First, to determine the water quality of the steel plant are mostly positive charge or negative charge, if the performance of the positive charge on the use of an anionic flocculant, if performance is negatively charged cationic flocculant is chosen, when the anionic flocculant and cationic flocculant performance effects are not too Well, then consider a non-ionic flocculant. Steel plant sewage treatment flocculant determine specific model. Steel plant used in determining ionic flocculant, you need to choose the most appropriate model. At this point, you need to consider the flocculant molecular and ionic degrees, steel mills using medium can be. Flocculation test selected by the best selection, sewage supernatant most clear, cost-effective model. Steel plant sewage treatment flocculant determine the amount of use. Steel plant in the use of flocculants, flocculant needs to be dubbed a fraction to four thousandths of an aqueous solution, but not the higher the concentration, the better, of course, not the larger dosage of flocculation, the better . Steel plant flocculant to determine the best dosage beaker through repeated use can be determined, depending on the water quality, adding different amounts of flocculants.
