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.
