Biorremedación de los efluentes líquidos en la producción de almidón de yuca Manihot esculenta Crantz en el cantón Chone - Manabí 2009

One of the biggest problems facing cassava producers and processors is the effluents generated during the starch extraction process, which cause negative impacts in the areas due to their high pollutant load. This study aimed to generate bioremediation alternatives for liquid effluents from cassava starch production in the Chone canton, San Pablo de Tarugo site. This was achieved through wastewater monitoring, identifying the appropriate dose and frequency for the application of efficient microorganisms, identifying environmental liabilities, and conducting an economic estimate of the best treatment. This research demonstrated that efficient microorganisms (EM) reduce the pollutant load of liquid effluents from cassava starch production by 71.5% in COD and BOD, total solids and suspended solids by 91.5%; phosphate by 98.6%, nitrate by 72.4%, and nitrogen by 52.3%. Furthermore, the use of EM significantly reduces unpleasant odors due to the reduction of the nitrate variable. Likewise, daily environmental liabilities were identified: husk, bagasse, and sludge, with production volumes of 224, 637, and 21 kg/day, respectively. These volumes are sold to private companies for the production of fertilizers and feedstock. In addition, 49,677.28 liters of wastewater are recycled daily for irrigation. The estimated costs for the best treatment are economically viable, as the expense is low compared to other conventional treatments for industrial purposes. Further research based on doses and frequencies, under different environmental conditions, is recommended.
