De-Silting Filters
Manufactured in the UK by Cowens. Specialist de-silting and sediment dewatering filter bags engineered to catch silt, sand, and suspended solids during site pumping, trench dewatering, and lagoon maintenance.
Dewatering Silt Filter Bags
Cowens de-silting filter bags connect directly to the discharge hose of submersible pumps. Fabricated from heavy-duty, high-flow non-woven geotextile filter media, they capture fine suspended sediments while releasing clean filtered water directly into surface drains or watercourses.
- ✔ Direct hose connection via heavy-duty clamp sleeve fittings
- ✔ High particle retention down to fine micron levels
- ✔ Cost-effective alternative to settlement tanks and vacuum tankers
- ✔ Helps maintain compliance with Environment Agency water discharge rules
Bespoke & Industrial Dewatering
Designed for heavy civil engineering, pipeline dewatering, and lagoon desilting operations. Custom dimensions and multi-stage filtration options allow high pump flow rates while keeping sediment discharge within environmental limits.
- ✔ High tensile strength lock-stitched seams resist bursting under pressure
- ✔ Accommodates standard 2″, 3″, 4″, and 6″ pump discharge hoses
- ✔ Reusable and easy to dispose of once fully loaded with sediment
- ✔ Bespoke sizing manufactured to fit specific site flow requirements
Applications & Specifications
Reliable sediment filtration for civil engineering, utilities, and marine maintenance.
Primary Applications
- Trench & Excavation Dewatering: Filters groundwater pumped out during pipe laying and foundation works.
- Pond & Lagoon Desilting: Contains fine organic mud and silt removed during lake restoration.
- Construction Site Runoff: Prevents silt-laden pump discharge from fouling stormwater drainage networks.
- Utility & Vault Maintenance: Quick-deploy filtration for manhole and vault water extraction.
Key Engineering Features
- High-Flow Geotextile: Engineered porosity prevents blinding while trapping fine particulates.
- Secure Neck Sleeve: Built-in double tie points prevent hose slippage during high-volume pumping.
- Durable Lock-Stitching: Reinforced synthetic stitching holds up in demanding jobsite conditions.
- UK Factory Direct: Custom sizes engineered and manufactured at our Carlisle facility.
