DOI: 10.21443/1560-9278-2018-21-1-80-87 85 According to the research conducted, the EPS obtained from active sludge with the EDTA and CH 3 COOH methods have good flocculation and are harmless for humans and the environment, and thus may be a potential substitute for traditional synthetic flocculants in the wastewater treatment of fish processing plants.
