Resumo

Os coagulantes naturais são compostos naturais, como sementes, mucilagem e outros compostos baseados ou não baseados em plantas, que possuem a capacidade de remoção de contaminantes da água, esgotos e efluentes. Seu uso possui forte apelo ambiental, econômico e social, especialmente por se tratarem de compostos facilmente encontrados na natureza, como a moringa, quiabo e cáctus, e, por isso, baratos, aumentando a qualidade de vida da sociedade e mitigando o dano ou impacto ambiental. Esta revisão teve por objetivo apresentar os diferentes tipos de coagulantes naturais, seus respectivos usos e características. Esta pesquisa foi elaborada por meio de consultas na literatura especializada, com cerca de 160 artigos pesquisados e 38 efetivamente utilizados; concentrou-se em discutir os benefícios dos coagulantes naturais frente aos coagulantes químicos, bem como as implicações dos diferentes tipos de coagulantes naturais no tratamento de água, efluentes líquidos e esgotos. Em suma, verificou-se que as questões que envolvem a pesquisa dos coagulantes naturais é um caminho ambientalmente correto, barato e um objetivo a ser alcançado, visto a grande demanda de tratamento de água e efluentes que ocorre ao redor do mundo.
