“…To minimize crop loss, it is necessary to identify new irrigation management strategies, such as increased leaching, to maintain high and constant substrate humidity (Bañón et al, 2011), or to use salt-tolerant plants and develop salt-tolerant crops through breeding programmes. One solution to improving the agronomic quality of the reused water could be to blend it with well water (Chaiprapat and Sdoodee, 2007;Gori et al, 2008;Bañón et al, 2011).…”

The scarcity of water has frequently led to saline water being reused for the irrigation of ornamental shrubs. However, before the use of such waters can be expanded, the salt tolerance and other characteristics of the ornamentals involved, need to be considered along with their capacity to recover after salinity exposure. For this reason, Euonymus japonica (euonymus) and Viburnum tinus (laurustinus) plants were submitted for twenty weeks to three irrigation treatments applied at 100% water holding capacity: Control (EC < 0.9 dS m-1); NaCl solution, NaCl (EC: 4 dS m-1); and wastewater, WW (EC: 4 dS m-1). This was followed by a recovery period of eight weeks, when all the plants were watered in the control irrigation conditions. The results showed that biomass, leaf number and total leaf area of plants subjected to the saline treatments were lower than in the control at the end of both periods in both species. However, after recovery, only euonymus showed lower growth parameters than those observed in the saline period. The highest Na + and Clconcentrations were observed in saline plants at the end of saline period for both species, and were higher in shoots than in roots. The opposite was observed for the K + /Na + and the Ca 2+/ Na + ratios. In Laurustinus, the ? stem did not diminish in the wastewater-irrigated plants with respect to the control, maintaining osmotic adjustment and a high ? t , even after recovery, whereas in euonymus this did not occur at the end of recovery period. In both species the P n and g s were similarly reduced during the saline exposure period. However, the recovery of gas exchange in laurustinus irrigated with wastewater might be closely related to the better water status of these plants. Although the aesthetic value and growth decreased in the plants of both species, the chemical properties of the waters applied had different effects in each case, especially as regards the capacity to recover from salinity. These results underline the 3 importance to studying the physiological mechanisms involved in the recovery of plants.

“…Concerning industrial wastewaters, the treated effluent was suitable for the irrigation of ornamental plants but the use of drip irrigation should be suggested in order to avoid a decrease in the quality of the plants produced due to tip and edge burn of leaves. Moreover, because of the saltsensibility of numerous plants, the use of a tertiary effluent with such water quality can always be recommended for short periods (Gori et al 2008).…”

The present study is aimed at verifying the possibility of reusing municipal and industrial reclaimed wastewaters for the irrigation of container-grown ornamental shrubs, paying attention to the refinery treatment. The research has been carried out in the district of Pistoia (Central Italy), which represents one of the main nursery areas in Europe. Two experimental sites, each consisting of a refinery treatment pilot plant (filtration and disinfection) and an agronomic area, were set-up. In this paper the attention is focused on the selection of the refinery treatment. The combined process of peracetic acid (PAA) and ultraviolet irradiation (UV) chosen for the disinfection treatment proved to be very effective for the inactivation of microorganisms for both municipal and industrial wastewaters. The high efficiency is recognised as being brought about by the formation of free radicals due to the photolysis of the PAA when in the presence of the UV rays. A preliminary cost analysis has been carried out in order to highlight the most economically advantageous solution which guarantees the compliance to the Italian limits for wastewater reuse in agriculture (Escherichia Coli 10 CFU/100 mL).

“…For this, determination of the organic load in the studied wastewaters was performed through calculation of BOD5 and COD. Gori et al (2008) [46] conducted experiments to verify the possibility of reusing industrial wastewater of comparable quality to that used in this study (originated from textile (70%) and domestic (30%) activities) for the irrigation of ornamental shrubs. They found that some of them (Buxus and Pistacia) showed no signs of toxicity, while others (Viburnum and Photinia) showed greater sensitivity especially during sprinkle irrigation.…”
