Our range of dewatering MacTubes® are tubular geotextile containers that are used to increase the efficiency of the dewatering of slurries. They enable the on-site treatment of a wide range of both natural and contaminated fluid sludges. Dewatering features MacTube® geosynthetic tubes which are filled in-situ with a pumped slurry; the fluid drains through the fabric walls, leaving the solid residues within the tube. Once the residue has dried it can be disposed of far more safely and cost effectively than wet, slurried material. The use of site-specific flocculants is common to accelerate the filtration process.
The dewatering and drying of sludge is a technology with low environmental impact and cost.
