Texas Wastewater Class B Prep
TCEQ practice by process
Free · Designed for iPad. Not verified for macOS.
Practice by treatment process — preliminary, secondary, solids, disinfection — so you can see which part of the plant you still need to work on.
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
