| Private Drinking Water Flocculant Preparation and properties of PAS
3 and compare the effect of other flocculant PAS in order to further examine the processing performance of the Yangtze River, the election of aluminum polymer, poly alumina comparative experiment, the results shown in Table 1 deal with different flocculants Table l Comparison of the Yangtze River Water Table 1 can be seen,timberland shoes, comprehensive removal, flocculation and sedimentation properties of the water quality and other aspects, PAS aggregate coagulation is superior to aluminum and alumina together, and the rapid formation of alum, floc density, settling quickly, more water clear, no residual aluminum. Out of the water, Huangshi Institute of Technology, 2008 Zhu, A is the body with the most trace elements,ugg boots italia, and human health are closely related; A is pro-biological metals, healthy environment. Therefore,timberland boots, the poly silicon titanium sulfate is a green-friendly flocculants, flocculant can be used as drinking water special. 4 Conclusion (1) PAS preparation and selection of acid A solution of compound polysilicate, nA / nsi = 0.3 is the best ratio. (2) PAS Yangtze River water to deal with the best agent, when the dosage as 10mg / L,ugg italia, pH = 6 ~ 8 ʱ, PAS in the treatment effect,ugg italia, uV254 removal efficiency greater than 61.7%, turbidity removal of more than 99%. (3) PAS is a green-friendly flocculants, can be used as drinking water of the Yangtze Special flocculant. |
