Summary
Pereddikesyre og brintoverilte kan anvendes til vandrensning og kontrol af vandkvalitet i akvakultur systemer. Her beskrives seneste praktisake erfaringer som alternativ til f. eks. formalin.
De nye desinficerende midler er mildere og kan håndteres på en væsentlig mere sikker måde end formalin. Da begge produkter nedbrydes hurtigt, omsættes en stor del af den tilsatte mængde direkte i dammene. Ved nedbrydningen frigives ilt fra brintoverilte, mens pereddikesyre nedbrydes til vand og kuldioxid. Der udledes således mindre mængder af de to stoffer til vandløbet, og da de effektive behandlingskoncentrationer i forvejen er lave, er miljøpåvirkningen minimal.
Summary translation
Peracetic acids and hydrogen peroxide can be used as sanitizers to control water quality in aquaculture systems.
The new disinfectants are more gentle and can be managed significantly more safe than formaldehyde. As both products have a fast degradation rate, the main part of the substances remains in the fish ponds. During degradation oxygen is set free from hydrogen peroxide, while peracetic acid is degraded to water and carbon dioxide. Less of the two substances are discharged to the water course, and as the efficient treatment concentrations are low, the environmental impact is minimum.
