Nitrogen removal from raw landfill leachate by an algae–bacteria consortium
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 ...
