System and method for removing contaminants from water

   
   

A system and method for removing contaminants from water that has a relatively low oxygen content with naturally occurring chemoautotrophic bacteria, ferrous iron, manganese, sulfide, and other contaminants. The system comprises an oxygenation vessel for oxygenating the water and a filtration vessel having bio-filtration media with surfaces that are exposed to the oxygenated water. The chemoautotrophic bacteria propagate in the presence of the oxygenated water and deposit certain of the contaminants on the bio-filtration media as by-products. The contaminants are also precipitated in the presence of the oxygenated water and settle on the bio-filtration media in at least the filtration vessel. A secondary filtration stage can further remove contaminants from the water that were not sufficiently removed by the first filtration stage.

Um sistema e um método para remover os contaminadores da água que tem um índice de oxigênio relativamente baixo com as bactérias chemoautotrophic naturais, ferro ferroso, manganês, sulfide, e outros contaminadores. O sistema compreende uma embarcação do oxygenation para oxygenating a água e uma embarcação do filtration que tem meios do bio-filtration com superfícies que são expostas à água oxygenated. As bactérias chemoautotrophic propagam na presença da água oxygenated e depositam certo dos contaminadores nos meios do bio-filtration como by-products. Os contaminadores precipitated também na presença da água e do settle oxygenated nos meios do bio-filtration ao menos na embarcação do filtration. Um estágio secundário do filtration pode mais mais remover os contaminadores da água que não foram removidos suficientemente pelo primeiro estágio do filtration.
