This research was to investigate the feasibility of using water hyacinth fiber filter sheet with natural rubber latex (NRL) as binder to treat 3 reactive dyes (2% Red, SBN, 2% Blue G and 2% Yellow RN). The water hyacinth fiber (WHF) was obtained by sodium hydroxide solution modification. To determine the contact time of WHF, the optimal contact time at 3 days was achieved. In addition, the adsorption capacity of 3 reactive dyes were 1.14, 1.20 and 1.51 mg/g respectively. At the concentration of 3 reactive dyes solution 20, 10 and 10 mg/L respectively and the 1 g of WHF, the color value of the treated solution were not over 300 ADMI (standard value of wastewater industry). The optimal ratio by weight of WHF to NRL was 1: 2. Furthermore, the dyes removal efficiency of WHF filter sheet was determined in the 3 mixed dyes solution. The experimental results revealed that the WHF filter sheet size 5x16 cm could remove 3 reactive dyes until 640 mL of the mixed dyes solution 10 mg/L was thoroughly passed. Therefore, this WHF filter sheet has enough potential to remove these 3 reactive dyes.
