Abstract
This study evaluated the unique features of a filamentous algae matrix (FAM) that can be applied to high rate algal ponds (HRAPs) as a promising way to remove nutrient from polluted rural streams. The results show that the HRAPs, coupled with the FAM, effectively removed nitrogen and phosphorus (79.8% and 81.2%, respectively), and achieved high production of DO, with a maximum of 11.0â¯g O2 g FAMâ1 dâ1. The FAM functioned wells as a screen to prevent excessive algae loss from the system and obtained relatively high biomass growth rate (0.032â¯mgâ¯Lâ1 dâ1 for nitrogen and 0.344â¯mgâ¯Lâ1 dâ1 for phosphorus). The harvested FAM was a useful fertilizer and the rate of addition of FAM were 1.52â¯kgâ¯dâ1 haâ1 of nitrogen and 0.44â¯kgâ¯dâ1 haâ1 of phosphorus. Thus, combining the HRAP with the FAM was an effective nutrient removal and resource utilization system for rural streams.
