Application of Polyaluminum chloride
Polyaluminum chloride is a kind of new and efficient water-soluble inorganic polymer flocculant for water purification, which is non-toxic and harmless. Its principle of action is to destabilize, aggregate, flocculate, coagulate, and precipitate fine suspended particles and colloidal ions in water through adsorption neutralization, adsorption bridging, compression of double electric layers, and sediment net capture, achieving the purification effect. Polyaluminum chloride can remove bacteria, odor, fluoride, aluminum, chromium, oil, turbidity, heavy metal salts, radioactive pollutants, and has a wide range of applications in purifying various water sources.
Application of Polyaluminum chloride
1. Water treatment
Polyaluminum chloride can be applied to printing factories, printing and dyeing factories, leather factories, breweries, meat processing factories, pharmaceutical factories, paper mills, coal washing, metallurgy, mining areas, as well as the treatment of wastewater containing fluorine, oil, and heavy metals, as well as in the fields of daily life wastewater, chemical wastewater, and industrial wastewater treatment.
2. Mining industry
Polyaluminum chloride flocculants have excellent performance in the mining industry, used for ore washing and separation of minerals. On the one hand, they separate water from gangue, facilitating water reuse, and on the other hand, polyacrylamide dehydrates the generated sludge.
3. Oil extraction
Polyaluminum chloride is the main material used for wastewater treatment in petroleum exploitation. It is used as an oil displacement agent, water plugging regulator, drilling fluid regulator, and fracturing fluid additive in petroleum exploitation.
4. Paper industry
Polyaluminum chloride is mainly used in the papermaking industry as a neutral sizing and settling agent for rosin, retention aid, filter aid, as well as to control familiar obstacles and serve as a capture agent for anionic impurities, in addition to being partially used for sewage and clean water treatment (in papermaking).
5. Textile printing and dyeing industry
The wastewater generated by the textile printing and dyeing industry has the characteristics of large water volume, deep chromaticity, and high content of organic pollutants, making it one of the most difficult to treat industrial wastewater. Through the action of polyaluminum chloride, the alum flower is solid and large, the sedimentation rate is fast, and the treatment effect is obvious in the wastewater treatment process; In addition, polyaluminum chloride is also used for wrinkle resistance in leather and cloth.
Soil crust has the properties of high surface density, small pores, and low saturated hydraulic conductivity, which can hinder soil water infiltration, increase surface runoff, and hinder seed germination. The role of polyaluminum chloride is to increase soil moisture content, inhibit soil crust formation, and increase water infiltration.
7. Daily chemical industry
Food grade polyaluminum chloride is a high-end product in water purification flocculants, which has more significant effects on flocculation and sedimentation of wastewater in daily chemical production. In addition, food grade polyaluminum chloride is also used as raw materials or additives in pharmaceutical, cosmetics, and beauty industries.
8. Aquaculture industry
Polyaluminum chloride is used in the aquaculture industry to effectively remove organic matter from water. When there is too much organic matter in the water, a large amount of organic matter in the water is first precipitated by physical and chemical methods (such as using polyaluminum chloride), and then an oxidizing agent is added, or EM bacteria and photosynthetic bacteria are used, and new algae species are implanted to accelerate the energy flow and material cycle of the pond. When there is too much organic matter in the water, the method of settling organic matter in the water is particularly crucial, The use of polyaluminum chloride should also be one of the effective options.
polyaluminum chloride can be applied to cement solidification, mold casting, and refining of pharmaceuticals, glycerol, and sugars.
