High-Strength Anaerobic Wastewater Treatment Designer

Screen a characterized, biodegradable high-strength industrial feed against a selected anaerobic reactor basis; treatability and post-treatment evidence remain explicit.

Status
Available

STAGE 04 · BIOLOGICAL TREATMENT

High-strength anaerobic screening and design basis

Use characterized influent, selected technology criteria, and declared treatment evidence. Missing evidence stays visible.

Engineering boundaryNo design criteria or performance values are preloaded. Total COD, BOD, or their ratio does not establish anaerobic treatability. OLR/HRT/upflow values and declared performance require a traceable project, laboratory, BMP, pilot, vendor, observed, or reference basis.

01 · REACTOR / CASE BASIS

Process configuration

Stage 04 remains an optional biological branch.

One-unit-out reduces the declared duty train by one. Standby volume is not credited unless a separate operating scenario explicitly puts it in service.

02 · FLOW CASES

Hydraulic flow basis

Peak Hour is hourly; bounded Event is not annualized.
Flow provenance

This provenance record is applied to the enabled named flow cases when you calculate.

03 · INFLUENT CHARACTERIZATION

Average Daily characterization

Measured / characterized values only.

No missing constituent is treated as zero. pH does not predict alkalinity, neutralization demand, or treatment stability.

Sample and treatability provenance

04 · EXPLICIT DESIGN CRITERIA

Loading, HRT and hydraulic basis

No universal values are supplied.
Design-criteria provenance

When calculating, the selected criteria provenance is applied to OLR, HRT, working-volume and plan-area criteria; granular upflow applies only to UASB/EGSB.

05 · INFLUENT CHARACTERIZATION

Case-specific COD and supporting water quality

Unentered values remain NOT CALCULATED.

06 · TREATABILITY / PERFORMANCE

No treatment prediction from COD strength.
Performance provenance

This performance provenance is copied to the named cases that contain a declared removal or effluent value.

No kinetic correction or chemistry prediction.

Sulfate is displayed as a review parameter. No sulfate reduction, sulfide generation, toxicity, VFA accumulation, or acidification is predicted.

11 · BIOGAS / METHANE BASIS

Declared yield only

Gas reference condition is explicit; no gas-unit conversion is implied.

12 · RESIDUALS BASIS

Optional anaerobic sludge basis

No generic biomass yield is applied.

This is not PRIMARY_SLUDGE, BIOLOGICAL_WAS, SCREENINGS, or GRIT. Integrated residuals processing remains with the Wastewater Sludge & Residuals Designer.

13 · DOWNSTREAM AEROBIC HANDOFF

Manual effluent-basis package

No automatic runtime handoff or downstream recalculation.

Case-specific temperature, pH, alkalinity, ammonia-N, total N, and total P are supplied in influent characterization and pass through only when entered for this selected handoff case.

Remaining biodegradable COD provenance

Enter this basis only when the anaerobic effluent biodegradable COD was independently characterized.

Engineering Basis

Methodology

Screen a characterized high-strength wastewater feed against explicit reactor criteria, treatability evidence, and declared performance. No universal loading criteria or treatment prediction is supplied.

Standards / Reference Basis

US EPA AgSTAR Anaerobic Digester/Biogas System Operator Guidebook (2020), Sections 3.1–3.5: operating context and test-specific methane-potential basis; not an industrial UASB/EGSB design criterion.

Assumptions

  • Calculates case-based COD loads, OLR and HRT volumes, simple UASB/EGSB hydraulic checks, explicit recycle throughput, duty and one-unit-out capacity, declared COD removal, and methane/biogas only from a supplied yield and gas condition. Total COD, BOD, or their ratio does not establish anaerobic treatability. Reactor internals, toxicity, inhibition, startup, permit compliance, and aerobic downstream calculations remain outside scope.

Scope / Limitations
