In this paper, granular alum sludge adsorbent (GASA) was manufactured using powdery alum sludge (PAS) as the raw material and methods such as gluing and pore-forming. The effects of different binders, pore-forming agents, roasting temperatures, and roasting times on the formation of GASA and its dephosphorization performance were investigated. Results showed that the optimum binder was AlCl3 at a mass ratio of 8%, and the best pore-forming agent was starch at a 4% dosage ratio. Meanwhile, the optimum roasting temperature and time were 500 \u00b0C and 2 hours, respectively. The specific surface area of GASA was 23.124 m2\/g. Scanning electron microscopy suggested that GASA's surface became rough, particles became tight, and average pore size increased, with additional pore channels. P adsorption by GASA reached 0.90 mg\/g. The effluent phosphorus concentration of actual tail water decreased to 0.49 mg\/L and the removal rate reached 73.5% when the GASA dosage was 20 g\/L. The findings of this study are important for the further development of a low-cost adsorbent material for P removal in the future.<\/jats:p>","DOI":"10.2166\/wst.2019.241","type":"journal-article","created":{"date-parts":[[2019,7,18]],"date-time":"2019-07-18T13:52:40Z","timestamp":1563457960000},"page":"2378-2386","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":24,"title":["Study on the preparation of granular alum sludge adsorbent for phosphorus removal"],"prefix":"10.2166","volume":"79","author":[{"given":"H.
