A starting point for review.
Discuss requirements for applications including wastewater, industrial sludge, mining and aggregates, construction, and remediation.
Use these guideline specifications as a starting point, then review your material and operation with Bulk-Pack. Confirm the current design, load rating, availability, and operating instructions for the bag you order.
Dimensions and capacities are guidelines only. Bulk-Pack can help size the right bag for your material and process.

Your process information helps frame the fabric, construction, and handling questions that need to be resolved.
Material & liquid
Describe the solids and liquid, their compatibility requirements, temperature, and any relevant material documentation.
Particle size & retention
Share the particle-size distribution and the solids you need to retain. Ask for fabric performance information relevant to your material.
Drainage & process
Define the liquid volume, desired drainage time, filling method, and how performance will be evaluated in your process.
Support & liquid collection
Show us the bag support arrangement, drainage area, and how the released liquid will be collected and handled.
Weight & handling
Specify the maximum contents weight during filling and handling, lifting equipment, clearances, and unloading method.
Quantity & documentation
Include expected usage, delivery location, drawings, required records, and the documentation your operation needs.

How is a dewatering FIBC different from a containment bag?
A dewatering design uses uncoated fabric to let liquid drain while retaining solids. Tell us whether your process needs drainage, liquid containment, or another function so the construction can be reviewed.
What particle size will the bag retain?
Request the filtration and retention data for the proposed fabric. Confirm the retention characteristics for the specific fabric and construction. Share your particle-size distribution and define how retention will be checked with your material.
How quickly will the liquid drain?
Drainage performance must be evaluated for the particular material and bag design. Share your material, solids concentration, operating conditions, and required cycle time so the team can review the application and any evaluation needed.
Can the bag be reused?
Reuse must be reviewed for the specific bag design and application. Confirm the instructions, inspection criteria, material compatibility, and suitability for another use with Bulk-Pack before planning reuse.
Does a dewatering bag qualify for hazardous materials transport?
Do not infer transport qualification from the dewatering function or listed capacity. Share your material classification, proposed shipment, and required packaging documentation for a separate review.
Can you help with a different size or configuration?
Send your current drawing or describe the process. We can review the required dimensions, filling and discharge details, fabric, handling arrangement, and design options with you.
