Understanding of PAC flocculant products, filter water purification materials Xiaobian (+ 86-15639065815) Please come together to understand this knowledge, affordable, is a new type of high efficiency flocculants and water purification agent, a wide range of applications, Alkali chloride [Al2 (OH) nCl6-n], whose monomer is liquid, has wide range of preparation raw materials, low cost and low cost. Its chemical composition is Al2O3 (25% ~ 34%), SiO2 (40% ~ 50%), Fe2O3 (0.5% ~ 3.0%) and a small amount of impurities and water. Polyaluminium chloride, abbreviation PAC [Molecular formula] [AL2 (OH) LnCL6-n] m [Technical standards], the quality of PAC flocculant products in line with national GB15892-2003 standards, and other coagulation In contrast, the precipitation performance is good, easy to quickly form a large alum, PAC product PH value range of a wide range (5-9), and after treatment of water PH value and alkalinity decreased, when the water temperature is low, Can still maintain a stable precipitation effect, alkalinity than other aluminum salts, iron salts, the role of small equipment erosion.
Polyaluminum chloride flocculant products mainly through the action of compressing double layer, adsorbing neutralization, adsorption bridging and sediment net arresting mechanism to destabilize finely-suspended particles and colloid ions in edema, gather, flocculate and coagulate , To achieve the purification effect, in use, the product (solid) and room temperature water at a weight ratio of 1/3 while stirring while dosing until completely dissolved, and then diluted with water to the desired concentration of raw water concentration of 100 ~ 500mg / hour when the dosage is 3 ~ 6mg / I. Specific dosing, water quality should be based on water test, select the appropriate dosage and put into use, the effect is significant.
In use, according to the different conditions of raw water, before use can be done on a small test to achieve the ideal dosage and observe the adjustment during operation, in order to facilitate the calculation, small test solution configuration by weight (W / W), general With 2 to 5% as well. If equipped with 3% solution: said polyaluminum chloride solid 3g, into a clean 200ml measuring cylinder, add about 50ml of water, to be dissolved and diluted with water to 100ml scale, shake well.
Normally, it can be mixed and dissolved by solid: water = 1: 9 to 1:15 by weight (liquid product is 1: 2 to 1: 5). The solution with the content of aluminum oxide less than 1% Reduce the use of effects, concentration is not easy to vote evenly.
Solid PAC PAC flocculant products are 25kg bags, the inner plastic film, the outer plastic woven bags, PAC flocculant products should be stored indoors in dry, ventilated, cool place, and do not Moisture, should be stored in dry, direct sunlight, well-ventilated warehouse, not mixed with strong alkaline chemicals in order to maintain its best efficacy.
Poly aluminum chloride raw materials are aluminum hydroxide, calcium powder, bauxite, hydrochloric acid and so on. Polyaluminum chloride production methods: a,
