Please upload your full solution to the following problem. Calculate the bed life, volume of water treated, minimum carbon usage rate (CUR), and maximum specific throughput for trichloroethene (TCE) given the following design specifications: Influent concentration = 1 mg/L TCE . Carbon type: Calgon Filtrasorb 400 (12 x 40 mesh); Pb = 450 g/L • Freundlich parameters for TCE • Freundlich capacity parameter K = 55.9 (mg/g)(L/mg)¹/n • Freundlich intensity parameter 1/n = 0.48 Treatment objective = 0.005 mg/L TCE Flow rate=378.5 L/min (100 gal/min) Empty bed contact (EBCT) = 10 min . . . . Assume that no other solutes compete with TCE for adsorption onto the GAC, and that the GAC is saturated at the influent concentration.

Biological Processes

Biological solid waste includes bacterial and contaminated waste produced by living individuals. Its treatment is essential to prevent the spread of any air-borne or water-borne diseases or diseases transmitted from one organism to another in a food chain. There are many benefits of the biological solid waste treatment and some of them are: the minimized quantity of waste substance, waste control, eradicating any disease-causing pathogens, generation of biogas, composting, anaerobic digestion, bio drying, mechanical biological treatment, microbial fuel cell, phytoremediation, and biofiltration. The final products of the biological solid waste treatment may be recycled to obtain organic fertilizers or disposed of in SWDS (Solid Waste Disposal Site) after proper treatment.
