AQUVEXIS Water Treatment Architecture
Engineering Reference · Industrial & Process
Platform: AQUVEXIS™
Technology: ADSOVEX™ · MEMBRAVEX™ · IONVEXA™
Engineering Relationships
- AQUVEXIS™ organizes industrial water treatment by treatment mechanism rather than by one universal filter form.
- Depth Filtration addresses suspended particulate through depth-media capture.
- ADSOVEX™ addresses selected dissolved constituents through application-qualified adsorptive carbon media.
- MEMBRAVEX™ covers membrane-separation paths including reverse osmosis, ultrafiltration and nanofiltration.
- IONVEXA™ addresses selective ionic removal through ion-exchange media.
- Electrodeionization is a descriptive treatment family for electrically assisted ionic polishing after suitable pretreatment.
- Feed-water analysis, pretreatment, fouling potential, pressure, recovery, compatibility and required product-water quality govern selection.
- Performance standards and test methods are applied according to the specific treatment mechanism and product scope.
Components
- Depth-filtration element
- Activated-carbon treatment media or element
- Membrane element
- Ion-exchange resin or cartridge
- Electrodeionization module where applicable
- Water-quality sampling and monitoring points
Problems
- Suspended solids
- Dissolved organic or oxidant challenge
- Dissolved salts
- Hardness or target ionic species
- Membrane fouling or scaling
- Product-water quality instability
Failure Modes
- Treatment mechanism does not match the contaminant
- Pretreatment is insufficient
- Media or membrane loading exceeds duty
- Scaling, fouling or channeling develops
- Ion-exchange capacity is exhausted
- Product-water verification is not representative
Symptoms
- Outlet turbidity or solids increase
- Adsorptive breakthrough occurs
- Permeate quality degrades
- Pressure demand or differential pressure increases
- Ionic leakage increases
- Service interval shortens unexpectedly
Root Causes
- Feed-water condition differs from the selection basis
- Inadequate upstream particulate control
- Incompatible chemistry or oxidant exposure
- Scaling or fouling potential not controlled
- Treatment media exhausted
- Incorrect flow, recovery or regeneration duty
Diagnostic Methods
- Characterize feed and product water under representative conditions.
- Separate suspended, dissolved organic, ionic and membrane-separation challenges.
- Trend flow, pressure, differential pressure, conductivity and quality indicators appropriate to the treatment stage.
- Review pretreatment, fouling, scaling and chemical compatibility.
- Confirm media, element or membrane condition against the selected duty.
- Verify results with an applicable standard or validated project test method.
Corrective Actions
- Correct the upstream source or pretreatment deficiency.
- Select the AQUVEXIS™ treatment path that matches the confirmed contaminant mechanism.
- Requalify element, media or membrane duty for actual flow and water chemistry.
- Correct scaling, fouling, channeling or regeneration problems.
- Replace exhausted treatment media or elements using condition and performance evidence.
- Verify the post-treatment result using an applicable test method.
Maintenance Procedures
- Trend inlet and outlet water quality under comparable conditions.
- Monitor pressure, differential pressure and flow as appropriate to the treatment stage.
- Inspect element seating, seals, media condition and membrane integrity at service.
- Maintain representative sampling and analytical methods.
- Investigate shortened media or element life before changing treatment aggressiveness.
Operating Conditions
- Feed-water composition
- Suspended and dissolved contaminant loading
- Flow and pressure
- Temperature
- pH and oxidant exposure
- Fouling and scaling potential
- Required product-water quality
- Treatment recovery and service strategy
