Effluent treatment analysis using solar distiller

Abstract

An attempt is made to treat Industrial effluent using concentrated solar distiller with latent heat storage materials. Paraffin wax is used as latent heat storage material in the basin. For further augmentation of the yield by using sponges, pebbles and Mild steel billets are added to the distiller. Daily efficiency and percentage increase in productivity for these modifications are also studied. Industrial effluent water is used as feed. To settle the industrial effluent, a settling tank was also fabricated with five layers namely: tray for raw effluent, pebble layer, coal layer, sand layer and collection tray for settled effluent. Physical and chemical analyses were made for raw effluent, settled effluent and distilled water.
