Manganese recovery and ammonia nitrogen removal from simulation wastewater by pulse electrolysis
Highlights
•
PC electrolysis was developed to recover manganese and remove ammonia nitrogen.
•
Manganese could be reduced from 160 mg L−1 to 0.2 mg L−1 for 2.5 h.
•
Ammonia nitrogen could be removed from 80 mg L−1 to 0.1 mg L−1 for 2.5 h.
•
Manganese was mainly recovered in the form of manganese dioxide.
