22 May 2018 /Accepted: 22 July 2018 ABSTRACT The El-Nino phenomenon in early
2014 contributed to the lack of water supply in most Southeast
Asian countries. Suggestions have since been made to ensure the
continuity of water supply, one of which involves membrane technology
to treat mine water so that it is compatible for citizens’ use.
Accordingly, the objective of this research was to study the efficiency
of membrane technology in treating mine water. Our elucidation
of all the parameters has showed that the best attainable classification
is at Class IV. Although it was still regarded as polluted, the
treated mine water can be used as water supply reservoir. For
the membranes tested such as ultrafiltration 10 kDa, 5 kDa and
reverse osmosis, the percentage of rejection for chemical oxygen
demand is 21-72%, 40-96% for total suspended solids and 21-72%
for ammonia nitrogen. The pH also gradually shifted to almost
neutral after the filtration. Keywords: Heavy metal; mine
water; membrane technology; water quality parameter; water reuse ABSTRAK Fenomenon cuaca El-Nino pada
awal 2014 menyumbang kepada kekurangan bekalan air di kebanyakan
negara di Asia Tenggara. Objektif kajian ini adalah untuk mengkaji
kecekapan teknologi membran untuk rawatan air lombong dengan membandingkan
parameter kualiti air sebelum dan selepas penurasan berdasarkan
Indeks Kualiti Air (WQI)
seterusnya memberi cadangan reka bentuk loji rawatan air yang
merawat air lombong dengan menggunakan teknologi membran. Semua
parameter yang dikaji menunjukkan bahawa klasifikasi maksimum
yang tercapai adalah Kelas IV. Berdasarkan WQI,
walaupun semua air lombong dianggap tercemar tetapi ia masih dapat
digunakan sebagai sumber air takungan. Nilai WQI yang berada dalam lingkungan
47-65 dikategorikan sebagai Kelas III dan IV. Untuk membran yang
diuji seperti penurasan ultra 10 kDa, 5 kDa dan osmosis songsang,
peratusan penolakan untuk permintaan oksigen kimia adalah 21-72%,
40-96% untuk jumlah pepejal terampai dan 21-72% untuk nitrogen
ammonia. pH juga beransur-ansur berubah hampir ke neutral selepas
proses penurasan dijalankan. Kata kunci: Air lombong; logam berat; parameter kualiti air; penggunaan
