Chitosan/LDH surface-modified polyurethane carriers: enhanced biofilm formation, stability, and nitritation reactor performance

Puntos clave

• Enhanced biofilm formation improved overall reactor stability and efficiency, indicating significant performance gains.
• The study found a 40% increase in biofilm density using chitosan-LDH surface modifications in the reactors.
• Assessment using surface-modified polyurethane as carriers demonstrated effective nitritation in wastewater.
• Further optimization may enable broader application of these findings in wastewater treatment systems.
