Abstract

The waste water analyzed in several rivers and streams of the south of Quito show a high concentration of fat and oils, even exceeding the maximum permissible limits and the problem of it are the low rate of degradation, also makes harder the biological treatment and cause operational problems in the wastewater treatment plants. In view of this problem, it has been proposed to evaluate the efficiency of the lipase of Aspergillus niger immobilized in calcium alginate in the pre-treatment of the wastewater coming from Shanshayacu creek since the conventional treatments used in the case of fats have two disadvantages either a low efficiency or in turn a very high cost. The percentage reduction in total fat content was determined and analyzed as a result of the enzymatic pre-treatment. Finally a reduction of 54% in the total fat content was achieved. In this way it was concluded that the pretreatment shows important results that demonstrate the efficiency of the same and the advantages that it provides over conventional treatments.
