Associação de Moringa oleífera e PAC no tratamento do efluente do processo de parboilização

Abstract

To reduce the environmental impacts of industrial activities, it is It is essential to adopt sustainable practices, such as replacing synthetic coagulants by natural coagulants in the treatment of effluents. This strategy promotes a more biodegradable and less toxic treatment, reducing environmental pollution, minimizing risks to human health and aquatic life. In this study, the coagulant natural Moringa oleifera (MO) was associated with Aluminum Polychloride (PAC) for the treatment of effluent from the rice parboiling process. The MO:PAC association does not brought significant advantages and, in this scenario, opting for a 100% natural treatment is the more sustainable and simplified alternative. Treatment with 100% MO did not change the pH of the effluent and achieved efficiency in removing turbidity and organic matter, with a difference percentage of 7% and 28.8% in relation to 100% PAC, respectively. This article may assist researchers and professionals in the industry, especially food, to carry out and propose wastewater treatments in a more sustainable way.
