“…Some findings of water quality tests indicate that particulate matter from the atmosphere was the predominant pollutant in the RWH collection system [32], making rainwater stored in barrels inadequate for human consumption [33]. Studies suggest that pollutants can build up on a roof over an extended dry period, causing pollutant concentrations to be higher.…”

Roof runoff is collected rainwater from a roof using a rainwater harvesting system (RWHS). The construction of an efficient RWHS requires a thorough analysis of the rainwater quality and the appropriate treatment process for its intended use. In line with this, a bibliometric and comprehensive review of studies related to roof rainwater harvesting was conducted. A corpus of 1123 articles was downloaded from the Scopus database and parsed through the CorText Manager to determine the relationships between keywords, journals, and topics related to rainwater harvesting. A comprehensive analysis was also conducted to determine the different designs of RWHS, the quality of harvested rainwater from roof catchments, the efficiency of the system for specific purposes, and its sustainability in terms of economic, environmental, and social aspects. Results show that the effectiveness of a RWHS heavily depends on its installation site, the physicochemical characteristics of the harvested rainwater, and the acceptability of the end users. An effective water treatment process is essential for achieving better water quality for harvested rainwater. Moreover, assessing the financial viability and return on investment of an RWHS is necessary.

“…Much has been said about physical and chemical methods; however, few works talk about how to clean water using radiofrequency. An example of such a work is seen in [13], where a radio frequency (RF) treatment system is introduced to purify the water from the source with a small chance of contamination. RF is generated by applying a frequency of 1.5 MHz through a 2 mm diameter glass reactor that is wrapped by a 2 mm copper wire.…”

In this work, issues of water separation and purification are addressed, where, in order to achieve the desired results, it is necessary to use several disciplines such as classical physics, biotechnology, automatic control, automation, and applications of industry 4.0. Further, the need for comprehensive and automated solutions for rainwater treatment in the agricultural sector is addressed. This research focuses on designing and implementing a system adapted to these needs using Siemens technologies. The methodology ranges from the design of the Piping and Instrumentation Diagram (P&ID) to the implementation of the interface, incorporating Siemens technologies for data acquisition, electrical connections, treatment programming, and PID controller design. The results show significant advances in the development of the system, highlighting the effectiveness of automation and the HMI-PLC human–machine interface in process monitoring and control. These findings support the viability of a comprehensive rainwater treatment system for the agricultural sector, with important implications for water efficiency, environmental preservation, and increased productivity in agricultural and livestock activities. The contribution of this work is the relationship between engineering and research focused on industrial processes. The scientific contribution is to obtain the dynamic models and apply two strategies to obtain the gains of the PID controller. The first method is performed through the proposal of a Hurwitz polynomial, and the second is performed through genetic algorithms (GA), where they are implemented in a controller that is commonly used in the industry. The technological part includes the integration of work (schemes, programming, and communications) so that the result is as close to what was expected.

Non-Thermal Plasma as an Alternative to Enhance the Early Growth Structures in Lentil Plants

The scarcity and contamination of water, aggravated by the effects of Climate Change, endanger the food supply, cause health problems to humans, and are a critical concern. New research has been carried out to improve the quality of water used in the agricultural sector. One of them is the technology of non-thermal plasma (NTP) generated by corona discharges using air as a working gas. In this study, the NTP is applied directly and causing the activation to three water sources: potable, wastewater from poultry farming, and rain, on the legume “lentil.” The results show that the NTP applied to the different water conditions modifies the legume structure, obtaining a better germination and growth rate. In particular, it found that the best condition to stimulate the plant structure growth is using wastewater from poultry activities, which NTP activates. Likewise, it identified the internalization of pathogenic microorganisms such as Escherichia coli and Salmonella typhimurium since the early development of the plant. The bacteria reduction after NTP application is detected due to the effect of the reactive species generated by the NTP. The NTP application for water activation can represent an alternative to solve the demand for food since the development of the structures of legumes, particularly of lentils, is promoted.
