Abstract
Desalination can be implemented to ensure sufficient water supply for agricultural and economic sectors, as well as daily population demand. This detailed study explores various methods for handling brine discharge in Malaysia by analyzing environmental regulations and practices from other countries. A survey of 20 expert engineers from the Department of Environment Malaysia (DOE) and community leaders has been conducted in the study. Later, a Fuzzy Delphi Method (FDM) was used to evaluate the key parameters of temperature limit (P1), pH limit (P2), salinity impact zone (P3), and salinity limit (P4) from the questionnaire. The assessment indicated fuzzy scores of 0.770, 0.790, 0.792, and 0.803 for P1–P4, respectively. Moreover, factors such as the construction of a desalination plant need to be included in prescribed activities under the EIA Guidelines (S1, S2) and regulated under the Environmental Quality Act 1974 (S3). The fuzzy scores for S1, S2, and S3 were 0.803, 0.743, and 0.725, respectively. The approach with the highest fuzzy score was identified as the most acceptable. This study provides valuable insight for Malaysia to develop sustainable brine waste management strategies and enhance existing environmental regulations.
