To prepare the wastewater effluent from Pasveer’s MF filters (Problem 19-7) for groundwater discharge, it will passed through an activated carbon filter. Assuming a conservative EBCT, estimate the volume of activated carbon required for a column.

Problem 19-7

Estimate MF filter area required to treat effluent from the Pasveer tertiary filter (Problem 19-5). Assume a conservative hydraulic loading

Problem 19-5

A dual media denitrification filter is being considered for the effluent from the oxidation ditch being built for the city of Pasveer (Problem 16-28, Chapter 16). Using the data from Pasveer and a permit requirement that NO₃ -N not exceed 4.0 mg/L, determine the following:

a. Filter media volume

b. Filter hydraulic loading

c. Number of filters and their nominal dimensions

d. Methanol dose in mg/L and kg/d

Assume a typical NO₃-N loading rate for the sustained minimum temperature and assume that the filters will be sized using the guidance in Chapter 8.

Problem 16-28

Estimate the volume of an extended-aeration oxidation ditch for carbonaceous BOD oxidation and nitrification for the city of Pasveer using the following design data:
