AQUVEXIS Depth Filtration
Engineering Reference · Industrial & Process
Platform: AQUVEXIS™
Engineering Relationships
- Depth Filtration addresses suspended solids by capturing particulate through the thickness of a porous medium.
- Element selection depends on particle loading, target outlet condition, flow, allowable pressure drop and downstream sensitivity.
- Depth-media efficiency and capacity are product-specific and cannot be inferred from nominal micron wording alone.
- Depth Filtration can serve as standalone particulate control or pretreatment ahead of downstream water-treatment stages.
Components
- Depth-filtration element
- Housing interface and seals
- Differential-pressure monitoring point
- Upstream and downstream sampling points
Problems
- Suspended solids
- Premature downstream fouling
- Rapid element plugging
- Solids breakthrough
Failure Modes
- Element loading beyond duty
- Incorrect media grade
- Seal or seating bypass
- Flow above qualified range
Symptoms
- Differential pressure rises rapidly
- Outlet solids increase
- Service interval shortens
- Downstream equipment fouls
Root Causes
- Feed solids exceed design basis
- Particle distribution changed
- Element area is insufficient
- Housing bypass or seal defect
Diagnostic Methods
- Characterize feed solids and required outlet condition.
- Trend differential pressure at comparable flow.
- Inspect element seating and seals.
- Compare actual flow and loading with the selection basis.
Corrective Actions
- Correct upstream solids source where practical.
- Requalify media grade and element area.
- Correct seal or seating defects.
- Verify downstream water condition after service.
Maintenance Procedures
- Trend differential pressure.
- Inspect used elements for loading pattern and bypass evidence.
- Preserve representative water sampling.
- Investigate unexpectedly short element life.
Operating Conditions
- Feed-water solids loading
- Particle-size distribution
- Flow
- Allowable differential pressure
- Temperature
- Required outlet condition
- Housing interface
Standards
- ISO 20468-1:2018 — general performance-evaluation framework where depth filtration is part of a water-reuse treatment system.
- No universal ISO element-performance standard is assigned across generic AQUVEXIS depth cartridges; removal efficiency, capacity and differential-pressure claims require validated product-specific test evidence.
