3 x 4ft Dewatering Bags With Drawstring

The 3 x 4 ft dewatering bag from FULEIYA features a non-woven geotextile fabric designed to filter contaminants, including sediment and oil, from water. It is described as reusable and easy to rinse after use, helping to extend service life on the job site. The bag’s filtration performance aims to prevent sediment discharge while maintaining site cleanliness. Its compact size makes it suitable for smaller projects or as a supplemental filtration unit during site dewatering operations.
4 x 6ft Large Dewatering Bag

The 4 x 6 ft dewatering bag from FULEIYA is designed to handle greater volumes than smaller models. Its non-woven geotextile fabric provides filtration to remove sludge, silt, oil, and garbage from water, reducing sediment discharge on site. The bag is described as reusable and capable of withstanding repeated use after rinsing, making it a practical option for ongoing dewatering tasks in larger projects.
5 x 10ft Dewatering Bag

This 5 x 10 ft dewatering bag from FULEIYA offers a larger filtration area, suitable for bigger job sites with significant sediment and oil content. The non-woven geotextile material aims to filter contaminants and separate impurities, helping to maintain cleaner water discharge. The bag is highlighted for durability and extended service life through repeated rinsing and reuse.
UltraTech 9724-OS Dewatering Bag

UltraTech 9724-OS is designed for oil and sediment dewatering with a 6′ x 6′ footprint. The bag aims to retain oil and sediment while allowing discharge water to pass. Its large capacity makes it well-suited for mid-to-large projects where substantial dewatering is required. The product emphasizes durability and reusability, supporting repeated use over time.
UltraTech 9725-OS Dewatering Bag

The UltraTech 9725-OS offers a large dewatering solution capable of retaining oil and sediment while supporting discharge hoses up to 4 inches. Its sizeable 15′ x 10′ dimensions make it a fit for substantial sites where water with sediment and oil must be processed efficiently. The bag emphasizes reusability and resilience for repeated use on multiple projects.
Buying Guide: Key Purchase Considerations
Consider the following factors when selecting a dewatering bag for silt, sediment, and oil control:
- Filtration efficiency: Look for non-woven geotextile fabric designed to capture fine sediment and impurities while allowing water to pass.
- Capacity and size: Choose a bag size that matches site flow rates and the volume of water to dewater. Larger bags reduce the frequency of emptying but require more space.
- Durability and reuse: Bags should resist tearing and provide reliable performance after repeated rinsing to maximize long-term value.
- Ease of use: Drawstrings, handles, and simple setup help improve workflow and site safety during dewatering operations.
- Chemical and oil compatibility: For sites with oil or hydrocarbon contaminants, ensure the bag’s filtration media handles oil retention without compromising material integrity.
- Discharge hose compatibility: Verify that the bag accommodates standard hose sizes (e.g., up to 4 inches) to connect with pumps and drainage systems.
- Maintenance requirements: Assess cleaning and maintenance steps needed between uses to prevent buildup and clogging.
- Environmental impact: Reusable options reduce waste; consider products with durable materials designed for multiple deployments.
- On-site conditions: Consider weather, terrain, and access when selecting bag size and handling features.
- Cost of ownership: Include initial purchase, expected lifespan, and number of uses to evaluate overall value.
