ABSTRACT
This paper contributes
to the Industrial Ecology Concept by using a common urban solid waste,
i.e., coffee residues, to clean industrial wastewaters polluted by basic dyes,
e.g., Methylene Blue. For the data from the continuous fixed-bed column system,
two common models, namely (a) Bohart and Adams and (b) Clark were implemented.
The Bohart and Adams capacity was up to N = 46,166
mg·L-1 or q0 = 104.5 mg·g-1 for bed-depth 15
cm, initial dye concentration 800 mg·L-1 and flow rate 20 mL·min-1.
The results revealed that the Methylene Blue is fairly adsorbed on coffee
residues. Consequently, this process can be applied as a low cost technique for
cleaning basic dyes from the aquatic environment.
KEYWORDS
