Chromium (III) and (VI), as well as phosphorus uptake from aqueous solutions by viable Spirulina, a prokaryotic algae, was tested under laboratory conditions as a function of time and initial chromium and phosphorus concentration. Effluent treatment efficiency of effluents containing chromium and phosphorus was evaluated and the results were compared with parameters given by law standards. Heavy metals removal by Spirulina spp. occurs on highly developed surface area and metal transport into the cell interior as well as by metabolic activity. A feature supporting wastewater treatment is the ability of organic compounds degradation and phosphorus, as well as nitrogen compounds removal. Chemical and thermal biomass analysis shows a real basis for Spirulina ash, containing up to 25% of chromium application in chromium compounds production process. Laboratory results show that Spirulina biomass provides enough energy for the process to be cost satisfactory. The paper is an approach toward Spirulina involved industrial wastewater treatment technology.
