Bioremediation of Raw Landfill Leachate Using Galdieria sulphuraria: An Algal-Based System for Landfill Leachate Treatment

This study aims to evaluate the potential of using a thermophilic acidophilic red alga, Galdieria sulphuraria for effective on-site treatment municipal landfill leachate (LL). focused on evaluating effects LL dilution, nitrogen loading, and initial algal biomass density overall efficiency, evaluated long-term performance system 5-day growth cycles. confirmed that optimal conditions G. production are 20% strength LL, lower concentration 0.25 g L−1, addition N at twice level media. Furthermore, results indicated sulphuraria’s ability grow in elevated NH4-N (>950 mg L−1) provide removal rates up 40 L−1 d−1. In addition, running experiment showed proposed algal-based could be applied semi-continuous mode achieve bioremediation. Overall, obtained from this can used develop necessary process parameters implement large-scale systems treatment.
