Comparative study on the performance of typical coagulation-sedimentation and contact flocculation technology in treating high turbidity mine water
The main purpose of this study was to develop a contact flocculation treatment process for removing turbidity from three types of high turbidity mine water (HTMW), exploring the effects of various flocculants, dosages, filter materials, and filtration rates on turbidity reduction. Four different contact filtration media, named active filter, fiber ball filter, PET foam filter and comet-like filter were used. The results indicate that pretreatment with PAC and PAM can reduce the turbidity of HTMW to< 40TU, and the optimal flocculant dosages for PAC and PAM are 1.92 mg/L and 0.0021 mg/L, respectively. Besides, active filter media proved most effective in stability and turbidity reduction, with a recommended thickness of 43 cm and filtration rate of 40 m/h during the actual tests using HTMW. Under optimal conditions, the actual mine wastewater (MW1, MW2, MW3) was treated, and the effluent quality met the Class III standard for surface water quality in China, achieving a turbidity of < 5 NTU suitable for further treatment.
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
