Comparison of Scale in a Photosynthetic Reactor System for Algal Remediation of Wastewater Kaitlyn D. Sniffen1, Christopher M. Sales1, Mira S. Olson1 1Civil, Architectural, and Environmental Engineering, Drexel University An experimental methodology is presented to compare the performance of small (100 L) and large (1,000 L) scale reactors designed for algae remediation of landfill wastewater. System characteristics, including surface area to volume ratio, retention time, biomass density, and wastewater feed concentrations, can be adjusted based on application.

Nitrogen Removal from Raw Landfill Leachate by an Algae-bacteria Consortium Water Science and Technology : a Journal of the International Association on Water Pollution Research. 2016 | Pubmed ID: 26877028 A remediation system for the removal of nitrogen from landfill leachate by a mixed algae-bacteria culture was investigated. This system was designed to treat leachate with minimal inputs and maintenance requirements, and was operated as an open semi-batch reactor in an urban greenhouse. The results of this study showed a maximum nitrogen removal rate of 9.18 mg N/(L·day) and maximum biomass density of 480 mg biomass/L. The ammonia removal rates of this culture increased with increasing initial ammonia concentration; maximum nitrogen removal occurred at an ammonia concentration of 80 mg N-NH3/L. At starting ammonia concentrations above 80 mg N-NH3/L a reduction in nitrogen removal was seen; this inhibition is hypothesized to be caused by ammonia toxicity. This inhibiting concentration is considerably higher than that of many other published studies.
