Henan BK water purification flocculant plant production and supply to the country each full-content PAC, over the years the new and old customers of the wastewater treatment industry widely used, the effect is good, price concessions, I plant the production and supply to the provinces and cities new and old customers PAC PAC 3 tons from custom, high quality excellent price! 2013 to all new and old customers to inquire Order! Zhangjiakou PAC Price Hotline: 15639099789 0371-85022211 Henan Billions Branch water purification flocculant plant will receive customer advisory: I do not know how to use efficient water purifying agent poly aluminum chloride for water purification, that today come to you talk about its principle! Detailed summary for PAC water purification principle four points, specific electric double layer is compressed, and adsorption power, bridging adsorption mechanism of precipitate netting four aspects. 1, the compression of the electric double layer: Micelle electric double layer structure to determine the concentration of counter-ions at the micelle surface, with the larger the distance outwardly micelle surface Counter-ion concentration is lower, the final ion solution concentrations are equal. When the dosing electrolyte to the solution, and the solution ion concentration diffusion layer is reduced in thickness. Actually coagulant dosing in aqueous solution the colloidal destabilization phenomena related to the three aspects of the interaction of colloidal particles with coagulant, particles with an aqueous solution, coagulant and aqueous solution, is an integrated phenomenon. 2, adsorption power: adsorption power and refers to the particle surface parts of opposite sign ions of different signs the colloid or chain from molecules with opposite charge strong adsorption, and it is due to this adsorption The part of the charge to reduce the electrostatic repulsion, thus close to each other easily with other particles adsorbed. In this case, the static gravitational often the main aspects of these effects is, but in many cases, the effect of other than electrostatic attraction. 3, bridging adsorption: adsorption bridging mechanism mainly refers to the adsorption and bridging of polymer material and colloidal particles. Can also be understood as two of the middle of the same number of colloidal particles have a different number of colloidal particles connected together. High-molecular flocculant having a linear structure, they have a chemical group that can work with certain parts of the surface of the micelle, the group with the surface of the micelles have a special reaction, when the when high polymer micelle contact with each other adsorption , while the rest of the molecule of the polymer is stretched in a solution, there is a vacancy in micelles and their other surface adsorption, so that the polymer plays a role of bridging connections. If the colloidal particles is small, the adhesion of the polymer extending portion vain second micelle, this extending portion sooner or later will be the original colloidal adsorption on in other parts of this polymer can not play the role of the bridging, micelles Also in the steady state. Polymer flocculant dosing is too large, will make the micelle surface saturation re-stabilize the phenomenon. The bridging flocculation particles, such as by violent agitation for a long time, the cross-linked polymer may be disengaged from the other colloidal surface, weight and volume back to the original where the colloidal particle surface, resulting in steady state again. The price of the basic aluminum chloride: http://www.bkscl.com 4 precipitate netting mechanism for metal salts (such as aluminum sulfate or ferric chloride) or metal oxides and hydroxides (such as lime), coagulant when dosing quantities sufficient to rapid precipitation of metal hydroxides (such as Al (OH) 3, Fe (OH) 3, Mg (OH) 2 or a metal carbonate (CaCO3), water micelles these precipitate formed when the netting in neutral and acidic pH range when the precipitate is positively charged (Al (OH) 3 and Fe (OH) 3), the sedimentation rate may exist due to the solution of the anion accelerated, for example, silver sulfate ion addition micelles in water can be used as the core of these metal oxide oxide precipitate formed, so flocculating agent optimum dosage and inversely proportional to the concentration of the substance is removed, i.e. the more micelle metal flocculating dosage is less.
