Sažetak
Three samples of terra rossa were good adsorbents of phosphate (P(V)) from wastewater and removed 29.9-32.6% of P(V). The total iron content in terra rossa was the key factor which determined the P(V) removal from wastewater. The original samples of terra rossa were good support materials for the immobilization of metabolically active P(V)-accumulating bacteria Acinetobacter junii (0.56-2.47 x 1010 CFU g-1). The removal of oxalate extractable iron from original sample of terra rossa increased the number of immobilized bacteria to 1.34 x 1011 CFU g-1, which is the highest number of immobilized bacteria reported in the literature so far. In reactors containing the A. junii and terra rossa P(V) was removed from wastewater by simultaneous adsorption onto terra rossa and accumulation inside bacterial cells, resulting in the 40.5-62.5% of P(V) removal. Terra rossa is the promising substrate for the process of biological P(V) removal from wastewater, where it can have dual function: as the adsorbents of P(V) and carrier of P(V)-accumulating bacteria.
