“…This sensitivity to clogging is mainly affected by the dripper's characteristics and the water's quality, which are related to physical, chemical, and biological aspects [7,13,14]. Several authors have studied this problem, such as Abou-Shady et al [15], Baeza and Contreras [16], Coelho et al [17], and Lv et al [18].…”

Several factors contribute to the increase in irrigation demand: population growth, demand for higher value-added products, and the impacts of climate change, among others. High-quality water is essential for irrigation, so knowledge of water quality is critical. Additionally, water use in agriculture has been increasing in the last decades. Lack of water quality can cause drip clog, a lack of application uniformity, cross-contamination, and direct and indirect impacts on plants and soil. Currently, there is a need for more automated methods for evaluating and monitoring water quality for irrigation purposes, considering different aspects, from impacts on soil to impacts on irrigation systems. This work proposes a data-driven method to address this gap and implemented it in a case study in the PCJ river basin in Brazil. The methodology contains nine components and considers the main steps of the data lifecycle and the traditional machine learning workflow, allowing for automated knowledge extraction and providing important information for improving decision making. The case study illustrates the use of the methodology, highlighting its main advantages and challenges. Clustering different scenarios in three hydrological years (high, average, and lower streamflows) and considering different inputs (soil-related metrics, irrigation system-related metrics, and all metrics) helped generate new insights into the area that would not be easily obtained using traditional methods.

“…The process of pollution formation in RCS occurs with the crystallization of calcium carbonate (CaCO 3 ) and magnesium hydroxide (Mg(OH) 2 ). It is important to establish the chemical composition of pollution at industrial facilities, as it can explain the process of its formation and, accordingly, take measures to minimize it [26]. The importance of studying DP in RCS is emphasized by investigating the processes of formation of the heterogeneous phase of CaCO 3 [27][28][29].…”

The object of this study is the processes of formation and changes of dispersed particles in fresh, make-up, cooling, and return water in open recirculating cooling systems (RCS) with an assessment of the influence of suspended substances in discharge waters on the aquatic ecosystem. The study was carried out on the example of the Rivne Nuclear Power Plant (RNPP) and the Styr River. Dispersed particles (DPs) pose technological obstacles in the RCS of power plants, and their content in discharge waters determines the ecological quality of water bodies. This paper describes the results of studying the formation and changes of DP in raw, make-up, cooling, and return waters of RNPP RCS with an assessment of the impact of suspended substances in discharge waters on the aquatic ecosystem of the Styr River. It was found that the formed dispersed particles after water treatment by liming contain DP consisting of calcium carbonate and have a size of 10–30 μm. As a result of agglomeration of DP in RCS, they aggregate to 120–150 μm, and due to low sedimentation resistance (sedimentation time 0.97 h), they settle in RCS. As a result of the deposition of DP in RCS, their significant decrease in return water (min–max=7.31–16.12 mg/dm3) is observed, despite the increase in their content in make-up water after water treatment (min–max=10.22–49.46 mg/dm3). According to the ecological classification, according to the content of suspended substances, the water of the Styr River in the zone of influence of RNPP discharges belongs to the II class, category 2, which characterizes the quality of the water as "very good" in terms of its state, and "clean" in terms of its degree of purity. It was concluded that the content of suspended solids does not exceed the established maximum permissible concentration (25 mg/dm3), the increase in the concentration of suspended solids does not exceed the established ecological standard of 0.25 mg/dm3 and does not have a negative impact on surface water. The results of the research could be used for other power plants equipped with an open RCS
