Aluminum sulfate, ferric sulfate, sodium silicate as the main raw material, prepared by polymerization of silicate iron (PSAF) flocculant. The effects of different Al / Fe / Si molar ratio, basicity B *) value, the impact of p H value, dosage and other factors on the flocculation and flocculation PSAF investigated and compared with traditional flocculant. The results show that: the p H value of 6-8, dosage of 1.5 × 10 - 5mol·L- 1 (with Si O2 meter), Huainan polymerization aluminum iron, PSAF in Al / Fe / Si molar ratio of 1 1: 1, B * is 0.8 when the best flocculation, flocculation to cloud outperforms aluminum sulfate, ferric sulfate and Polysilicate first published abroad poly aluminum flocculant (referred PSAA) successfully developed reported [1], the country in recent years carried out a thorough study of the polysilicate, PAC upgrade aluminum iron, and made a lot of progress [2-5]. Large amounts of data confirmed that the price of iron silicate polymerization, poly aluminum, iron coagulant than traditional flocculation aluminum, iron coagulant better. PAC domestic market shoddy phenomenon is very common adverse manufacturers, merchants vicious competition, phosphorus silicate iron desulfurization by now most of the units are using the lack of professional talent, superb technology and excellent laboratory equipment The instrument used to detect characteristics of PAC-related products indicators were shoddy false sales, get 28% -29% to 30% of goods posing as authentic, reduce the quality of PAC to get his invisible profits. I will teach you how to identify the pros and cons of PAC, please contact us. We will especially for your water quality, with our expertise, given the ratio of rationalization scheme, thorough and effective solution to your sewage problem.
