“…In surface or ground waters, one finds iron and manganese in different chemical forms (dissolved, precipitated, free or complexed) and in variable concentrations (Myint and Barry, 1999;Omoregie et al, 2002;Muwanga and Barifaidjo, 2006). They may be present in concentrations of about 2 to 5 mg/L of iron and 0.5 to 2 mg/L of manganese (Ellis et al, 2000;Roccaro et al, 2007) or in concentrations that are markedly higher and capable of attaining 20 mg/L of iron and 5 mg/L of manganese (Berbenni et al, 2000).…”

“…Predominantly physical processes like clarification and adsorption on precipitates or activated carbon are evoked (Llofd et al, 1983;Aziza and Smith, 1992;Okoniewsk et al, 2007). Simple membrane techniques often preceded by oxidation are also cited among the processes of water deferrization and demanganization (Ellis et al, 2000;Teng et al, 2001;Choo et al, 2005).…”

Okpara dam water contained significant amounts of iron and manganese that could be problematic for consumers. In this study, we perfected a deferrization and demanganization technique by coagulationflocculation preceded by chlorination. The maximum iron and manganese concentrations varied from 30 to 50 mg/L and 1.5 to 4.5 mg/L respectively before treatment. Purification yields depended on the conditions of operation. Under the least favourable conditions (coagulation at free pH), the removal yields varied from 10 to 73% for iron and from 2 to 24% for manganese. Under the best conditions (pre-chlorination and coagulation at pH 6.5), we obtained between 50 and 95% elimination for iron and 20 and 45% for manganese. The treatment was therefore little adapted for the removal of manganese.

“…This sediment is the oxidized or ferric form of iron that will not dissolve in water. There are several methods for removal of iron from drinking water like ion exchange and water softening (Vaaramaa and Lehto, 2003), activated carbon and other filtration materials (Munter et al, 2005), bioremediation (Berbenni et al, 2000), oxidation by aeration, chlorination, ozonation followed by filtration (Ellis et al, 2000), by ash (Das et al, 2007), by aerated granular filter (Cho, 2005) and by adsorption (Tahir and Rauf, 2004).…”

“…Several techniques have been applied to remove these metals from groundwater including ion-exchange and water softening, adsorption by activated carbon, aeration and filtration, biosorption, ionic liquid extraction, and so forth [6][7][8][9][10]. Recently, the application of membrane technology including nanofiltration (NF) in water treatment for producing drinking water resources has been increased rapidly.…”

Iron and manganese present naturally in groundwater. Both metallic ions at excessive amounts normally contribute to rusty taste and reddish color to the water. Membrane technology may improve the conventional groundwater treatment method which commonly requires a large area and a lot of manpower. The present experimental work focused on membrane filtration of iron and manganese in order to study the influence of pH adjustment to the prepared artificial groundwater based on the permeate quality and membrane performances. In this study, two commercially available polyamide nanofiltration and ultrafiltration membranes (PA-NF, PA-UF) were tested to examine their capabilities in treating groundwater for drinking water resources. In order to achieve WHO drinking water standard, permeate quality of the artificial groundwater is considered satisfy if concentration of iron and manganese has reached 0.3 and 0.1 mg/L, respectively. Experimental results showed that pH at a range of 3-11 have significantly improved membrane performance in terms of their rejection. Rejection of iron at a feed concentration of 100 mg/L increased as pH of the feed solution increased for all tested membranes. However, the manganese rejection with a feed concentration at 50 mg/L showed various pattern of performance for each membrane. The pH of feed solution played an important role in changing the membrane surface properties and also, the characteristic of solute. This concludes that solutemembrane interaction mechanism has improved the performance of the tested membranes.

Kedua-dua ion logam ini pada jumlah yang berlebihan menyumbang kepada rasa berkarat dan warna yang kemerahan pada air. Kajian ini memberi tumpuan kepada penurasan logam besi dan mangan oleh membran dengan tujuan untuk mengkaji kesan pelarasan pH terhadap air bawah tanah buatan berdasarkan kepada kualiti telapan dan prestasi membran. Dalam ujikaji ini, dua membran poliamida penurasan-nano dan penurasan-ultra (PA-NF, PA-UF) yang boleh didapati secara komersial telah diuji untuk mengkaji keupayaan dalam merawat air bawah tanah sebagai sumber air minuman. Untuk mencapai piawaian WHO bagi air minuman, kualiti telapan air bawah tanah buatan dianggap memuaskan jika kepekatan besi dan mangan masing-masing mencapai 0.3 dan 0.1 mg/L. Keputusan ujikaji menunjukkan bahawa pH di antara julat 3-11 dengan ketaranya telah menambahbaik prestasi membran dari segi penyingkiran. Penyingkiran besi pada kepekatan suapan 100 mg/L telah meningkat apabila pH suapan meningkat untuk semua membran yang diuji. Walau bagaimanapun, penyingkaran mangan dengan kepekatan suapan pada 50 mg/L menunjukkan kepelbagaian corak prestasi bagi setiap membran. pH larutan suapan memainkan peranan penting dalam mengubah sifat-sifat permukaan membran
