Qingdao Shuodi Environmental Protection Technology Co., Ltd. is a professional supplier of polyaluminum chloride. Polyaluminum chloride (PAC) is an inorganic substance, an inorganic polymer coagulant, referred to as polyaluminum. It has a high-charged polymer chain body, has a high degree of neutralization and bridging effect on colloids and particles in water, and can strongly remove micro-toxic substances and heavy metal ions, with stable properties. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, the produced polyaluminium chloride is an inorganic polymer water treatment agent with a relatively large molecular weight and a high charge.
The colors of polyaluminum chloride are generally white, yellow, and brown, and the application and production technology of polyaluminum chloride of different colors are also quite different. It is also divided into industrial grade and drinking water grade. The aluminum trioxide content is 24%, 26%, 28%, 30% plate frame and spray type, polyaluminum chloride has better water solubility, and the dissolution process is accompanied by physical chemistry such as electrochemistry, coagulation, adsorption and precipitation. Changes, the formation of flocs is fast and thick, the activity is high, the sedimentation is fast, and the purification effect on high turbidity water is obvious.
It is used in industrial water supply and drainage, industrial wastewater, industrial circulating water and urban sewage purification, etc.
1. The packaging is double-layer packaging with inner film and outer woven bag, 25kg bag
2. The solid storage period is one year.
3. It should be kept in a dry, ventilated and cool place, and must not be exposed to moisture. It is strictly forbidden to mix with
Flammable, corrosive/toxic items are stored together.

After dissolving the solid product with water at a ratio of 1:3, add 10-30 times of water to dilute it to the required concentration before use. The optimal pH value of dosing is 3.5-5.0, choosing the best pH value to add can give full play to the maximum benefit of coagulation. The amount of dosage can be determined according to the different turbidity of raw water. Generally, when the turbidity of raw water is 100-500mg/L, the dosage per thousand tons is 5-10kg. When the turbidity of raw water is high, the dosage should be increased appropriately, and when the turbidity is low, the dosage can be reduced appropriately.
1. In low turbidity water, dilute the solid polyaluminum chloride product with tap water at a ratio of 1:3 (weight ratio), and stir until completely dissolved.
2. In domestic and production sewage, add about 30g of polyaluminum chloride products per ton of sewage. Then add the diluted polyacrylamide product. (If the effect is not obvious, please reduce or increase the dosage of the product as appropriate.)
3. In the sewage treatment of paper mills, the proportion of low-turbidity water is used. If the effect is not obvious, it can be added at discretion.
4. When the turbidity of raw water is 100-500mg/L, the dosage is 5-10mg, that is, the dosage per thousand tons of water is 5-10kg. put into use.
