“…Reusing agricultural drainage water can be an ideal solution to solve irrigation water insufficiency. Due to salinity issues, reused drainage water quality is extremely important, particularly in arid regions like Egypt (Ashour et al 2021 ; Ezzat and Elkorashey 2020 ). Consequently, integrated water and wastewater management/reuse are needed urgently for sustainable practices.…”

In this work, cotton stalks (Gossypium barbadense) and date palm stones (Phoenix dactylifera) have been used as biosorbents to remove cadmium; Cd(II), lead; Pb(II), and zinc; Zn(II) from mono- and multi-solutions. Each biosorbent was characterized using SEM-EDX, and FT-IR. The findings showed that pH, dose, contact time, metal concentration, and particle size affect the treatment process. The adsorption pattern was Pb(II) > Cd(II) > Zn(II) for both biosorbents. The adsorption performance of cotton stalks was higher than that of date palm stones. The fitted maximum uptake capacities; qm of cotton stalks were higher than those of date palm stones. The maximum adsorption at optimum conditions of Pb(II), Cd(II), and Zn(II) with cotton stalks were 98%, 92.1%, and 78.9%, respectively, within 30 min. While the maximum adsorption of Pb(II), Cd(II), and Zn(II) with date palm stones were 94.6%, 76%, and 68.6%, respectively. Results confirmed the antagonistic effect of heavy metal removal at optimum conditions. Biosorbents could remove ~ 100% of the metal ions from real wastewater samples. Regeneration investigation revealed a successful reusability of both biosorbents for four cycles.

Shatt Al-Arab River in Basrah province, Iraq, was assessed by applying comprehensive pollution index (CPI) at fifteen sampling locations from 2011 to 2020, taking into consideration twelve physicochemical parameters which included pH, Tur., TDS, EC, TH, Na + , K + , Ca +2 , Mg +2 , Alk., SO 4 -2 , and Cl -. The effectiveness of multiple linear regression (MLR) and artificial neural network (ANN) for predicting comprehensive pollution index was examined in this research. In order to determine the ideal values of the predictor parameters that lead to the lowest CPI value, the genetic algorithm coupled with multiple linear regression (GA-MLR) was used. A multi-layer feed-forward neural network with backpropagation algorithm was used in this study. The optimal ANN structure utilized in this research consisted of three layers: the input layer, one hidden layer, and one output layer. The predicted equation of the comprehensive pollution index was created using the regression technique and used as an objective function of the genetic algorithm. The minimum predicted comprehensive pollution index value recommended by the GA-MLR approach was 0.3777.

“…Reclaimed water helps the whole of society with the ever-more-difficult task of meeting global water demand for irrigation whilst enhancing economic development in a sustainable way [28][29][30]. Treated wastewater also contributes positively to those crop soils irrigated with it, since this resource has proved to be an excellent fertilizer that improves soil quality due to the high quantity of essential nutrients it contains [31][32][33]. Furthermore, productivity in crops irrigated with tertiary water has been proved to be boosted by using this water source.…”

Farmers’ Attitudes towards Irrigating Crops with Reclaimed Water in the Framework of a Circular Economy

In a global situation where water constraints are a daily concern and expected to worsen in the upcoming years, finding new water alternatives to guarantee its supply is of critical importance. Against this background, reclaimed water has proved to be a sustainable alternative that recycles wastewater from a circular economy approach, thus enhancing water availability for key sectors such as agriculture. In such a context where public policies should encourage the implementation of this sustainable resource that helps reduce climate change by allowing wastewater reuse, there is too often a lack of knowledge of farmers’ perceptions, thus resulting in them being ineffective. In this sense, studying and analyzing agriculturalists’ perceptions is of interest for the development of appropriate policies that truly foster reclaimed water use in agriculture and enhance its shift from waste to resource. For this research 231 farmers, both long-time users of reclaimed water and non-users, were surveyed to find common and differing attitudes and perceptions. Results show how once farmers start irrigating their crops with this alternative resource there is a marked improvement in their opinion. The high price is the most widespread barrier, which can be tempered with public subsidies that absorb part of this cost. The insights obtained from this research may be of interest to other regions, especially for those in arid and semi-arid climates where water scarcity is a critical problem and sustainability a growing concern.
