Anaerobic digestion is considered an environmentally friendly approach as it converts organic waste into valuable resources such as biogas and organic fertilizers while reducing solid waste. This study enhanced methane production from aquaculture sludge under different operating parameters: temperature (30 °C, 35 °C), S/I ratio (0.5, 1.0), and iron supplement concentration (6 g/L, 10 g/L). The biomethane potential test was con...
