| 總結: | Groundwater can be an alternative source to meet the demand for clean water
supply. Unfortunately, lots of contaminant present in groundwater have made it
unsafe for domestic use and drinking. Therefore, groundwater should be treated to an
acceptable level before consumption. The overall aim of this study is to improve
groundwater quality using Integrated Groundwater Treatment System (IGTs). The
system was designed and installed in the hydro-meteorology station at UTHM.
Initially, hydrochemical characterisation of the groundwater were determined using
piper diagram and statistical analysis. The optimum conditions for each treatment
system were identified prior to the installation of IGTs. The system consists of
several treatments namely pre-aeration, post-aeration, sedimentation, filtration with
customised filter tank and ceramic filter, and dilution with harvested rainwater. From
the results obtained, major cation and anion found were Na and Cl, respectively. The
type of water that predominates the study area is Na–Cl which indicates that the
groundwater is influenced by seawater intrusion. For post-aeration and sedimentation
processes, the most suitable time taken ranged between 18 hours and 48 hours. For
filtration, the most suitable customised filter tank was Filter type D with brick layer
as the dominant component. Meanwhile, ceramic filter was selected to be used in the
candle filter. Using IGTs, the system was able to reduce concentrations of TDS, Na,
Cl, Fe, and Mn by 70.3%, 23.42%, 81.81%, 90.48%, and 61.62%, respectively. Due
to very high concentrations of parameters in the study area, not all parameters met
the Drinking Water Quality Standard and Recommended Raw Water Quality
Standard by Ministry of Health Malaysia. Overall, the study results could serve as
important baseline information for authorities in Malaysia to plan and manage
groundwater in the future. |
