Subsequently in situ points water contamination was determined by using Cr, point is specifically identified in the wastewater generated in the phase in mention. To know the amount of Cr present in the wastewater from the tanning process the laboratory analysis was performed, determining the presence of Cr in 2643,208 mg/L, Value exceeding the maximum permissible limits of TULSMA environmental regulations, VI book, I appendix, 11 table, says the allowable limits for discharge Cr public sewer system is 0.5 mg/L. |
