4. Many industries are required to pre-treat "high strength" wastewaters before discharge a municipal wastewater treatment system. Wastewater is produced at a winery at ate of 227,000Ld1 from a winery has a TOC concentration of 400mgL1 and the allowable discharge limit for TOC is 35mgL1. A pilot column breakthrough test with activated carbon was conducted with the purpose of designing a granular activated carbon adsorption contactor to treat the winery wastewater. Pertinent design data for the test column are: Inside diameter 0.095m Length 1.04m Mass of carbon 2.98kg Volumetric flowrate 17.42Lhr1 Bulk activated carbon density 401gL The following data were collected for effluent concentration of TOC as a function of throughput volume. (a) (2 pts) Plot the breakthrough curve for the column test (b) (6 pts) Calculate operating parameters for the column test (i) Empty bed contact time (h) (ii) Bed volume turnovers per hour (h1) (iii) Superficial velocity (mh1) (iv) Breakthrough volume (L) (v) Time to bed exhaustion (0.95Cinlet) (vi) Length of the active mass transfer zone, Z3, (m) 4.
