.. A secondary wastewater effluent having a total organic carbon (TOC) concentration of 12 g/m3 is to be treated further by activated carbon adsorption. The objective is produce water having no more than 1.0 g/m TOC. Determine the amount of a carbon that would be necessary per cubic meter of secondary effluent if the carbon characteristics were those of (a) carbon A in Problem 4 and (b) carbon B in the same problem. Assume the system is a batch process.
