Usually there are six colours of
polyaluminium chloride white, light yellow, golden yellow, brown, brown and coffee, the polyaluminium chloride sold on the market is more complicated, because each merchant’s process and raw materials are different, and the colours are also different. 1,
white polyaluminium chloride, is a newly developed new type of water purification materials, specially used in food, drinking water, urban water supply, water purification, paper industry, pharmaceuticals, sugar refining, cosmetic additives, daily chemical industry and so on. The application range is very wide, the purity is very high, and the price is also high。 2,
light yellow polyaluminium chloride, second only to white polyaluminium chloride media and series products, mainly used for drinking water treatment, its colour is similar to millet yellow, there are strict restrictions on the content of heavy metals, in particular, our drinking water grade polyaluminium chloride products are treated, the water is clarified and no precipitation, the content of AL2O3 is about 30 (± 0.5), the powder is fine, the particles are homogeneous, the flocculation effect is good, the purification effect is good and stable, and the dosage is Low dosage and low cost. It is a kind of water treatment flocculant, applicable to all major water plants with long-term cooperation. 3、Golden yellow polyaluminium chloride, is currently widely used in the market polyaluminium chloride, AL2O3 content of about 222228 (± 0.5), used in sewage treatment flocculant, flocculation effect is good, so both the industrial water supply industrial wastewater, industrial water recycling and municipal wastewater treatment is the choice. 4, brown, brown and coffee-coloured polyaluminium chloride, is a water treatment products, for individual customer’s special requirements for water treatment, in which the iron content is higher than other polyaluminium chloride product series, so the colour is darker than gold. Effective for low temperature, low turbidity, high algae sewage, mainly used for drinking water treatment, urban water supply and industrial water purification. Specific operation precautions are as follows: In operation, the water purification process of polyaluminium chloride is generally divided into three stages. These three stages are aggregation stage, flocculation stage and precipitation stage. In the coagulation stage, when the chemical solution is injected into the coagulation container and the raw water solidifies rapidly, fine phlegm is formed in a very short time, at this time, the water body becomes more turbid and strong turbulence is required for water flow. Then, the polyaluminium chloride enters the flocculation stage, the flocculation stage is the process in which the sericeous flowers grow and thicken, proper turbulence and sufficient residence time (10 to 15 minutes) are required, and a large number of scented flowers can be observed to sink slowly at a later stage. A clear surface layer is formed. When the flocculant is in the settling stage, the process of flocculation and sedimentation in a settling tank requires slow water flow. In order to lift the rate, an inclined tube or plate settler is usually used and the inclined tube (plate) wall blocks a large number of coarse filament flowers. Sediment is deposited at the bottom of the tank and the upper layer is clarified water. 1. The remaining small-diameter and small-density flowers fall slowly, and they continue to collide with each other, and the residual turbidity remains essentially unchanged. 2. Polyaluminium chloride should be stored in a dry, moisture-proof, heat-resistant place (<80°c, do not destroy the packaging, product can be stored for a long time). 3. poly aluminium chloride products should dissolved before use. dissolving equipment and dosing facilities made of corrosion-resistant materials. 4. effective storage period polyaluminium liquid is half year, solid two years, still used after humidity.
