater use, the Geotube unit can be cut open, exposing highly dewatered solids that can be easily excavated and transported away.  Geotubes are available in a variety of sizes, depending on your volume and space requirements.
