[Product name] chloride, also known as multi-aluminum chloride English name for Polyaluminium Chloride, abbreviated as PAC. 【Properties】 According to the production process is different, generally divided into white, yellow and brown solid particles / flakes or brown liquid. Use products in drinking water, sewage, industrial water, industrial waste water, industrial water recycling, urban water supply and urban waste water purification, is currently the most widely used coagulant. Wherein the liquid product is suitable within 100 km of the user. [Advantages] 1, floc forming fast, fast settlement, good activity, good filtration, purified water is better than aluminum sulfate and other traditional products. 2, consume water alkalinity below various inorganic flocculants, which can vote or not vote less alkaline additives, such as the case deliquescence, its effect is the same. 3, to adapt to a wide PH value, the source water temperature adaptability than aluminum sulfate and other inorganic flocculants, widely used. 4, the treated water, less salt, ion exchange treatment and pure water control. 5, less corrosive, good operating conditions. 6, the active ingredient, ease of storage, transportation, cost, and the inorganic coagulant such as aluminum sulfate, 15-30% lower compared. 【Specifications】 PAC national standard GB15892-2009 Index Name GB15892-2009 liquid solid alumina (AL2O3) mass fraction /% ≥ 10.0 29.0 Basicity /% 40.0-90.0 Density (20 ℃) ??/ (g / cm3) ≥ 1.12 ---- insoluble mass fraction ≤ 0.2 0.6 PH value (10g / L aqueous solution) 3.5-5.0 Arsenic (AS) mass fraction /% ≤ 0.0002 Lead (Pb) mass fraction /% ≤ 0.001 Cadmium (Cd) mass fraction /% ≤ 0.0002 Mercury (Hg) mass fraction /% ≤ 0.00001 Hexavalent chromium (Cr +5) mass fraction /% ≤ 0.0005 Note: The liquid product listed in the table As, Pb, Cd, Hg, Cr +5 insoluble matter indicators according AL2O3 10% calculation, AL2O3 content ≥ 10%, they should be translated into actual amount of product AL2O3 10% of the impurities than the column index calculation. [Use] ⒈ approach different situations according to the raw water prior to use small test can do first obtain the optimal dose. For ease of calculation, a small weight ratio configuration test solution (W / W), generally with 2-5% as well. As with 3% solution: poly aluminum chloride solids 3g, poured into a wash 200ml graduated cylinder, add water about 50ml, to be dissolved with water diluted to 100ml mark, shake well. ⒉ production by poly aluminum chloride solids: water = 1:9 to 1:15 weight ratio (1:2 to 1:5 using liquid products) can be mixed and dissolved. Alumina content of less than 1% solution of easy hydrolysis will reduce the use of effects, the concentration is too high uniform dosing difficult. ⒊ dosing small test obtained by best dosage dosing and observe adjustments in the operation. See, for example less sedimentation tanks alum, I voiced large, the dosage is too small; see, for example alumina large settling ponds and on the turn, I turbidity is high, excessive dosing should be adjusted appropriately. [Note] ⒈ external plastic sacks, plastic film package, net weight 25kg, can be modified according to user requirements, while liquid PAC sales. ⒉ the goods prohibited mixed with toxic substances, transport and storage, the product should be stored in dry, ventilated, cool place, and do not get wet. ⒊ Handle with care when loading and unloading, the solid product storage period of one year.
