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

Próxima decisión

Decide what pretreatment is needed to protect the carbon bed.

Preguntas de ingeniería

Restricciones / consideraciones de diseño

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.

Etapa 02 · Pretratamiento

Pretreatment

Solids, organics, bed protection.

Propósito

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

Próxima decisión

Fit or select a media basis before sizing the vessel.

Preguntas de ingeniería

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?

Restricciones / consideraciones de diseño

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.

Herramientas para esta etapa

Abrir herramienta Disponible Calculadora de Base de Dosificación Química Conditional: calculate feed rate and batch mixing only after a compatible pretreatment chemical and dose are selected from project testing.

Etapa 03 · Adsorción

Adsorption Sizing

Lab capacity, EBCT, bed design.

Propósito

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

Próxima decisión

Choose a vessel arrangement and operating monitoring plan.

Preguntas de ingeniería

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?

Restricciones / consideraciones de diseño

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.

Herramientas para esta etapa

Disponible Dimensionamiento de Carbón Activado 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. Abrir herramienta Disponible Evaluación Preliminar de Isotermas Supporting: fit laboratory bottle-point Ce/qe data with Freundlich, Langmuir, or BET models; not a field breakthrough or bed-life predictor.

Lead/Lag Carbon Vessels

Lead/lag sequence and triggers.

Propósito

Define the lead/lag operating architecture, sampling access, isolation/bypass logic, and changeout response needed to manage observed breakthrough.

Próxima decisión

Preguntas de ingeniería

How many vessels and what lead/lag sequence protect the required response time?
Which influent, inter-vessel, and final-effluent sample points and changeout triggers apply?

Restricciones / consideraciones de diseño

Lead/lag can provide a protective response window only when vessel sizing, sampling, triggers, and operations are validated together.
No current ATLAS tool models vessel-array operation, inter-vessel sampling, bypass/changeover logic, or response-time assurance.

Breakthrough Monitoring

Compound-specific sampling.

Propósito

Preguntas de ingeniería

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?

Restricciones / consideraciones de diseño

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.

Etapa 06 · Residuos

Replacement or Regeneration

PFAS-loaded media disposition.

Propósito

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

Próxima decisión

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

Preguntas de ingeniería

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?

Salidas clave

Restricciones / consideraciones de diseño

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.
