CARRENO SAYAGO, Uriel Fernando. Design and evaluation of a biosystem water treatment pilot-scale tannery through Eichhornia crassipes. Rev. colomb. biotecnol [online]. 2016, vol.18, n.2, pp.74-81. ISSN 0123-3475.  https://doi.org/10.15446/rev.colomb.biote.v18n2.52271.

From the environmental point of view, the sector of tanneries always has been catalogued like highly pollutant, where his productive process of the leather from a treatment leather physicist - chemist of animals generates chemical pollutants as the chrome and organic waste that cause environmental negative impacts on the ecosystems. The natural, such ecosystems as the wetlands, they are the most productive systems in the world as result of the abundance of light, water, nutrients. Due to this abundance and favorabilidad is common to find the presence of plants that have developed morphologic and biochemical adjustments allowing them to take advantage to the maximum of the advantages of these conditions of his environment, which have been named commonly aquatic undergrowths. Between these floating undergrowths (macrofitas) one finds the Water hyacinth (Eichhornia crassipes), which has a wide presence in Cundinamarca's humid bodies (Colombia); they present a high invasive capacity developing a scattering raised in these aquatic systems. But this plant has the aptitude to transform the organic matter and especially accumulate different metals weighed in his morphology. In the present investigation, a biosistema of treatment was designed and constructed for the removal and retention of chrome of waters contaminated by the residues of the process of the tanneries, being the Eichhornia crassipes, the agent retainer of these pollutant compounds, where I demonstrate an economic and technologically viable solution for the industrial sector.

Keywords : Eichhornia crassipes; chrome; tanneries; biosistema.
