Abstract

This waste-to-profit study evaluated the recycling of treated effluent as a source of dilution water for the cultivation of Scenedesmus sp. in anaerobically digested abattoir effluent (ADAE) under outdoor conditions over 3 months. Despite biomass productivity of Scenedesmus sp. trending lower for ADAE grown cultures diluted with recycled wastewater (RWW) than freshwater (FW) at the beginning (Week 2–8), RWW grown cultures subsequently recovered and showed significantly higher productivity (28–55 %) during the remaining study (Week 10–15). A similar outcome was also observed for the photo-physiology and ammonia removal rates of Scenedesmus sp. in both treatments. Weekly ammoniacal nitrogen removal efficiency ranged between 70 and 100 % for FW and 38–98 % for RWW. Although bacterial load, the concentration of dissolved & suspended solid, total organic carbon and trace metals was higher in the RWW culture than the FW, no negative effect was seen on the growth and bioremediation capacity of Scenedesmus sp.. Overall, this study clearly demonstrated the recycling of treated wastewater to be efficient for treating ADAE using Scenedesmus.
