Removal of cadmium, chromium and lead from filamentous alga of Pithophora sp. of industrial wastewater

Bioaccumulation is the effective method for removal of heavy metal ions from wastewaters. Bioremediation, the use of algal to extract, sequester and or detoxify heavy metals and other pollutants. This technique may offer a cost- effective, less invasive and potentially more effective means of addressing existing heavy metal contamination than those currently practiced. Bioaccumulation potential of a filamentous algae Pithophora spswas compared for cadmium, chromium and lead removal at various concentrations (2ppm, 5ppm, 10ppm, 20ppm and 30ppm). The metal uptake increased with increase incubation period.
