Abstract
The efficiency improvement of wastewater recycling has been prioritized by ‘Goal 6’ of the United Nations Sustainable Development initiative. A methodology is developed to synchronously profile multiple water-quality indices of a wastewater electrodialysis (ED) process. The non-linear multifactorial screener is exclusively synthesized by assembling proper R-based statistical freeware routines. In sync with current trends, the new methodology promotes convenient, open and rapid implementation. The new proposal unites the ‘small-and-fast’ data-sampling features of the fractional multifactorial designs to the downsizing, by microclustering, of the multiple water quality indices—using optimized silhouette-based classification. The non-linear multifactorial profiling process is catalyzed by the ‘ordinalization’ of the regular nominal nature of the resulting optimum clusters. A bump chart screening virtually eliminates weak performances. A follow-up application of the ordinal regression succeeds in assigning statistical significance to the resultant factorial potency. The rank-learning aptitude of the new profiler is tested and confirmed on recently published wastewater ED-datasets. The small ED-datasets attest to the usefulness to convert limited data in real world applications, wherever there is a necessity to improve the quality status of water for agricultural irrigation in arid areas. The predictions have been compared with other techniques and found to be agreeable.
Highlights
Water is indispensable to life, but its chemical behavior perpetually remains a great enigma [1,2]
It may be inferred that working with a three-clustered dataset will be advisable, since the average silhouette width (ASW) value is maximized at a value of 0.61
Improving wastewater recycling efficiency is necessary for sustainable agricultural irrigation
Summary
Water is indispensable to life, but its chemical behavior perpetually remains a great enigma [1,2]. This is because the mysterious inner workings of water have not been adequately deciphered yet—in its basic role to mediate nature’s processes [3]. Water is a universal solvent that covers two-thirds of the earth’s surface [4]. The water concentration in the human body is about 70%—the main constituent. Replenishing this amount requires a daily intake of a few liters of clean water. To converge on targets 6.3 and 6.A—by 2030—there is a clear direction with great emphasis on “water efficiency, wastewater treatment, recycling and reuse technologies” [13]
