“…The optimal level of N-fertilizer application is dependent on the depth of irrigation water. The impact of exposure to excess irrigation water and N-fertilizer can be very significant not only in reducing plant yield but also in deteriorating surface water quality [39]. Abbasi et al [40] investigated the effects of furrow fertigation management on nitrate losses through surface runoff in a cornfield and stated that the nitrate losses have ranged between 5.7 and 42.0%.…”

The purpose of this study was to evaluate the effects of furrow fertigation on nitrate deep leaching, nitrate runoff losses, and plant nitrogen supply in various growth stages of maize (Zea mays L.). Furrow fertigation experiment was conducted in 120 (W1), 100 (W2), 80 (W3), and 60% (W4) levels of required water (560 mm) and 100 (N1), 80 (N2), 60 (N3), and 0% (N4) levels of required nitrogen fertilizer (184 kg N ha−1). N-fertilizer was applied in four split applications (before planting, at the seven-leaf, shooting, and flowering). In the farmers’ conventional fertilization (FCF) method, 120% level of required water and 100% level of the required N-fertilizer were used in two split applications (before planting and at the seven-leaf stage). Results showed that the highest maize aboveground nitrogen content was 3.11% for FCF treatments at the seven-leaf stage. The maximum nitrogen content in the sensitive flowering stage and the maximum grain yield were also observed in W2N1 treatment with 2.27% and 12.93 ton ha−1, respectively. While, there were no significant differences in aboveground nitrogen content and grain yield between W2N1 and W3N1, W2N2, and W3N2. The highest amounts of nitrate leaching out of the 80-cm soil layer and nitrate runoff losses, were also recorded in FCF treatment, followed by W1N1, W2N1, and W3N1. Based on plant nitrogen content, nitrate losses and maize yield, 80% levels of the required N-fertilizer and required irrigation water could be recommended as the optimal levels to reduce nitrate losses and improve maize yield.

“…This may be due to the high salinity of sewage irrigation water, resulting in the accumulation of topsoil in farmland (Angin, Yaganoglu et al 2005). This will bring adverse consequences, such as soil compaction and fertility decline, as well as adverse effects, such as crops are di cult to absorb nutrients, hindering crop growth (Chojnacka, Witek-Krowiak et al 2020).…”

The activity of heavy metals in farmland soil and the safety of food crops after long-term sewage irrigation are the premise of sustainable development of agriculture. The major pollutants of arsenic (As) and cadmium (Cd) in farmland-corn system affected by sewage irrigation for 40 years were studied. The results showed that although the content of total As in soil was high, the absorption and transport of total As by corn were relatively small, and As could not migrate down the soil profile. On the contrary, Cd mainly exists in the form of exchangeable and carbonate-bound which has strong fluidity. By optimizing the method of investigating the bioavailability of pollutants and systematically and comprehensively studying the migration law of pollutants in various parts of maize tissues, it is concluded that Cd still has high activity after stopping sewage irrigation, and the development process of maize roots has a significant relationship between the contact of heavy metals in the surface soil and the enrichment of heavy metals in the upper part of corn tissues (p < 0.01). Therefore, this study can increase the understanding of the migration law of pollutants in corn, and provide a basis for remediation of contaminated soil in local and other areas.

“…Domestic wastewater is characterized by a high concentration of nutrients (N, P, K, Ca and Mg) and by high bacterial loads, such as pathogenic bacteria, viruses, common protozoa (Giardia and Cryptosporidium) and helminths, which can pose a direct threat to human health. Therefore, given the epidemiological health hazard, eliminating pathogens is one of the objectives of wastewater treatment systems [5]. In addition, these urban wastewaters can also contain contaminants of emerging concern (CECs).…”

“…For compliance and obtaining an effluent that meets the legal requirements for subsequent reuse in agriculture [5], different conventional and advanced physical and biological treatment options have been investigated for eliminating pathogenic microorganisms and CECs [19]. Table 1 shows the treatments that have performed best for eliminating CECs as well as other pathogens based on the use of physical, biological or chemical treatments.…”

Water Reuse Study from Urban WWTPs via c-Ultrafiltration and Ozonation Technologies: Basis for Resilient Cities and Agriculture

et al. 2021

The water–development nexus is essential for the advancement and progress of cities in the face of problems such as climate change, water security and increasing environmental stress in the agricultural sector. Aiming for a circular economy and, at the same time, improving the resilience of water supply alternatives and achieving a goal of zero waste, this work presents a technical–economic study of a novel continuous ultrafiltration (c-UF) system with self-cleaning capacity coupled to an ozonation process, for the treatment of urban WWTP effluent. The removal efficiencies achieved were analysed both through macroscopic parameters (suspended solids, turbidity) and for the most frequently occurring contaminants of emerging concern (CECs). Consequently, an effluent suitable for irrigation was obtained, with a total recovery factor of 97.92%, a concentration of suspended solids (SS) below 1 mg L−1, 0.06 NTU turbidity and toxicity free, complying with the new European Regulation on Water Reuse (EU 2020/741). A comparative analysis of the proposed process with regard to conventional tertiary treatment revealed that the proposed process was 39.1% more economic, with a cost of 0.0325 € m−3. This alternative treatment will be of great interest because of its favourable technical–economic characteristics, being postulated as a basic process for implementation in modern water reuse plants.
