This study guide leads readers through the types of math problems that appear on grade three and four wastewater treatment certification tests. Approximately 120 problems are addressed, divided among the two levels, and include: solids and hydraulic loading rate calculations, dosage problems, pressure problems, sludge production calculations, and basic electricity problems. Each problem is immediately followed by a solution and procedure, and the two levels are each concluded with a practice test followed by explanation. Appendices contain a summary of the wastewater treatment equations, relevant chemistry tables, a depth-to-diameter table, and flow charts of wastewater treatment processes.
