Influent Characterization

PFAS, matrix, flow, target.

Declare the PFAS analyte set, measured concentration range, water matrix, flow envelope, and treatment or compliance objective that will govern the carbon evaluation.

Nächste Entscheidung

Decide what pretreatment is needed to protect the carbon bed.

Engineering-Fragen

Which PFAS compounds, chain lengths, and concentration ranges govern?
What DOC/TOC, TDS, pH, temperature, and competing adsorbates are present?
Which seasonal or event-driven flow and quality cases must the vessels handle?

Randbedingungen / Auslegungsaspekte

PFAS adsorption depends on compound, chain length, functional group, carbon type, and water matrix; a PFAS total alone is not a design basis.
DOC/TOC and other organic matter compete for carbon capacity and can change service behavior.
No dedicated ATLAS calculation tool currently covers PFAS species, chain-length, trace-level ng/L, matrix, or treatment-target characterization; establish this basis from representative analytical and project data before adsorption design.

Pretreatment

Solids, organics, bed protection.

Zweck

Assess whether solids, colloid, or selected organic-load pretreatment is warranted to protect bed hydraulics and reduce avoidable fouling or competition.

Nächste Entscheidung

Fit or select a media basis before sizing the vessel.

Engineering-Fragen

What suspended solids, colloids, oils, or organic load reach the carbon?
Would a selected UF/MF or chemical-conditioning step measurably improve the carbon-feed basis?
What residuals and post-treatment samples are needed to validate the pretreatment effect?

Randbedingungen / Auslegungsaspekte

UF/MF area and backwash sizing do not predict particle or PFAS removal efficiency; verify treated-water quality with project data.
The dosing calculator calculates a declared dose and batch basis; it does not select a chemical or predict coagulation, DOC removal, or PFAS response.
Pretreatment can change DOC competition, fouling, and residuals; establish the benefit with representative jar, pilot, or operating data.

Werkzeuge für diese Stufe

Stufe 03 · Adsorption

Adsorption Sizing

Lab capacity, EBCT, bed design.

Zweck

Separate equilibrium adsorption screening from GAC contact and vessel sizing, then establish an explicit preliminary geometry and capacity/load basis.

Nächste Entscheidung

Choose a vessel arrangement and operating monitoring plan.

Engineering-Fragen

Which representative-media capacity basis is defensible at relevant concentrations and matrix conditions?
What EBCT, superficial velocity, carbon mass, vessel dimensions, and pressure drop are being screened?
Is a capacity/load-based nominal life estimate adequate for this decision, or is project-specific pilot breakthrough evidence required?

Randbedingungen / Auslegungsaspekte

Activated Carbon Sizing uses user-entered contaminant concentrations, target outlet, adsorption capacities, target life, density, grain size, and vessel geometry to calculate preliminary mass, bed-volume, EBCT, velocity, pressure drop, and a capacity/load-based estimated life.
That estimated life is not a PFAS breakthrough curve or validated field bed life; the tool does not model PFAS-specific chain-length behavior, competitive adsorption, DOC/TOC competition, pilot data, or lead/lag behavior.
Isotherm fitting is laboratory equilibrium interpretation. It can inform a capacity assumption but does not predict field breakthrough or media life.

Werkzeuge für diese Stufe

Verfügbar Aktivkohle-Dimensionierung Primary: screen entered capacity/loading and vessel inputs for carbon mass, bed volume, EBCT, velocity, pressure drop, and capacity-based estimated life; it does not predict PFAS breakthrough. Werkzeug öffnen Verfügbar Vorläufiges Isothermen-Screening Supporting: fit laboratory bottle-point Ce/qe data with Freundlich, Langmuir, or BET models; not a field breakthrough or bed-life predictor.

Engineering-Fragen

Which target PFAS, sample points, analytical methods, and detection limits define the monitoring basis?
What sampling frequency and operating flow/pressure records reveal changes in performance?

Randbedingungen / Auslegungsaspekte

Laboratory isotherm interpretation is not a field breakthrough model; it must not be used as an unvalidated field service-life prediction.
Observed breakthrough depends on PFAS species and chain length, DOC/TOC competition, pretreatment, carbon properties, hydraulics/channeling, and operating history.
No current ATLAS tool analyzes PFAS monitoring time series, predicts a breakthrough curve, or estimates a validated field changeout date.

Replacement or Regeneration

PFAS-loaded media disposition.

Zweck

Document a changeout, reactivation/regeneration, disposal, or destruction route from observed performance and the spent-media contaminant basis.

Nächste Entscheidung

Carry the documented media decision into procurement, operations, and regulatory review.

Engineering-Fragen

What measured evidence authorizes changeout or regeneration?
How will spent PFAS-loaded carbon be characterized, transported, permitted, and accepted?
Does the proposed regeneration or destruction route validate PFAS destruction and control secondary residuals?

Wichtige Eingaben

Wichtige Ausgaben

Randbedingungen / Auslegungsaspekte

Adsorption transfers PFAS to the spent carbon; it does not destroy PFAS.
Spent media handling, transport, regeneration, disposal, and destruction validation depend on the specific contaminant record, jurisdiction, vendor process, and permits.
Changeout timing is an operating decision based on measured evidence; no current ATLAS calculator determines disposal route or validates PFAS destruction.
