Dewatering and Draining Big Bags - Geotextile Sludge Bags

Geotextile filter bags for industrial purification and sludge treatment. PP fabric with calibrated porosity retains solids while allowing water drainage, reducing waste volumes by up to 70%. Tessuto geotessile 170 g/m² with 100-micron pore opening. Gravitational filtration: sludge is pumped in, water is filtered through the fabric, and solids are retained until complete dehydration. For civil/industrial treatment plants, ceramic plants (slip), quarries (wash water), chemical processes (precipitates), and construction sites (bentonite). Reinforced suspension system, optimised filling valves.

Technical Features

Tessuto doppio strato: Tessuto esterno finestrato PP 170 g/m² + TNT filtrante diametro particelle 100 micron.
Struttura ottimizzata: Geometria della trama anti-intasamento (autolimpieza) e sistema di sospensione rinforzato.
Bretelle potenziate: 4 loops per sollevamenti gravosi con portata 1500 kg cad.
Portata (SWL): Capacità 1000-1500 litri.
Drenaggio: Permeabilità drenaggio gravitazionale.
Base antistrappo: Rinforzo angolare per prevenzione rotture.
Riduzione volume: Riduzione volume 70%.

Available Configurations:

Selective drainage: Draining bottom (perforated base), controlled lateral drainage, total or sectoral permeability.

Key operational benefits:

360° cost reduction: 70% reduction in volumes and disposal costs, with an estimated ROI typically between 6-18 months.
Plant efficiency: Zero energy consumption, minimal maintenance, and the elimination of expensive traditional filtration systems.
Labour savings: Near-automated processes that reduce cycle times by eliminating long storage and sedimentation waiting phases.
Logistics and Cleaning: No dirty transport vehicles to wash or sanitise thanks to perfect containment during transit.

Applications

Purification and Chemistry: Sludge pumped from civil/industrial treatment plants, wastewater sediments and chemical precipitates.

Extractive and Ceramic Industry: Wash water for quarry aggregates, mineral concentration and ceramic slip.

Construction and Remediation: Soil washing from contaminated sites, bentonite for drilling and wet construction materials (mortars, cements).

Other: Agriculture (compost, manure), residual wastewater from industrial processing plants and sludge from vehicle washing.

Certifications:

Geotextile fabric compliant with EN 13249-13257.
Regulatory compliance with Legislative Decree 152/06 (Environmental Consolidation Act).
Certified permeability and hydraulic resistance tests.

Logistics Solutions: Filter Liners for Roll-off Containers

In addition to standard formats, custom-sized filter liners are available for the truck skip. This advanced logistics solution allows the dehydration process to be performed directly on board the vehicle, eliminating the time and costs of intermediate transfer operations. Furthermore, by acting as an internal protective lining, the fabric prevents direct contact between the sludge and the metal: this preserves the container from wear and removes the need for prolonged washing after each transport. The result is twofold economic savings, deriving both from lower resource consumption for cleaning and from the recovery of valuable working hours of the personnel involved.
