The SWE was found to have turbidity levels which require pretreatment, and microfiltration was chosen in this study for its ability to remove particles to 1 micron, its low-cost and the ease of operation and maintenance. Three commercially available NF membranes (NF90, NF245, and NF270) were evaluated using a bench-scale system operated in recycle mode, in which a fixed batch volume of SWE obtained from Tuba City, Arizona, was continuously recirculated through each membrane module. The NF90 membrane demonstrated the highest rejection of organic and inorganic compounds and consistently maintained a 96% reduction in total dissolved solids throughout 7 days of operation. In contrast, the NF245 and NF270 membranes showed decreasing performance over time due to fouling. All membranes successfully removed more than 95% of contaminants of emerging concern. Characterization of the membranes indicated changes in hydrophobicity and surface charge for NF245 and NF270 after SWE filtering, while the properties of the NF90 membrane surface remained relatively unchanged. The treated effluents from NF245 and NF270 met Arizona's Class A+ reclaimed water standards for non-potable reuse.

With the range of physical, chemical and biological interactions within DWDS the specific processes enabling particles to remain on pipe surfaces are not investigated or quantified here with the focus on delivering evidence based practical support.

Reynolds number is proposed to best describe the limit of sedimentation as a measure of the turbulence forces that are balanced by the self-weight forces. Shear stress, that quantifies surface forces, is proposed to best describe mobilisation. For practical guidelines and uptake these can be converted to velocities. Sedimentation was found to dominate up to a Reynolds number of 15 100 (0.25 m s<small><sup>−1</sup></small>, 0.21 N m<small><sup>−2</sup></small>); above this cohesive layers were dominant. This indicates discolouration risks from sedimentation, likely in the tertiary zones of a DWDS, may be mitigated if flows regularly attain these values.

The data on dimensions of water services were collected through household surveys. The Kruskal–Wallis test was adopted to determine if the differences found in quantitative dimensions of water services available to households across fast-urbanising villages and towns under urban administration were statistically significant, while a chi-square test was employed for qualitative dimensions. Our results showed no better services in towns under urban administration for all dimensions studied. If some were better in towns under urban administration, others were better in urbanising villages under rural administration.

The development of scalable and high-performance electrode materials is critical to accelerate the transition of CDI toward industrial and commercial adoption. Prussian blue (PB) and Prussian blue analogues (PBAs), with their open-framework crystalline structures, rapid and reversible ion-storage capabilities, and high theoretical capacitance, have recently gained attention as next-generation CDI electrode materials. Despite promising laboratory-scale results, key challenges including long-term electrode stability, large-scale synthesis, environmental compatibility, and reliable performance under real-water conditions remain unresolved.

Strategies such as multi-metallic analogues, hierarchical porous architectures, and hybrid composites with conductive materials are examined to enhance the desalination capacity, rate capability, and operational durability. Furthermore, critical barriers to commercialization including scalable and cost-effective synthesis, integration into modular pilot-scale systems, and performance in complex water matrices are discussed.
