Material Selection

A wide variety of engineering applications make use of different materials, depending upon their usage. The materials used in civil engineering vary in their properties such as strength, ductility, brittleness, and creep strength. Depending upon the application and external loading conditions, an engineer must make a wise decision for material selection. A wrong decision would fail in its functionality.

1. A company produces wastewater containing an organic contaminant during eight hours every day at a flow rate of 1000 L/hour. The wastewater is to be treated by carbon adsorption. The waste concentration is 35 mg/L and a 90% removal is to be achieved. Two different carbon types were tested for the application and the isotherms for the contaminant on the different carbon types are given below. You are asked to choose the most economical carbon for each of two possible reactor configurations (assume all carbon types cost the same). Treatment choices are: i. A batch reactor that is big enough to hold the wastewater for one working day (=8 hours). Assume the kinetics are fast enough so that the carbon will reach equilibrium overnight. The reactor will be emptied and cleaned early the next morning and will be ready to be refilled with the wastewater produced that day. ii. fixed bed adsorber columns, arranged in series, such that the first column in the process stream is allowed to become…
