“…It is well known that NH 3 is a crucial industrial raw material utilized in the production of fertilizers, chemicals, textiles, and paper products. 27,28 Meanwhile, it is also a toxic gas that can cause severe respiratory irritation and lead to various health issues such as vomiting, headache, pneumonia, and even death. 29,30 As for the substrate, layered transition metal dichalcogenides (LTMDs) have become a new generation of semiconductor for gas sensor materials due to their excellent properties such as ultra-high surface-volume ratio, extensive chemical composition.…”

The adverse effects of air pollution on human health, climate change, and ecosystems have made air pollution a major problem in the last four years. Ammonia is a pollutant that has an impact on human health. This study aims to develop a monitoring system for NH3 concentrations using radio communication. The radio module used in data communication is SX1278. The sensor used in this system is MICS-6814, which is integrated with Arduino Nano. The sensor used has been tested and can be used in emission detection. Monitoring results data is displayed on the LCD and serial monitor. Data communication performance for the monitoring process was tested at various distances. This system can reach a measurement distance of 80 meters, with the best distance used for monitoring being less than 50 meters. This system was tested to be able to monitor a different level building. The result shows that the system's performance is the RSSI at a distance of 0 meters is -28 dBm. At the same time, the farthest distance of 80 meters is -101 dBm. The data transmission has a delay time of 1,300 ms and an accuracy of 91%. The ambient NH3 concentration in the area of Malang is found in the range of 0.001 ppm.

“…The search for efficient solutions for recycling and reuse of resources, as well as the development of more sustainable and efficient technologies, can lead to significant improvements in wastewater treatment processes [11][12][13][14][15]. In this regard, the literature presents various opportunities that can contribute to significant improvements in wastewater treatment processes [12,[16][17][18][19][20]. Life cycle analysis, sewage sludge recovery, reuse of treated water, or optimization of treatment processes are just a few examples of good practices that are currently successfully applied in wastewater treatment plants [21,22].…”

In the context of ever-increasing water demand and pressures on natural resources, efficient water management is becoming a major priority for contemporary society. Since nitrogen and phosphorus, as essential nutrients, play a crucial role in the dynamics of aquatic ecosystems, but excessive concentrations can cause eutrophication of receptors, they need to be eliminated as completely as possible while respecting the principles of a sustainable economy, efficiency, and quality. In this study, the efficiency of optimizing the technological process of wastewater treatment by dosing FeCl3 40% solution to reduce nitrogen and phosphorus concentrations in treated water was investigated. The results obtained revealed that the use of this type of flocculant resulted in an increase in the efficiency of the removal process of total N by an average of 35.57 mg/L and total P by an average of 3.89 mg/L. Also, the results, which are interpreted by mathematical modeling, show that the optimal use of FeCl3 40% solution leads to a significant reduction in pollutants, well below the maximum permitted values (according to Romanian regulations, the maximum value for total phosphorus is 2 mg/L and total nitrogen is 15 mg/L for localities with a population between 10,000 and 100,000 inhabitants). This technical approach not only improves the quality of treated water but also contributes to minimizing the impact on aquatic ecosystems and promotes the principles of circular economy in water resource management. By optimizing the dosage of FeCl3 40% solution in the treatment process, the efficiency of the coagulation and flocculation processes is maximized, thus providing a viable and sustainable solution for reducing the environmental impact of nitrogen and phosphorus and promoting responsible and sustainable water resource management.
