“…The removal rates of these mesocosm systems are very similar to full-scale ICW treating agricultural wastewaters (Scholz et al, 2007;Mustafa et al, 2009;Harrington & McInnes, 2009) as shown in Table 3. The initial concentration reductions dropped rapidly due to overloading and potentially greater throughflow due to rainfall.…”

“…Percentage removal rates in the mesocosm systems for ammonia-N and MRP were 99.3 and 97.8%, respectively. Previous studies on ICW systems treating dairy wastewaters have shown ammonia-N and MRP removal rates of 99 and 91.8% removal, respectively (Mustafa et al, 2009). Concentration reductions as well as specific inflow and outflow concentrations are shown in Table 2.…”

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

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.

“…Plant and sediment samples were collected from the first cell of the ICW 11, where the major contaminant removal is likely to take place (Mustafa et al 2009). This wetland is located in County Waterford (southeast of Ireland), at a longitude of 07º02′40″ W and a latitude of 52º11′28″ N. The ICW system was constructed in 2000, and commissioned in February 2001 to contribute to the improvement of the water quality of the Annestown Stream.…”

This paper investigates the role of plants and sediment in removing nutrients from wastewater being treated in a representative integrated constructed wetland (ICW). It discusses the role of plants and sediment in removing nutrients from an ICW treating agricultural wastewater for more than 7 years. More nitrogen and phosphorus were stored in wetland soils and sediments than in plants. The first cell had the highest depth of sediment accumulation (45 cm). Over the 7-year operation period, the accretion rate was approximately 6.4 cm/year. With respect to maintenance, desludging of the first wetland cell of the ICW system appears to be necessary in 2011. An average of 10,000 m 3 per year of wastewater entered the ICW. Approximately 74% (780 kg) of the phosphorus and 52% (5,175 kg) of the nitrogen that entered the wetland system was stored in the wetland soils and sediments. Plants stored a small fraction of nutrients compared to soils (<1% for both nitrogen and phosphorus). This study demonstrates that soils within a mature wetland system are an important and sustainable nutrient storage component.

Other reported rates of EC or FC attenuation in CFWs range from 1.61-3.56 log 10 (excluding the site in SE Scotland where reports an increase in FC due to faecal inputs from wild birds), and Knox, Tate et al (2007) report lower rates of EC attenuation at higher flow rates in irrigated beef cattle pasture in California.…”

The excreta (faeces and urine) of mammals and birds are widespread across planet Earth and frequently contaminate water that is used for bathing and recreation, that is treated and distributed for human consumption, and that is used to irrigate crops.The risk that such contamination represents to human health is inadequately understood. It is widely assumed that faeces of animals represents a lesser risk to human health than human faeces of because of the 'species barrier' and especially the species-specificity of most viruses. This book points to a rational and systematic way of assessing the risks and to cost-effective approaches to manage them. The information presented is expected to have important consequences for prioritisation of preventive and remedial interventions.
