“…Although it was not affected by the treatments, the increase in soil ESP has been frequently reported by studies using treated effluents in irrigation, probably due to the concentration of sodium in water [57]. Urbano et al [17] observed that, after five cycles of lettuce cultivation under irrigation with wastewater, the physical properties of an Oxisol did not change.…”

The objective of this study was to evaluate the adsorption capacity of orange pomace biochar, applying its benefits in irrigated agriculture. For this, a low-cost system for tertiary treatment using biochar was developed. The objective was also to compare the physicochemical and microbiological attributes of irrigation water with the limits established by the legislation. The impacts of wastewater from the filtration system on the soil and on the agronomic and biological characteristics of the lettuce crop were assessed. Biochar was produced in a muffle furnace and characterized by thermogravimetry and scanning electron microscopy (SEM). The experimental design was randomized blocks, in a 5 (irrigation depths) × 5 (combinations of water sources and fertilization) factorial arrangement, with three replicates. It was found that the use of biochar as a filter material improved the microbiological quality of wastewater. The water sources used in irrigation did not cause changes in soil salinity. Fertigation using wastewater that passed through the filtration system positively affected the agronomic characteristics of lettuce, with no need for top-dressing fertilization. Lettuce leaves produced in the experiment were acceptable for human consumption, according to the standards of Resolution-RDC No. 12, of 2 January 2001, of the National Health Surveillance Agency (ANVISA).

“…A study conducted in South Africa revealed that in regions with low rainfall, irrigation with winery wastewater would lead to the spread of cations, increasing soil salinity (Mulidzi, Clarke, & Myburgh, 2020). Studies on the long-term effects of the use of untreated winery wastewater in the irrigation process showed a negative impact on soil structural stability (Liang, Rengasamy, Smernik, & Mosley, 2021;Mosse et al, 2012Mosse et al, , 2013. When the treated wastewater was applied, no significant differences in nitrogen and carbon cycling were detected in the short-term analysis (Mosse et al, 2012(Mosse et al, , 2013.…”

“…Physiochemical treatments of winery effluents use costly and high-energy-consuming screens and filters to remove salts and large particles. Similarly, biological treatments contribute to enhanced sludge formation and subsequent CO 2 emission during reduction in heavy organic load from winery wastewater. , The anaerobic digestion process, used widely to convert organics into a renewable energy (biogas), is unviable for medium- and small-scale wineries because of the high capital and maintenance costs. Over the years, the use of microalgae-based remediation of various types of wastewater for biofuel production has been shown to increase the sustainability and efficiency of the process besides reducing the cost of treatment. − …”

Wastewater utilization by microalgal strains is due to changes in the inherent phenotypic traits that enable metabolic flexibility, facilitating their adaptation to survive in harsh environments. However, the potential role of changed phenotypic traits such as physiological and metabolic activities required for enhanced biomass production remains largely underexplored. In this study, involving acid-tolerant microalgal strains, Desmodesmus sp. MAS1 and Heterochlorella sp. MAS3, we observed a timedependent growth increase (>300% after 1 week) under mixotrophic conditions. While transitioning to the second week, there was a change in growth pattern, with >600% increase in chlorophyll content and minor pH alterations, indicating the phenotypic response to the synergistic effect of nutritional mode during wastewater treatment. Both the strains showed a similar removal (70−80%) of both organic and inorganic carbon present in the wastewater, while the removal of nitrogen and phosphate (80−90%) was significant during mixotrophy. Metabolic analysis revealed the prominence of key pathways such as CO 2 fixation, nitrogen assimilation, and amino acid metabolism under mixotrophic conditions of an open system. Especially, strain MAS1 exhibited elevated expression of organic acids, suggesting their crucial role in nutrient uptake from winery effluents during mixotrophy. Thus, our study demonstrates that a synergy of wastewater environment and nutritional mode enhances phenotypic trait expression in microalgae to improve metabolic flexibility and sustainable biomass production.
