Abstract
The sample of industrial effluent was collected from the industrial effluent discharge site to river Periyar. The test species, a blue green alga Spirulina platensis was inoculated at different concentrations of effluent such as 10%, 20% and 50%. After 10 days treatment the effluent samples were analysed for selected physiochemical characters. The growth of Spirulina platensis was measured at every two days interval for ten days. At 20% effluent concentration the maximum biomass and BOD and fluoride removal were obtained.
