Formalin wastewater containing high concentrations of formaldehyde and TOC was treated and detoxified with biological aerated filter (BAF) and wetland reactors. At similar formaldehyde loading rates (about 0.01-0.9 kg/m3 d) both reactors provided high efficiencies but the BAF was more efficient at t...
