ADSOVEX Adsorptive Carbon Treatment

Engineering Reference · Industrial & Process

Platform: AQUVEXIS™

Technology: ADSOVEX™

Engineering Relationships

  • ADSOVEX™ uses application-qualified adsorptive carbon media for selected dissolved constituents and residual oxidants.
  • Carbon media properties such as particle size, ash and iodine number characterize the media but do not by themselves prove capacity for every target contaminant.
  • Breakthrough depends on target chemistry, concentration, competing constituents, contact conditions and media loading.
  • Pretreatment and solids control can materially affect carbon-bed or carbon-element service behavior.

Components

  • Activated-carbon media or element
  • Housing or media-retention interface
  • Upstream particulate pretreatment where required
  • Inlet and outlet sampling points

Problems

  • Selected dissolved-organic challenge
  • Residual oxidant challenge
  • Premature breakthrough
  • Excessive media pressure drop

Failure Modes

  • Media not matched to target chemistry
  • Capacity exhausted
  • Competing constituents consume capacity
  • Particulate loading blinds the media

Symptoms

  • Target constituent appears downstream
  • Service interval shortens
  • Pressure drop rises
  • Outlet quality becomes unstable

Root Causes

  • Feed chemistry changed
  • Media capacity undersized
  • Contact conditions insufficient
  • Pretreatment ineffective

Diagnostic Methods

  • Identify target constituent and inlet concentration.
  • Review competing species and contact conditions.
  • Trend target breakthrough with media duty.
  • Inspect particulate loading and pressure drop.

Corrective Actions

  • Correct upstream contamination where practical.
  • Requalify carbon media against the target chemistry.
  • Requalify media quantity and contact duty.
  • Improve particulate pretreatment where required.

Maintenance Procedures

  • Trend inlet/outlet target constituent.
  • Track media duty and breakthrough.
  • Inspect loading and flow distribution.
  • Replace media using validated service criteria.

Operating Conditions

  • Target constituent
  • Inlet concentration
  • Water chemistry
  • Competing constituents
  • Flow and contact conditions
  • Temperature and pH
  • Particulate loading

Standards

  • ASTM D4607-14 — iodine number of activated carbon as a relative porosity indicator; it is not a universal measure of adsorption capacity for other species.
  • ASTM D2862-16(2022) — particle-size distribution of granular activated carbon.
  • ASTM D2866-11(2025) — total ash content of activated carbon.
  • ISO 20468-1:2018 — general treatment-performance evaluation where ADSOVEX™ is used within a water-reuse system.
