Abstract: Phycoremediation is the process of removal of pollutants from waste water by using algae. Since algal culture is easily to grow, adapt and manipulate within the laboratory it can be used for remediation studies. Micro algae offer a low cost and effective approach to remove excess nutrients and other contaminants in biological waste water treatment. The present investigation was carried out to determine the bioremediation potential and bio mass production of <em>Spirulina platensis</em> using Distillery effluent. The studies showed that the maximum removal of colour, temperature (30⁰c), pH (7.5), electrical conductivity (1.13 dSm^-1), total dissolved solids (400mgL-¹), COD (450mgL^-1), BOD (280mgL^-1), manganese (1.05mgL^-1), potassium (56.23mgL^-1) was recorded after 60 days of bioremediation experiments using <em>Spirulina platensis. </em>The parameters like dry weight, growth rate, lipid and protein content also measured. The study clearly indicated the effectiveness of micro algae for the removal of nutrients present in the distillery effluent and dry biomass obtained can be used as a feed for animals.
