## What is Texas Wastewater Class B Prep?

Practice for the TCEQ Wastewater Treatment Class B operator licensing exam, for operators working toward or renewing a Texas wastewater licence.

SORTED BY TREATMENT PROCESS
Most operator apps hand you one undifferentiated pile of questions. These 500 are sorted the way a plant actually runs, so a weak area is something you can find and drill:

- Preliminary & Primary Treatment — bar screens, grit removal, primary clarifiers, detention time
- Secondary & Biological Treatment — activated sludge, MLSS, F/M ratio, RAS and WAS, trickling filters, nitrification, SVI
- Solids Handling & Digestion — anaerobic digesters, volatile solids, thickening, dewatering, biosolids
- Disinfection & Effluent Quality — chlorination, dechlorination, UV, contact time, fecal coliform limits
- Laboratory & Process Control — sampling, pH, alkalinity, TSS, settleometer, jar tests
- Pumps, Equipment & Collection System — centrifugal and positive-displacement pumps, lift stations, I/I, blowers
- Safety & Regulations — confined space, H2S, lockout/tagout, TPDES permits, reporting
- Math & Calculations — MGD, loading rates, detention time, percent removal, dosage

HOW YOU STUDY
- Mock exam scored against a percentage pass mark, not a raw count
- Practice by process area when you want to work one topic at a time
- Missed and bookmarked questions collected automatically
- An explanation on every question, so a wrong answer teaches you the process
- Per-topic accuracy and coverage in the analytics
- Fully offline. No account, no sign-up.
