Ruiz, M. Soto] A comparative long-term study of three subsurface horizontal-flow (HF) constructed wetlands (CW) treating winery wastewater was carried out. The water depth for HF1 was 0.3m, while the depth for HF2 and HF3 was 0.6m, respectively. Hydraulic loading rate ranged from 7 to 93mm/d, while surface loading rates fell into the following ranges: 4-85g COD/m2·d, 2-49g BOD5/m2·d and 0.5-6g TSS/m2·d. The percentage of biological oxygen demand (BOD5) removal clearly decreased when influent concentration increased, while surface removal rate increased and reached a maximum of approximately 8g BOD5/m2·d removed in the range of 10-20g BOD5/m2·d fed, depending on the CW depth. HF1 showed a worse performance than the other units, appearing to be more affected by high influent concentrations. Solids accumulation on gravel media, hydraulic conductivity and gas emissions were monitored over the 2.8years of operation.
