| Summary: | Population growth, urbanization, industry, and irrigation agriculture have all caused the rise
in the need for treated water resources. In addition, there is a shortage of treated water for
potable water use where treated water is also used for non-drinking purposes. Most water
sources in Sarawak are severely affected due to aquaculture, household sewage, and
fertilizers from agricultural activities, all of which contribute to the increase in solid waste
and suspended chemicals. These factors have contributed to the reduction of river water
quality in Malaysia, especially in Sarawak. The presence of contaminants in water leads to
the critical need for an efficient water filtration process. The project studies the water quality
parameters of different water sources such as rivers, lakes, rainwaters, etc. The water quality
parameters can be categorized mainly into three main categories which are physical
(turbidity), chemical (pH, hardness, BOD, COD, TSS, iron concentration, copper
concentration, and manganese concentration), and biological (E. coli) properties. The
separate filter media filtration system was used to study the media performance. It was found
out that the silica sand 0.6mm media were effective for turbidity, TSS, hardness, and BOD
reduction. Apart from that, the activated carbon was efficient for E. coli treatment, whereas
the zeolite media was better in pH and COD removal. On the other hand, most filter media
managed to treat a water sample to comply with the raw water quality standard after the first
cycle except for COD and BOD treatment. Lastly, this study shows the operating conditions
and the quality of treated water for all media have a very high negative correlation, where
the overall water quality decreases as the filtration cycle increases. Therefore, the
improvement of the existing filter media must be implemented by studying the appropriate
water treatment cycle process to improve the quality of treated water in meeting the
requirement set by the Department of Environment Malaysia. |
