Special Issue Information

Dear Colleagues,

Sustainable water management is a critical human responsibility. Water surrounds us in our daily life; it is pure, transparent, life-sustaining and thirst-quenching. Nature is dependent on water to carry nutrients and oxygen to cells. It is an important medium in numerous technological processes, such as in carrying substances and generating power and electricity. The removal of components, the chemical activation of their surface and their preparation for decomposition, as well as the mineralization of raw materials during treatment, are critical economic and environmental engineering points for the processing of industrial and anthropogenic effluents. Today, the cleaning of environmental and industrial wastewater is carried out at different levels. The two most important processes in this regard are the mechanical separation of undigested contaminants and the breakdown of dissolved contaminants by microorganisms. The most common methods of dealing with this type of wastewater are physical, chemical and biological purification, in some combination. Water remediation faces a considerable challenge in the need to devise elaborate plans and strategies for managing drought, floods and treating polluted water of different origins. The magnitude, frequency and timing of water management could help to accommodate better practices in different fields. 

This Special Issue aims to provide information and research approaches aiding in water storage, water management, water remediation and water purification to better prepare for adverse environmental impacts.

Original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Water remediation;
  • Water management;
  • Water treatments;
  • Water storage and reuse;
  • Water purification;
  • Environmental effect of water;
  • Microbial fuel cells;
  • Water policy and strategy.

I look forward to receiving your contributions.

Water, energy, and food security are essential for maintenance and human survival. This research applied an approach for the water–energy–food system to a watershed in the Atlantic Rainforest in Southern Brazil. It is based on a WEAP system that was developed and evaluated future water demand scenarios for the 2020–2050 timespan. The Sustainability Index (SI) was used to assess the scenarios to propose an alternative to compare the current development trend. The results indicated that by 2050, the necessary flow for different water uses would be 78.75% greater than in 2020 while maintaining the present scenario (C_REF). Substituting part of the hydroelectric energy by photovoltaic solar energy (C_EAL), implementing watershed action masterplans as a water resource instrument (C_GES), and integrating these scenarios (C_INT) will reduce the current demand ranging from 8.96% to 24.59%. The average flow would decrease by 28.44% and 29.07%, respectively, by evaluating water availability in climatic change scenarios (C_MCL) for the RCP 4.5 and 8.5 scenarios. Compared with the reference scenario C_REF, C_INT presented an improved SI (0.1231), while C_MCL 8.5 presented the worse (−0.0047). Therefore, resources must be generated holistically so that one segment does not negatively impact the others. The findings highlight the pressing need for Santa Catarina State to implement effective management strategies targeting specific sectors, particularly the industrial and human consumption supply sectors. It is imperative to propose adaptation plans and implement actions that foster the reduction in water demands while also providing subsidies and guidance to the industrial sector on responsible water usage to prevent any negative impact on their productivity in the future. Comprehensive plans and policies should be formulated to ensure integration and coherence among various sectors involved in water resource management. Full article

The efficiency that drinking water suppliers have, is widely analyzed in the literature due to the importance of its proper diagnosis in the regulation of the sector. These regulations seek, via the reduction of inefficiencies, to counteract water access crises. This research calculates the level of input-oriented technical efficiency of Ecuador’s potable water service providers in the period 2014–2017. It analyzes its determinants, focusing on the effect of the geographic region (Highlands, Coast, and Amazon), as well as the type of management, specifically municipal departments and autonomous public enterprises. For this purpose, the semi-parametric method of data envelopment analysis (DEA) with double bootstrap is used. The results suggest that drinking water suppliers could save the inputs used while maintaining their level of production. In addition, it was found that the level of technical efficiency differs by geographic region but not by the type of management used. The natural Highlands region is more efficient compared to the Coast and Amazon region, suggesting climatic and natural resource distribution heterogeneities that induce this difference. The result by type of management shows that the advantages indicated by some literature regarding the technical, financial, and administrative autonomy of public companies may not improve efficiency compared to municipal departments.

In this research, amphiphilic derivatives of kappa carrageenan (KC) were synthesized by hydrophobic modification with an alkyl halide (1-Octyl chloride). Three hydrophobic polymers with different degrees of substitution (DS) were obtained by the Williamson etherification reaction in an alkaline medium. The effect of the molar ratio (R = reagent/polymer) on the DS was investigated at different ratios (1, 2, and 3). The KC derivatives (KCRs) were characterized by different techniques such as FT-IR, 1H-NMR, X-ray Diffraction, Scanning electron microscopy, and a rheological assessment. The FT-IR and 1HNMR analyses confirmed the binding of the hydrophobic groups onto the KC molecule. The degrees of substitution calculated by 1H-NMR demonstrated that the derivative KCR3 (0.68) presented a higher degree of substitution compared to KCR1(0.45) and KCR2 (0.53). The XRD and SEM analyses revealed that the alkaline etherification conditions did not alter the morphological and crystallographic properties, as well as the rheological behavior of the obtained derivatives. The amphiphilic character of the KCRs was investigated using a conductivity method which revealed that the molecular aggregation occurred above the critical aggregation concentration (CAC). Decreasing CAC values of 0.15% (KCR1), 0.11% (KCR2) and 0.08% (KCR3)with the degree of substitution (DS) were found. Furthermore, KCR’s derivatives greatly improved the stability of oil/water emulsions as the droplet size decreased with increasing DS. The derivative (KCR3) with higher DS, showed a greater amphiphilic character, and improved emulsifying power. Full article
