Evaluación de la capacidad de algas chlorophyta para remover materia orgánica en aguas residuales del Camal Municipal del cantón Shushufindi.

Abstract

This research focuses on evaluating the ability of Cholorophyta seaweed to remove organic material in sewage water from the Municipal slaughterhouse of Shushufindi Canton, taking into account the worldwide interest in the cultivation of microseaweed for energy purposes, attached to the need to have environmentally more sustainable sewage water treatment technologies. Seaweed isolated from the Limoncocha lagoon was cultivated in a tubular photobioreactor, 6 experimental units of 1.8L were constructed with 5 replications. Growth tests we made by sowing in Foliar Nitrofosca cultivation between with aeration and without aeration; organic material reduction tests by sowing seaweed in sewage water from slaughterhouse with dilution 1:3 with aeration and without aeration; two experimental units without seaweed, one with aeration and another aeration used as target. A 12-hour photoperiod was used approximately 800 Lux LED lamps, a temperature of 22.38 ± 2.3° C and pH of 8,45 ± 0.22. The most efficient treatment for the removal of BOD5, phosphates and total nitrogen Kjeldahl was the cultivation of seaweed in sewage water from slaughterhouse 1:3 with aeration, with 83.1% ± 5.9; 58,9 % ± 7.7 and 63.1% ± 2.3 respectively, providing a celular productivity of seaweed obtained with Nitrofoska Foliar with aeration that it was 39061 cells/ L.day, which demonstrating that the sewage water from the Municipal slaughterhouse of Shushufindi Canton constitutes a more efficient cultivation way for the production of seaweed biomass. For the removal of sulfates, the cultivation in sewage water from slaughterhouse without aeration showed greater efficiency with 58.9% ± 7.7 removal. The residual seaweed biomass produced by the treatment can constitute a valuable raw material for the production of bioenergy, animal feed, biofertilizers of other value-added products.
