A seed crystal medium was developed from the powder steel slag and other material in order to carry out a novel method for phosphorus removal and recovery through the crystallization process. Continuous-flow fixed-bed column experiment was conducted to investigate the phosphorus removal capacity with low P concentration (10mg/L), and the influences of HRT, Ca/P ratio and pH on the treatment efficiency were also considered. It was observed that the P concentration of filter effluent was always lower than 0.5mg/L whether under the experimental condition of pH=7 and HRT=60 min or the condition of pH=7, HRT=30min and the Ca/P ratio = 1.5. With the HRT 30min, increasing pH to 7.5 and decreasing Ca/P ratio to 1, the P concentration of filter effluent was still lower than 0.5mg/L. The XRD analysis of the sediment obtained from the filter bed proved that product formed in the phosphorus removal process was Hydroxyapatite (HAP), illustrated that the crystallization occurred in the process of P-removal. The results of this study suggest that the fixed bed - phosphorus crystallization process with seed crystal media is a promising technique for phosphorus removal and recovery.

The application of polymers as a tool in the crystallization process is gaining more and more interest among the scientific community. According to Web of Science statistics the number of papers dealing with “Polymer induced crystallization” increased from 2 in 1990 to 436 in 2020, and for “Polymer controlled crystallization”—from 4 in 1990 to 344 in 2020. This is clear evidence that both topics are vivid, attractive and intensively investigated nowadays. Efficient control of crystallization and crystal properties still represents a bottleneck in the manufacturing of crystalline materials ranging from pigments, antiscalants, nanoporous materials and pharmaceuticals to semiconductor particles. However, a rapid development in precise and reliable measuring methods and techniques would enable one to better describe phenomena involved, to formulate theoretical models, and probably most importantly, to develop practical indications for how to appropriately lead many important processes in the industry. It is clearly visible at the first glance through a number of representative papers in the area, that many of them are preoccupied with the testing and production of pharmaceuticals, while the rest are addressed to new crystalline materials, renewable energy, water and wastewater technology and other branches of industry where the crystallization process takes place. In this work, authors gathered and briefly discuss over 100 papers, published in leading scientific periodicals, devoted to the influence of polymers on crystallizing solutions.
