A wastewater treatment facility in Johannesburg, South Africa, is treating effluent from a chemical manufacturing plant that produces specialty chemicals for the mining industry. The effluent from the chemical plant flows at 200 m3 /day with an organic pollutant concentration of πΆπ = 60 ππ/πΏ being fed to an adsorption column with activated carbon to obtain concentration of πΆπ = 1 ππ/πΏ in the effluent. The following data is given: π·π = 0.800 π, ππ = 70 ππ πππ πππππ‘π/π3 πππ, πΎ = 0.9 π3 πππ/ππ πππ ππππππ‘ β β 2.1Calculate the required height of the column for 6 days of operation. (15) 2.2If the void fraction in the column is π = 0.3, determine the volume of required activated carbon. (6) 2.3For π» = 5 π, for how long can the column be operated to obtain effluent adsorbate, C?
