“…These three heavy metals should be of more concern during the long-term reclaimed water irrigation. Soil heavy metals were mainly accumulated in the soil top layer (Brar et al 2002), and downward leaching of heavy metals was little (de Miguel et al 2013). However, the heavy metal input through reclaimed water irrigation was small, and soil heavy metal contents in all plots did not exceed the national standards.…”

“…However, there are the risks of nutrient imbalances and groundwater contamination of nitrate with irrational managements of reclaimed water (Candela et al 2007). Due to its relative high-level salts compared to tap water, reclaimed water irrigation has led to soil property deterioration and affected plant growth (de Miguel et al 2013;Pedrero et al 2014). Accumulations of toxic substances such heavy metals and musk in soils receiving reclaimed water sometimes are also noticed (Chen et al 2013a;Kang et al 2007;Wang et al 2013).…”

Reclaimed water is widely used for landscape irrigation with the benefits of saving fresh water and ameliorating soil quality. Field samples were collected from seven parks in Beijing irrigated reclaimed water with different irrigation history in 2011 and 2014 to evaluate the long-term impacts of reclaimed water irrigation on soil quality. Soil quality index method was used to assess the comprehensive effects of reclaimed water irrigation on soil. Results showed that the effects of reclaimed water irrigation on the soil nutrient conditions were limited. Compared with tap water irrigation, soil salinity was significantly higher in 2011, while the difference was insignificant in 2014; soil heavy metals were slightly higher by 0.5-10.6 % in 2011 and 2014, while the differences were insignificant. Under reclaimed water irrigation, soil biological activities were significantly improved in both years. Total nitrogen in reclaimed water had a largest effect on soil quality irrigated reclaimed water. Soil quality irrigated with reclaimed water increased by 2.6 and 6.8 % respectively in 2011 and 2014, while the increases were insignificant. Soil quality of almost half samples was more than or closed to soil quality of natural forest in Beijing. Soil quality was ameliorated at some extent with long-term reclaimed water irrigation.

“…Moreover, the ground tezontle rock used as the media in the CWs has demonstrated a high capacity for total dissolved solid removal in previous studies [42]. The final values in the three effluents averaged less than 1.5 dS/m, which is considered as the threshold value from which a reduction in crop yield potential due to salinity, can be expected in salt-sensitive species [43,44]. …”

In this study, three different two-stage hybrid ecological wastewater treatment systems (HEWTS) with combinations of horizontal flow (HF) constructed wetlands (CWs), vertical flow (VF) CWs and stabilization ponds (SP) were evaluated for the removal of Organic-N, NH 4 + , NO 3 − , Total N, Total P, Total Coliforms (TCol) and Escherichia Coli, BOD, COD and TSS. The overall goal of the study was novel in comparison to most other studies in that we sought to evaluate and compare the efficiency of the three HEWTSs for water quality improvements, while minimizing nutrient removal from the wastewater in order to generate high quality reclaimed water for reuse for irrigation of crops. The most effective systems were those systems containing a vertical flow component, either HF-VF or VF-HF. In these two HEWTS, NH 4 + was reduced by 85.5% and 85.0% respectively, while NO 3 − was increased to 91.4 ± 17.6 mg/L and to 82.5 ± 17.2 mg/L, respectively, an artifact of nitrification. At the same time, E. coli was reduced by 99.93% and 99.99%, respectively. While the goal of most wastewater treatment is focused on reducing nutrients, the results here demonstrate that two-stage HEWTSs containing VF components can be used to produce a high quality effluent while retaining inorganic nutrients, thereby conserving this valuable resource for reuse as irrigation water for agriculture in subtropical developing countries where water and fertilizer resources are scarce or expensive.

“…They concluded that the irrigation with RWW needs to consider both the water requirements of the crop and irrigation doses needed for controlling salinity build-up in the top soil in arid climates. In Carrión de los Céspedes, Spain, De Miguel et al [17] found no significant differences in biomass production and the nutrient content of JCL leaves based on irrigation water quality (groundwater vs. reclaimed water). Although without offering production data, they conclude that using RWW for JCL irrigation could ease the pressure on water resources and represent an alternative source of clean energy.…”

Abstract:In a global context in which obtaining new energy sources is of paramount importance, the production of biodiesel from plant crops is a potentially viable alternative to the use of fossil fuels. Among the species used to produce the raw material for biodiesel, Jatropha curcas L. (JCL) has enjoyed increased popularity in recent years, due partly to its ability to grow in degraded zones and under arid and semi-arid conditions. The present study evaluates the potential for JCL production under irrigation with non-conventional water resources in abandoned agricultural soils of the island of Fuerteventura (Canary Islands, Spain), which is one of the most arid parts of the European Union. JCL growth and productivity are compared during the first 39 months of cultivation in two soil types (clay-loam and sandy-loam) and with two irrigation water qualities: recycled urban wastewater (RWW) and desalinated brackish water (DBW). The results indicate that JCL growth (in terms of plant height and stem diameter) was significantly influenced both by soil type and water quality, with better development observed in the sandy-loam soil under RWW irrigation. Productivity, measured as cumulative seed production, was not affected by soil type but was affected by water quality. Production under RWW irrigation was approximately seven times greater than with DBW (mean ~2142 vs. 322 kg·ha 6903 were found to be key factors in the greater productivity observed under irrigation with this type of water.
