A municipal wastewater flow of 1,000 m³/d contains 400 mg/L BOD5 and is treated to be in a trickling filter. The filter will use a plastic filter medium with a specific surface area of 200 m³/m² and will operate with a recirculation ratio of 100% and a hydraulic loading of 25 m³/m² -d. Based on a typical surface loading of 4 kg BOD5 /m²-d, what volume (m³) of plastic media would be required?

You need to answer in numerical form in two decimal places only unless otherwise specified. For problems having a whole number or zero as an answer, the decimal isn't necessary. For example, if your answer is 900, the decimal isn't necessary. No need to input the units, follow the units given by each problem. ROUNDING OFF VALUES MUST BE DONE ONLY IN THE FINAL ANSWER TO AVOID LARGE DISCREPANCIES. I'll rate!
