Valuation of Industrial Water Quality on Coconut Composite as Filter Media

摘要

Deterioration of surface water quality is the effect of anthropogenic activities in research areas due to rapid industrialization. The study was conducted to determine the spatial variation of the water quality of the industrial water effluent following the Malaysian National Quality Standard (MNQS). This research highlights the use of coconut activated carbon (CAC) as a raw material with epoxy resin and a hardener to form coconut composite (CC). The pH, total dissolved solids (TDS) and electrical conductivity (EC) parameters of the MNQS were collected before and after filtration by filter media to meet the objectives. The Taguchi method design parameters were used to minimise variance before optimising design for the output parameters to meet mean target values. Then, the study continued with the confirmatory tests to ensure that the results of the experiment were valid and completed. As for pH test experiment, the optimum parameters were for CAC 13.4 and epoxy resin, hardener 2.7. As for TDS and EC test experiment, the optimum parameters were for CAC 14.1 and epoxy resin, hardener 2.7. All data are valid as an error of less than five per cent based on confirmation testing.
