This economical low energy sludge drying system can be used to dewater a variety of municipal contaminated wastewater treatment plants and industrial waste sediments.
Offering a non-mechanical method of dewatering, sludge from the pond is pumped into the tubes, solids and fine particles are retained while clear filtrate is released through the porous material of the tube.
GeoPro™ Tubes are fabricated with both monofilament and multifilament yarns to produce a high-strength woven polypropylene (PP) fabric. Its specialist weaving structure ensures the right balance between high permeability and solids retention.
Dewatering runs in cycles: fill, drain, repeat. Each fill consolidates the retained solids further, so the process needs time and a prepared laydown area with containment and a filtrate return path. Tubes are a passive system — they trade speed for low energy use and minimal plant. Where a site needs immediate volume reduction in hours rather than days, mechanical dewatering is the better fit.
Polymer selection is not optional. The correct flocculant for the specific sediment is what makes the fill-and-drain cycle work; the wrong one blinds the fabric and stalls the tube.
GeoPro™ Desludging Tubes and skip bin tubes are available in a number of sizes to suit each project’s needs.
Offering a non-mechanical method of dewatering, sludge from the water
body is pumped directly into the GeoPro™ Tubes. Solids and fine particles
are retained, while clear filtrate water is released through the porous
material of the tube back into the waterway.
GeoPro™ Tubes can be stacked in a pyramid formation to maximise space efficiency. This approach aligns with environmental best practices, ensuring compliance with water quality standards while minimising ecological impact.
Skip Bin Tubes are a versatile dewatering tube option designed to fit neatly in a standard skip bin or a roll-on/off hook bin. Offering convenience and ease of use, Skip Bin Tubes are an ideal option for built-up sites, sites with limited space or on projects requiring easy disposal of captured solids. They are also popular on medium-sized projects or projects with ongoing dewatering needs.
APEX Envirocare was engaged to carry out dredging and desludging works on a Waste Water Treatment Plant pond in the heart of WA’s Wheatbelt region.
Our approach involved specialist dredge equipment with advanced features designed to handle challenging WWTP conditions.
