      performance and floc aggregation properties.

AB  - A cationic organic flocculant epichlorohydrin-dimethylamine (EPI-DMA) was 
      employed for the treatment of acid and direct dye. The study aims at 
      investigating the flocculation performance of EPI-DMA for the model dye, and 
      corresponding floc aggregation properties, which were determined by jar test and 
      photometric dispersion analysis, respectively. The interactions between cationic 
      flocculant and anionic dye were investigated through spectra analysis. The 
      results showed that EPI-DMA effectively decolorized the tested acid and direct 
      dye. The viscosity and cationicity of EPI-DMA had different influence on the 
      removal of different dye. Chemical interaction was observed between quaternary 
      ammonium of EPI-DMA and sulfonic group of dye. The flocculation dynamic process 
      showed that flocs with better aggregation and sedimentation properties were 
      produced by EPI-DMA with higher viscosity and cationicity for acid dye. 
      Contrarily, flocs with the best aggregation and sedimentation properties were 
      produced by EPI-DMA with the lowest viscosity and cationicity for direct dye.
