Solid polyaluminum chloride and liquid polyaluminum dosage depends on what factors? Solid polyaluminum chloride and liquid polyaluminum dosage depends on what factors? Filter water purification by long-term production and found that polyaluminum dosage depends on the treatment of raw water turbidity, and what kind of water quality and its water treatment with the reaction tank structure, different structures of the pool, the reaction time , The flow rate is not the same, the final dosage of polyaluminum is not the same. First, the solid polyaluminum chloride dosage Polyaluminum chloride solid inorganic polymer coagulant, the color is: golden yellow, khaki, brown, red granular / flake powdery solid, the general treatment of raw water purification Of its dosage is about one hundred thousandth of water (1 liter of water add 0.01 grams), purified water better than aluminum sulfate flocculant, water purification costs compared with low 15-30%, floc Forming fast, settling speed, processing power than the traditional products such as aluminum sulfate, water consumption of alkalinity is lower than a variety of inorganic flocculant, which can not vote or less investment alkali agent to adapt to the source of water PH5.0-9.0 range Agglomeration, less corrosive, good operating conditions, better solubility than aluminum sulfate, the treatment of salt increased less, is conducive to ion exchange treatment and high-purity water, adaptability of the source water temperature better than inorganic flocculants such as aluminum sulfate. Second, the liquid polyaluminum chloride dosage Poly aluminum chloride liquid products can be adapted to the PH value range of 5.0-9.0, the best PH value of 6.5-7.6, the product can be added directly or diluted 10 times after dosing, solid Product dilution 5-10% liquid dosing, favorable uniform mixing, the effect is good, the diluted solution is best used within 4-8 hours. Polyaluminum chloride liquid can be applied to river, lake and groundwater treatment, industrial water and industrial recycling water treatment, can be applied to coal mining wastewater and porcelain industrial wastewater recycling, can be used in printing, dyeing, tannery, Brewing plants, meat processing plants, pharmaceutical plants, paper mills, coal washing, metallurgy, mining and the treatment of wastewater containing fluorine, oil and heavy metals can be applied to the crease-free of leather and cloth. Can be used as a good catalyst, can be applied to cement solidification and molding casting; pharmaceuticals, glycerol and sugar refining; paper bonding. To sum up: We can see the water quality determines the amount of polyaluminum chloride, depending on the water quality, the amount will be different, such as raw water turbidity 100-500mg / I, the dosage of 3-6mg / I. Solid polyaluminum chloride (solid) and water at room temperature by 1/3 weight ratio while stirring dosing until completely dissolved, and then diluted with water to the desired concentration of raw water concentration of 100 ~ 500mg / d dosage of 3 ~ 6mg / L. Specific dosage of polyaluminum chloride, water quality should be based on water test, select the best dosage and then put into use.
