“…In recent years, the use of constructed wetlands (CWs) for the treatment of agricultural wastewaters, including those produced by food-processing industries and by livestock farms, has been gaining popularity due to their relatively low construction costs and maintenance requirements (Cronk, 1996;Knight et al, 2000;Del Bubba et al, 2004;Carty et al, 2008;Harrington and McInnes, 2009;Yalcuk et al, 2010;Herouvim et al, 2011;Yalcuk, 2011;Harrington et al, 2012;Kapellakis et al, 2012;Justino et al, 2012). Their use as buffer zones to provide effective protection of water bodies from agricultural runoff events, namely for the containment of associated pesticide contamination hazards, has also been studied and applied (Gregoire et al, 2009;Warsaw et al, 2012;Matamoros et al, 2012b).…”

H I G H L I G H T S• CW with LECA substrate and Phragmites plants tested with agricultural wastewaters.• High removals of TSS, COD, NH 4 -N, polyphenols, a pharmaceutical and a pesticide.• Contact time of wastewaters with beds ranged from 3 to 9days in batch conditions.• Promising results suggest more studies in full-scale and more realistic conditions. Constructed wetlands (CWs) are receiving a renewed attention as a viable phytotechnology for treating agricultural wastewaters and for the removal of more specific pollutants, in particular recalcitrant ones. In this work, the performance of CW mesocosms using light expanded clay aggregates (LECA) as the bed's substrate and planted with Phragmites australis was investigated for treatment of olive mill wastewater (OMW), swine wastewater (SW) contaminated with oxytetracycline and water contaminated with herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid). Both wastewaters (OMW and SW) initially presented high organic matter content and total suspended solids which were removed by the system with efficiencies higher than 80%. Removal of polyphenols in OMW and nitrogen compounds in SW also showed similar or higher efficiencies in comparison with other treatment systems reported in the literature. The antibiotic oxytetracycline was completely removed from SW within the assay period in unplanted LECA beds, but planted beds allowed a significantly faster removal. In regard to water contaminated with MCPA, the results showed that LECA has a large sorption capacity for this herbicide (removal efficiencies of 56-97%). In general, considerably higher pollutant removal efficiencies were obtained when plants were used (up to 28% higher). The results obtained are indicative that CWs with LECA as substrate may be an adequate option for agricultural wastewater treatment. a b s t r a c t a r t i c l e i n f o

“…This presents the landowner with a considerable problem where spreadlands are limited or already over-loaded. Constructed wetlands, such as integrated constructed wetlands (ICW), pioneered in Ireland, offer an efficient and environmentally beneficial approach to the treatment of wastewaters such as these (Harrington & Ryder, 2002;Harrington et al, 2005;Dunne et al, 2005;Scholz et al, 2007;Babatunde et al, 2008;Harrington & McInnes, 2009). ICW systems are surface-flow constructed wetlands that treat wastewaters through means of natural processes including: sedimentation, mineralisation, plant and microbial uptake, denitrification, nitrification and atmospheric releases.…”

The use of integrated constructed wetlands (ICW) for the treatment of separated swine wastewaters

et al. 2011

The use of constructed wetlands for the treatment of wastewater is an approach that has received increasing attention over the last 30 years due to their innate ability to deal with a wide range of highly variable influent types. The treatment of swine wastewater is an on-going issue due to its generally higher nutrient concentrations and the limited land available to owners. The implementation of the European Union Nitrates Directive and Water Framework Directive is currently placing considerable pressure on agriculture in EU member states with its focus on the improvement and sustained quality of surface waters. The limit of 170 kg of organic nitrogen/ha/annum imposed by the Nitrates Directive can cause severe difficulties for wastewater management in the piggery industry in Ireland, where spreadlands are already receiving high application rates of organic N. A replicated mesocosm integrated constructed wetland (ICW) approach was examined for the effective treatment of anaerobically digested separated swine wastewater with emphasis on nutrient removal. These mesocosm systems are based on operations identified in the available literature as well as on the ICW Concept pioneered in Ireland. The removal efficiency yielded substantial results over an 18 month period and highlighted high mass removal of ammonia-nitrogen (98.1-99.9%) from the influent. The removal recorded in all operational replicates throughout the study period showed that wetlands based on the ICW concept may very well prove to be a viable and sustainable approach for the treatment of swine wastewaters in Ireland whilst successfully addressing both the Nitrates and Water Framework Directives.
