文摘

Concept for simultaneous recovery of energy and nitrogen from sewage was proposed. Membrane-based preconcentration (MPC) was combined with ion exchange (IE) process. COD was recovered by MPC to achieve energy recovery. Presentation of hard ions (Ca2+ & Mg2+) decreased NH4-N IE recovery efficiency.
