The Application of Epichlorohydrin-Dimethylamine Polymer Flocculant for Tannery Wastewater Treatment

Abstract:

A cationic organic flocculant epichlorohydrin-dimethylamine(EPI-DMA) was employed for the treatment of simulated leather-making process wastewater. The study aims at investigating the flocculation performance of EPI-DMA for the leather dyeing wastewater which contains fat-liquoring agent wastewater and retanning agent wastewater. The results show that decoloration efficiency of EPI-DMA for dyeing wastewater can reach around 90% with proper dosage. For containing retanning agent wastewater, EPI-DMA also has good flocculation performance, but for containing fat-liquoring agent wastewater, flocculation performance of EPI-DMA was poor.
