Influent Characterization

PFAS, matrix, flow, target.

目的

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

次の判断

Decide what pretreatment is needed to protect the carbon bed.

エンジニアリング上の問い

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?

主な出力

Declared DOC/TOC and competing-load basismg/L

制約 / 設計上の考慮事項

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.

目的

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

次の判断

Fit or select a media basis before sizing the vessel.

エンジニアリング上の問い

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?

主な入力

Feed and candidate carbon-feed TOCmg/L

主な出力

Validated carbon-feed turbidity basisNTU
Validated carbon-feed DOC/TOC basismg/L

制約 / 設計上の考慮事項

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.

Adsorption Sizing

Lab capacity, EBCT, bed design.

目的

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

次の判断

Choose a vessel arrangement and operating monitoring plan.

エンジニアリング上の問い

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?

主な入力

主な出力

制約 / 設計上の考慮事項

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.

この段階のツール

公開中 活性炭サイジング 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. ツールを開く公開中 吸着等温線の初期スクリーニング Supporting: fit laboratory bottle-point Ce/qe data with Freundlich, Langmuir, or BET models; not a field breakthrough or bed-life predictor. ツールを開く

Lead/Lag Carbon Vessels

Lead/lag sequence and triggers.

目的

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

次の判断

Define breakthrough monitoring and the evidence needed for changeout.

エンジニアリング上の問い

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?
How will isolation, bypass, equalization, and vessel changeover affect continuity and compliance?

主な出力

制約 / 設計上の考慮事項

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.

目的

Use compound-specific samples and operating records to detect observed breakthrough, assess lead/lag protection, and define a changeout review trigger.

次の判断

Review replacement, disposal, or regeneration based on measured evidence.

エンジニアリング上の問い

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?
What validated result triggers lag-vessel transfer, media changeout, or immediate response?

主な入力

主な出力

制約 / 設計上の考慮事項

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.

目的

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

次の判断

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

エンジニアリング上の問い

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?

主な入力

Compound-specific breakthrough / effluent recordsite basis
Cumulative treated volume and operating historym³
Spent-media PFAS characterizationsite basis
Spent-media co-contaminant / matrix contextsite basis

主な出力

Observed service period and changeout basisdays
Documented spent-media handling and disposition routedesign / compliance basis

制約 / 設計上の考慮事項

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.
