Abstract

Several desalination systems with distinct operational principles have been developed to enhance the generation of freshwater and optimize system efficiency. Adsorption desalination (AD) systems are highly desirable because to their ability to simultaneously achieve desalination and cooling using minimal energy input. These systems offer significant cost savings in terms of maintenance compared to conventional desalination systems. In order to gain a comprehensive understanding of the fundamental constituents of this desalination technology, the present study initially expounds upon the theory of adsorption and the process of circulation. Aims: The aim of this study is to conduct a thorough analysis of adsorbents for adsorption desalination and adsorption desalination technologies, and investigation into their potential integration with established conventional cycles, including multiple-effect distillation (MED), solar regenerable, and integrated evaporator-condenser cycles. Methodology and results: The findings of this study involve the evaluation and summarization of pertinent research on the fundamental aspects of the adsorption desalination system. These aspects include the thermodynamic process and cycle, performance assessment, adsorbents, and adsorption desalination technologies. The location, heat energy supply, collector, evaporator, condenser, adsorption desalination, adsorbent materials, and findings are investigated. Conclusion, significance and impact study: The discourse pertaining to prospective avenues of research, which will prove beneficial for analogous investigations within this domain, reaches a culmination.

Abstract

Urban activities and runoff deteriorated the river water. Aim: This study aims to determine the primary contamination and mapping river's water quality variation in Greater Jakarta. Methodology and Results: Multivariate analysis was employed by Factor Analysis and Cluster Analysis (FA and CA) using the 12 parameters of the water quality dataset from 76 sampling stations in 19 rivers in the Greater Jakarta Region, Indonesia, between 2014 and 2015. The FA result showed that almost 66.6% of the total variance in water quality data was associated with four significant variators of which 36.12% identified the main parameters BOD, COD, TP, ammonia, nitrate, and detergent. The cluster analysis grouped the sampling locations into 3 (three) clusters to indicate the spatial classifications of river water. Cluster 1 indicates pollutants from the residential area, Cluster 2 from residential and commercial areas, while Cluster 3 is majorly pollutants from industrial areas. Conclusion, significance, and impact study: The results showed the conductivity and TDS concentrations in cluster 3 are higher than the others since most of the sampling points are located near an industrial area or downstream close to the estuary. The mapping gave a better understanding of the river water quality characteristic spatially and could assist local governments in prioritizing river pollution management.
