Waste waters from paper industry
90 % of TOC (COD) is related to organic acids. After aerobic biologic treatment all acids were oxidised.
Also, other non-humic matter was oxidised and humics remain the only refractory matter after biologic treatment.
97 % TOC was destroyed. A further reduction of TOC with biologic methods is impossible.
