Polymerized Aluminum Ferric Chloride (PAFC) is a new type of composite amorphous, inorganic polymer water purification agent with aluminum as the main ingredient and iron as the supplementary ingredient.Iron is highly valent and forms polynuclear complexes upon hydrolysis.At low temperatures, it has the characteristics of forming in the water, such as the specific gravity and the tightness of the alum flower.This is mainly due to the iron salt hydrolysis rate and the hydrolysis process by the temperature is very small effect of the reason.Due to less iron content, it won't reduce the PH value of water and increase the chromaticity of effluent too much, and due to the decolorizing performance of aluminum salt, the chromaticity of effluent is greatly reduced. So it has the characteristics and features of PAC and iron salt. It overcomes the difficulty of water purification when PAC is in low temperature and low turbidity.Therefore, its water purification effect is obviously better than water purification products. This product is developed on the basis of in-depth research on the hydrolysis and coagulation mechanism of polymerized aluminum chloride and iron oxide, aluminum salt and iron salt coagulant, he set the advantages of aluminum salt and iron salt coagulation, and there is an obvious improvement in the aluminum ion and the form, and the degree of polymerization is also greatly improved.
Polymerized aluminum ferric chloride first diluted with water, diluted aqueous solution in the addition of sewage.
1. Dilution ratio 100:5 or 100:3,That is, 100 ml of water plus 5g or 3g of polymerized aluminum chloride dilution and stirring, stirring for 15-20 minutes into an aqueous solution.
2. Use ratio 100:0.5-2, that is, 100 ml of sewage plus 0.5-2 ml of water solution. Dilution ratio is fixed, the use of the ratio needs to be determined according to the sewage situation.
The liquid product is brown or reddish brown transparent, no precipitation.
The solid product is brownish, reddish brown powder or grain, very soluble in water.
Used for domestic drinking water, domestic sewage, industrial water and industrial sewage treatment.Coagulation effect in addition to the performance of the remaining turbidity and color reduction, but also has a floc formation fast, high adsorption performance, sludge filtration and other characteristics, especially in the treatment of high turbidity water and low-temperature low-turbidity water, the treatment effect is better than alum, polymerized aluminum chloride, polymerized ferric sulfate, ferric chloride, in which the purification of low-temperature and low-turbidity water is especially obvious, without adding alkaline additives or other coagulant aids, with other coagulants can not be compared with the effect of the coagulant.
