Before entering sewer, corrosive liquids must pass through which process?

• A. Dilution/Neutralization
• B. Filtration
• C. Chlorination
• D. Sedimentation

Answer: (A)

Reducing corrosive potential before sewer entry is accomplished by dilution or neutralization. The idea is to lower the strength of the chemical and adjust its acidity or basicity so the liquid won’t damage sewer pipes, pumps, or equipment, and so it won’t upset the downstream treatment process. Dilution cuts the concentration, while neutralization uses a chemical to bring the pH into a safe range for the sewer system. Other processes like filtration, chlorination, or sedimentation address solids or disinfection rather than neutralizing chemical corrosivity, so they don’t fit this purpose.
