TREATMENT OF WATER CONTAMINATED BY VOLATILE ORGANIC COMPOUNDS IN HYDROPONIC ROOT MATS
Chen, Z., N. Reiche, J. Vymazal, and P. Kuschk.
Ecological Engineering 98:339-345(2017)
Scientists investigated the treatment of VOC-contaminated water in hydroponic root mats (HRMs) under pilot-scale conditions near a former industrial area in Leuna (Saxony-Anhalt, Germany). Floating hydroponic root mats (FHRM) and hydroponic root mat filter (HRMF) mesocosms were established to receive groundwater contaminated mainly with benzene and MTBE. Both systems exhibited similar MTBE removal performance during two years of operation, but seasonal variation was observed for benzene removal, with almost complete removal of benzene during summer in both systems. The floating system exhibited higher benzene removal efficiency than the filter system, especially during the second year of operation. Overall MTBE mean removal efficiency was 32% compared to 61% benzene removal. Emission rates of benzene and MTBE in the floating system accounted for 3% and 30.8% of the total benzene and MTBE removal, respectively, but only 2.3% and 8.3% in the filter system.
