Slit-Film Dewatering Bags
South African manufacture and Africa-wide project supply, with fabric selection, dimensions and operating requirements matched to your slurry.
Slit-Film Dewatering Bags
Selected for your slurry. Manufactured for your project.
High-flow woven polypropylene tape fabrics combine filtration with directional tensile strength, including a 105 / 105 kN/m reference class. Select a bag using feed trials, the required filtrate and the complete fabricated assembly.
Product selection
Specifications that inform the right choice
Compare the published grades, then confirm the supplied construction and project requirements in the technical submission.
| FlowTex grade | Tensile MD/CD (kN/m) | O90 (µm) | Normal permeability (mm/s) | Mass (g/m²) |
|---|---|---|---|---|
| HF45 | 45 / 45 | 600 | 40 | 210 |
| HF60 | 60 / 60 | 600 | 27 | 280 |
| HF105 | 105 / 105 | 300 | 25 | 500 |
Technical notes and test basis
Nominal reference fabric values, subject to stated tolerances and the current project submission. Tensile: EN ISO 10319; O90: EN ISO 12956; normal permeability: EN ISO 11058; mass: EN ISO 9864. Fabric strength is not seam strength or allowable filling pressure.
From specification to site
Fabrication, QA/QC & African project supply
Filtration before assumptions
Compare the actual feed against candidate grades. Fine or colloidal particles may require conditioning or a composite liner even where the filter opening looks small.
Structural selection
Fabric tensile strength describes the roll material. Seams, ports, density, filled geometry and filling height determine the finished assembly assessment.
Installation and operation
Use a stable prepared drainage area and controlled filtrate collection. Agree the filling sequence, operating limits and solids-removal method before delivery.
FAQ
Frequently asked questions
Are FlowTex dewatering bags and tubes available from stock?
FlowTex holds stock for immediate supply. Ask for the available grade, dimensions and quantity; allocation is confirmed for the order. Custom dimensions or a different construction require a fabrication programme. Dispatch readiness and delivery time are confirmed separately.
What should I provide for a firm technical quotation?
Send the application, wet volume or flow, solids concentration and measurement basis, particle information, chemistry, filtrate target, dimensions, quantity, destination and required date. Identify any loaded handling requirement.
How is the fabric choice confirmed?
Compare published grade properties with representative slurry trials and the fabricated assembly requirements. The supplied construction, filling limits and handling arrangement are agreed for the actual project.
