Fosfat-akumulirajuće bakterije primjenjuju se u procesu poboljšanog biološkog uklanjanja fosfata iz otpadne vode. Imobilizacijom fosfat-akumulirajućih bakterija na prirodne nosače postiže se veća koncentracija, a time i uspješnije uklanjanje fosfata iz otpadnih voda. Cilj ovog istraživanja bio je utvrditi sposobnost fosfat-akumulirajuće bakterije Acinetobacter junii i mineralnog nosača crvenice za uklanjanje fosfata iz otpadne vode. Korištena su četiri različita uzorka crvenice. Crvenica je pokazala relativno veliki postotak uklanjanja fosfata (25,7 -31,1 %), a u kombinaciji s fosfat-akumulirajućim bakterijama A. junii taj postotak je dvostruko veći (50,0 – 55,6 %). Phosphate-accumulating bacteria have their use in the process of enhanced biological phosphorus removal from wastewater. The immobilization of phosphate-accumulating bacteria on mineral carriers leads to a higher concentration that enables a more effective phosphate removal from wastewater. The aim of this study was to determine the ability of phosphate-accumulating bacteria Acinetobacter junii and mineral carrier to remove phosphate from wastewater. Four different samples of red soil were used. Red soil showed a relatively high percentage of phosphate removal (25,7-31,1 %), in combination with a phosphateaccumulating bacteria A. junii this percentage is two times higher (50,0 – 55,6 %). |
