Single-Use Depth Filter Cartridge

 

The Single-Use Depth Filter Cartridge is used for clarification and solid-liquid separation in disposable or low-contamination processes.
It is built on a graded depth structure that captures particles throughout the filter media rather than only on the surface. This design helps reduce early clogging and supports more stable flow behavior during operation.
It is commonly installed as a pre-filtration or clarification step before membrane filtration or chromatography systems.

Graded Depth Filtration Structure
The media is formed with multiple filtration layers and gradually changing pore sizes. Larger particles are retained in the outer layer, while smaller particles are captured deeper inside the structure.
This distribution spreads solids loading across the full depth of the media, reducing surface blockage and improving effective utilization of the filter volume.

High Solids Retention Capacity
Compared with surface-type filters, depth filtration provides a larger internal void structure for particle capture.
In practical operation, this helps maintain usable flow for a longer period under higher solids conditions and reduces the frequency of filter replacement in batch processes.

Stable Performance Under Process Variation
In real production, feed conditions often change during operation, including solids concentration, particle size distribution, and viscosity.
The depth structure helps buffer these variations by preventing rapid surface fouling and maintaining a more controlled pressure rise profile.

Low Extractables Material Selection
All wetted materials are selected to minimize extractables and leachables. This supports use in sensitive bioprocess applications where product quality and contamination control are critical.

Structural Stability During Operation
A reinforced internal core supports the filter media under differential pressure. This helps maintain structural integrity during long filtration cycles and prevents deformation under load.

 

 

 

 

Filtration scaling and selection should never rely solely on a nominal micron rating. Optimal configuration requires evaluating specific feed characteristics and downstream process constraints.
50 µm – Bulk solids removal, primary harvesting, and high-load macro-clarification.
20 µm – General clarification of fermentation broths or primary industrial process liquids.
10 µm – Intermediate pre-filtration designed to shield fine secondary filtration stages.
5 µm – Fine particle reduction and bioburden lowering upstream of asymmetric membranes.
1 µm – Final polishing, haze removal, or sensitive downstream sterile filter protection.

 

 

Jiuling depth filter cartridges feature universal dimensional footprints conforming to global standards. They integrate seamlessly into:

• Standard multi-round industrial stainless steel housings.
• Single-use encapsulated plastic filtration assemblies.
• Inline, skid-mounted clarification systems.
• Pilot-scale and commercial production-scale process lines.

No structural system modification or re-engineering is required for standard retrofits.
