PROCESS TRAIN

Every unit has a job

Follow the complete treatment train from raw influent to final effluent. Click any unit to learn what enters, what changes, what leaves, and what to watch.

ACTIVATED SLUDGE LAB

Food → microorganisms → oxygen → clearer water

Follow the core story of the biological process. The model links loading, biomass, aeration, and separation without issuing real plant commands.

01

Food enters

230 lb/day

Flow carries BOD into the learning model.

02

Microorganisms respond

6,000 lb

Aeration volume holds an estimated biomass inventory.

03

Oxygen supports work

2.0 mg/L DO

Oxygen availability changes the activity story.

04

Clarified water leaves

92% clarity

Outlet reflects SVI and effluent TSS.

BIOLOGY / MICROSCOPE LAB

Meet the microbial community

Connect operating conditions with floc behavior. These are simplified visual categories, not species diagnoses.

teaching view

Compact aggregates settle well and support a clearer supernatant.

Healthy operation
food availability + oxygen + enough biomass + good settling
Use this view to ask better questions. It cannot identify exact microbial species or replace microscopy and laboratory review.
SECONDARY CLARIFIER LAB

Watch solids separate

Run a compressed 30-second settling observation. Change SVI, MLSS, RAS, or WAS in the overview panel and return to see the behavior respond.

Understand the numbers

Every result shows its equation, live value, step breakdown, interpretation, and teaching note. Ranges are not universal operating limits.

CORE EQUATIONS

Reference panel

US customary
Food load FF = Q × BOD × 8.34lb/day
Biomass inventory MM = V × MLVSS × 8.34lb
Food-to-microorganismF/M = F ÷ Mratio
Sludge volume indexSVI = (SV30 × 1000) ÷ MLSSmL/g
Volatile solids fractionMLVSS ÷ MLSSratio
Hydraulic retention timeHRT = V ÷ Q × 24hours
RAS solidsQras × Conc × 8.34lb/day
WAS solidsQwas × MLSS × 8.34lb/day
The factor 8.34 is the US customary water loading conversion used by this educational model.

Educational model only. Verify decisions with approved procedures, laboratory data, engineering review, permit requirements, and site-specific limits.
SCENARIO LAB

Train your operator instincts

Each condition loads real local values into the same model. Reveal the explanation, then ask what evidence would confirm the story.

OPERATOR TRAINING MODE

Pause. Observe. Confirm.

Ten short situations practice the habit of checking trends and context before treating a simplified indicator as a control instruction.

TRAINING PRINCIPLE

Evidence before action

The preferred choices emphasize trend confirmation, laboratory context, equipment condition, and approved procedures.

MODEL ASSUMPTIONS / ABOUT

A transparent teaching model

AquaForge is designed to make process relationships visible, not to impersonate a SCADA system.

EDUCATIONAL DISCLAIMER

Use the model to learn, not to issue commands.

This simulator is intended for education and visualization. It is not a substitute for approved plant operating procedures, laboratory testing, engineering review, permit requirements, or site-specific process control limits.

F/M, SVI, MLSS, MLVSS, RAS, WAS, DO, and clarity interpretations are simplified teaching models. Actual operating decisions require trends, laboratory data, equipment condition, and site-specific guidance.

MODEL NOTES

What is simplified here

  • US customary loading factor 8.34.
  • Simplified steady-state mass and volume relationships.
  • Simplified clarifier settling, blanket, and clarity behavior.
  • Educational classification thresholds, not universal limits.
  • No real plant data connection or automatic control commands.
  • RAS and WAS calculations use the local teaching assumptions shown in the sheet.
When a value looks surprising, inspect the formula and the input first. The warning is intentionally visible.
