Desalination of effluent waste using biomass heat in pyramid still
A Senthil Rajan, C Ramji, A Allaudeen
In this work a pyramid solar still is, used to produce distilled water from industrial effluent using biomass heat source, solar energy. Since industrial waste is utilized as feed primary treatment is given to filter the waste. The concept of integrating the single basin still with biomass heat source is introduced in this research study. At the bottom surface of the basin, heat exchanger is laid at the bottom end. The heat exchanger is connected to the biomass boiler increases the water temperature in the still. A conventional still is also tested with the modified still for comparison. Different solid heat storage materials, Latent heat storage materials are introduced in the shape of small billets to increase productivity. Glass cover cooling is performed by using manual sprinkler at regular interval of fourth dimension. Biomass are tried in this workplace. Chemical analysis shows the reduction of 99% of salts and 100% TDS and 100% increase in COD, BOD levels in the distilled water. Experiments were conducted in biomass modes. Pyramid still produces more output than conventional still.
