Activated carbon aided alum coagulation for removal of textile dye from dye water

Activated carbon aided alum coagulation for removal of textile dye from dye water / Er Eng Kien
Penyingkiran tiga jenis celupan tekstil (CIBACRON Yellow C5G, Remazol Blue RGB and Remazol Red RGB) dari air dengan eksperimen dalam skala makmal telah dinilai melalui proses penyerapan diikuti pengentalan. Pemeriksaan tentang keberkesanan penyerapan oleh serbuk karbon diaktifkan (powdered activated carbon, Malbon R4) terhadap ketiga-tiga jenis celupan juga telah dijalankan. Eksperiment yang telah dijalankan menunjukkan peningkatan penyerapan dengan peningkatan kepekatan celupan dan karbon. Urutan operasi yang tepat bagi sistem rawatan bergabung telah dikenalpasti. Keputusan menunjukkan bahawa penyingkiran celupan maksimum dalam peratusan oleh penyerapan karbon mencapai 52.15-83.53 %. Penyingkiran celupan maksimum untuk ketiga-tiga celupan dengan kepekatan 20 mg/l dan 50 mg/l dengan proses penyerapan diikuti pengentalan adalah masing-masing 96.16-99.78 % dan 96.71-99.60 %. Proses bergabungan penyerapan-pengentalan berkemampuan untuk menyingkirkan hampir kesemua celupan dalam air. Penyelidikan yang lebih harus dilakukan bagi jenis karbon dan pengental yang berlainan dalam penyingkiran celupan dalam air sisa. _______________________________________________________________________________________________________ The processes of adsorption followed by coagulation was evaluated for the removal of three textile dyes (CIBACRON Yellow C5G, Remazol Blue RGB and Remazol Red RGB) from water in a laboratory-scale experiment. The adsorption efficiency of manufactured powdered activated carbon (Malbon R4) for three dye solutions was also investigated. Batch experiments showed that the adsorption of dyes increased with an increase in dye concentration and carbon dose. The right sequence of operation was identified for the combined treatment system. The results indicated that maximum percentage of dye removal by adsorption on Malbon R4 for the dyes achieved was 52.15- 83.53 %. The maximum dye removal efficiencies for 20 mg/l and 50 mg/l of dye concentration (for three dyes) with adsorption followed by coagulation were 96.16-99.78% and 96.71-99.60 %, respectively. The combined adsorption-coagulation process has the capability of near complete dye removal. More research should be done with different types of activated carbons and coagulants for removal of dye from dye wastewater.
