The Geotube technology works by allowing sludge to be filtered through the unique dual filament polypropylene fabric, while retaining a high percent of solids. As sludge is pumped into a Geotube unit, it is injected with a polymer. The addition of the polymer to the sludge is necessary to flocculate the sludge and allow the Geotube technology to dewater as effectively as possible.
