“…Findings from CW2 validate; bricks (due to their expansive surface area and pores) functioned as filters and effectively absorbed total suspended particles from wastewater. A study by Javani et al (2016) produced similar results, showing that geotextile sheets and structural brick debris significantly impacted the removal of TSS contaminants in treated municipal wastewater. Saeed et al (2018) conducted an experiment using recycled bricks to treat industrial wastewater, with findings consistent with our experiment, indicating that bricks are valuable for removing TSS.…”

Traditionally constructed wetlands face significant limitations in treating tailwater from wastewater treatment plants, especially those associated with sugar mills. However, the advent of novel modified surface flow constructed wetlands offer a promising solution. This study aimed to assess the microbial community composition and compare the efficiencies of contaminant removal across different treatment wetlands: CW1 (Brick rubble, lignite, and Lemna minor L.), CW2 (Brick rubble and lignite), and CW3 (Lemna minor L.). The study also examined the impact of substrate and vegetation on the wetland systems. For a hydraulic retention time of 7 days, CW1 successfully removed more pollutants than CW2 and CW3. CW1 demonstrated removal rates of 72.19% for biochemical oxygen demand (BOD), 74.82% for chemical oxygen demand (COD), 79.62% for NH4+-N, 77.84% for NO3−-N, 87.73% for ortho phosphorous (OP), 78% for total dissolved solids (TDS), 74.1% for total nitrogen (TN), 81.07% for total phosphorous (TP), and 72.90% for total suspended solids (TSS). Furthermore, high-throughput sequencing analysis of the 16S rRNA gene revealed that CW1 exhibited elevated Chao1, Shannon, and Simpson indices, with values of 1324.46, 8.8172, and 0.9941, respectively. The most common bacterial species in the wetland system were Proteobacteria, Spirochaetota, Bacteroidota, Desulfobacterota, and Chloroflexi. The denitrifying bacterial class Rhodobacteriaceae also had the highest content ratio within the wetland system. These results confirm that CW1 significantly improves the performance of water filtration. Therefore, this research provides valuable insights for wastewater treatment facilities aiming to incorporate surface flow-constructed wetland tailwater enhancement initiatives.

“…Therefore, application of statistical and probabilistic methods for analysis of water resources in Iran has gained significant interest over the past few years (Araghinejad et al 2018). The increasing population of Iran has and will continue polluting surface and groundwater and will put water resources under pressure (Javani et al 2016;Sedaghatdoost et al 2019). Changes in temperature and precipitation due to global warming (Fayaz et al 2020) can exacerbate this situation.…”

Improper use of chemicals in irrigation practices is one of the prime concerns for widespread surface and groundwater pollution in agricultural areas; thus, it is vital to improving chemical application through proper fertigation managements. This research focuses on the impact of shape, slope, and fertigation timing on furrow irrigation performance. The results demonstrated that the effects of furrow shape, bed slope, and timing of fertigation were statistically significant, and altering these parameters would change the absorbed nitrate and nitrate loss amounts.
