The use of constructed wetlands for the treatment and reuse of urban wastewater for the irrigation of two warm-season turfgrass species under Mediter…

Constructed wetlands (CWs) represent low-cost technology for the treatment and reuse of wastewater in urban areas. This study aimed to evaluate the pollutant removal efficiency of a CW system and to assess the effects of irrigation using treated urban wastewater on soil and on two warm-season turf species. The research was carried out in Sicily (Italy) on a pilot-scale horizontal subsurface flow system which was fed with treated urban wastewater following secondary treatment from an activated-sludge wastewater treatment plant. The pilot system was located in an open urban park and comprised two separate parallel planted units. Experimental fields of Cynodon dactylon (L.) Pers. and Paspalum …
Wastewater management using a pilot-scale horizontal subsurface flow system in Western Sicily (Italy) for irrigation of Paspalum vaginatum Sw. turf
2017
The reuse of treated wastewater represents an attractive prospect for sustainable water management in urban areas. The aim of this study was to evaluate the reuse of treated wastewater from constructed wetland systems for the irrigation of Seashore paspalum turf (Paspalum vaginatum Sw.) and assess the effects of treated wastewater on the soil and turfgrass. The research was carried out in Sicily (Italy) in a pilot-scale horizontal subsurface flow system (HSSF). Seashore paspalum plots were irrigated with freshwater and treated wastewater. In treated wastewater-irrigated plots, we estimated the amounts of nitrogen and potassium, supplied by irrigating with treated wastewater. The productive …
Management of irrigation water and nutrient demands of tomato (Lycopersicon esculentum Mill.) using urban treated wastewater from a pilot-scale horiz…

The reuse of treated wastewater (TWW) in crop irrigation is an advanced and rational approach to water resource management in agriculture. Results would seem to demonstrate that it could be an extremely important tool in the reduction of freshwater (FW) consumption in agriculture, at the same time helping to increase crop yields through the transfer of nutrients required for crop growth. In arid and semi-arid areas of the Mediterranean, constructed wetlands can play a key role in the treatment and reuse of wastewater due to their multifunctional nature. The aim of this study was to manage water and nutrient requirements of tomato (Lycopersicon esculentum Mill.) using TWW from a pilot-scale …
