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. Taking both surface loading and volumetric loading criteria into consideration, what volume (m³) of plastic media should be installed?

Hello

Would you please solve this question.

I got the results but it is incorrect 

466.8 m^3, 20,000 m^3, 64,000 m^3 all are incorrect.

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. Taking both surface loading and volumetric loading criteria into
consideration, what volume (m³) of plastic media should be installed?
