“…Biodegradation may occur naturally in aquatic environment, as referred above, or may be promoted and applied to formalin removal from water. Biodegradation experiments were also performed by other authors (Lotfy & Rashed ) with a wastewater sample containing formaldehyde ranging from 31.5 to 125 mg L −1 . They observed that the inhibition effect of formalin increased with the increase in formalin concentration.…”

Formalin (aqueous solution of formaldehyde stabilized with methanol) is one of the most used disinfectants in aquaculture. It is used to eliminate infectious agents but may be responsible for negative effects on fish and water quality. This work focuses on physical–chemical properties of formalin and on its reactions and its use in intensive aquaculture and in environment. The types of treatments and the action mode of formalin are also described. The main consequences of formalin exposure to fish are damage in gills and alterations in mucous cells. Formalin also interacts with some treatments adopted in aquaculture establishments, for example biological filter, where the nitrification process seems to be strongly affected. With respect to formalin inactivation, formaldehyde (effluent) may be diluted with water or specific treatments should be conducted to decrease the concentration levels before its discharge into the environment. The common methodologies applied to aquaculture are not completely efficient on formalin removal from water, and the advanced oxidation processes may be a good alternative.

“…This compound is widely used due to its high reactivity, colorless nature, stability, purity in commercial form and low cost [1]. Relatively high formaldehyde concentrations can be present in wastewater, which contains 0.2-4.0 g/L of formaldehyde from industrial production of adhesives [2].…”

“…A Agência de Proteção Ambiental dos Estados Unidos o classifica como um "provável causador de carcinogê-nese humana". As águas residuárias que podem conter uma quantidade de formaldeído significativa comprometem o tratamento biológico, por possuir caráter inibitório dos processos biológicos de tratamento (LOTFY & RASHED, 2002). Mesmo em baixas concentrações, bacté-rias aeróbias tem seu crescimento inibido (QU & BHATTACHARYA, DOI: 10.1590/S1413-41522015020000129576 1997LU & HEGEMANN, 1998;GONZALEZ-GIL et al, 2002;LOTFY & RASHED, 2002;CAMPOS et al, 2003, entre outros).…”

O formaldeído é geralmente encontrado em águas residuárias em concentrações de até 10.000 mg.L -1 , porém já a 5 mg.L -1 apresenta toxicidade a diversos tipos de organismos (GONZALEZ-GIL et al, 2002).…”

RESUMOO estudo visou a investigação da degradação de formaldeído em um sistema combinado anaeróbio-aeróbio, de fluxo ascendente e com biomassa imobilizada, constituindo-se por um filtro anaeróbio seguido de biofiltro aerado submerso. INTRODUÇÃOO formaldeído é usado como matéria prima em muitas indústrias e utilizado também como desinfetante na área da saúde. Devido a sua toxicidade, métodos químicos ou biológicos (como os processos anaeróbios) são empregados para o tratamento de água residuárias que o contém.As atividades industriais utilizam o formaldeído como principal componente para a produção de resinas sintéticas, produtos de papel, processamento de madeira, tintas, fármacos e produtos de beleza. Além disso, ocorre naturalmente no ambiente, sendo produzido em pequenas quantidades pela maioria dos organismos vivos como parte de processos metabólicos normais (ZOUTBERG & BEEN, 1997; ATSDR, 1999;MOUSSAVI et al., 2009
