Oxidação de cianobactérias e seus metabólitos em sistemas de tratamento de água: o estado da arte

Abstract: Eng Sanit Ambient | v.22 n.5 | set/out 2017 | 829-840 RESUMOO problema causado pelas florações de cianobactérias em mananciais para abastecimento humano vem se tornando cada dia mais preocupante não só em regiões tropicais mas em todo o mundo. Os gestores dos sistemas de tratamento de água, muitas vezes, têm que recorrer ao uso da pré-oxidação como forma de auxiliar no tratamento apesar do incremento do potencial de liberação de metabólitos e da formação de subprodutos tóxicos. Por isso, a pré-oxidação tem sid… Show more

“…Chlorine oxidation allows the degradation of dissolved CYN [21,22]; however, according to review studies of Merel et al, [23], it was identified that the use of chlorine in the oxidation of CYN caused the formation of two by-products whose toxicity should be studied. In this sense, technologies that allow the removal of dissolved cyanotoxin and that do not cause the formation of by-products are necessary in water treatment plants whose supply sources present occurrences of CYN-producing cyanobacterial blooms.…”
