Introduction and application of high efficient polyaluminum chloride

High efficiency polyaluminum chloride is a kind of water purification material, inorganic polymer coagulant, also referred to as polyaluminum, and its English abbreviation is PAC. It can be used for water purification treatment: domestic water, industrial water, urban sewage treatment, industrial wastewater, sewage, sludge treatment and some residue recovery in sewage. In addition, for some industrial sewage with great difficulty in treatment, high-efficiency polyaluminum chloride PAC is used as the parent, mixed with other agents to prepare composite PAC, The treatment of sewage can achieve surprising results.

High efficiency polyaluminum chloride can be divided into solid and liquid in form. The solid can be divided into brown, beige, golden yellow and white according to the color. The liquid can be colorless, transparent, yellowish, light yellow to yellowish brown. The polyaluminum chloride of different colors also has great differences in application and production technology, and the formation of alum is fast; The particles are large and heavy, the precipitation performance is good, the dosage is generally lower than that of aluminum sulfate, and the stable coagulation effect can still be maintained when the water temperature is low. Therefore, it is more suitable in northern China.

High efficiency polyaluminum chloride PAC has large molecular structure, strong adsorption capacity, small dosage, low treatment cost, strong adaptability, and is less affected by the pH value and temperature of water body. After purification, the raw water reaches the national drinking water standard, and the content of cation and anion in the treated water is low, which is conducive to ion exchange treatment and the preparation of high-purity water. It has good solubility and high activity. The alum formed by coagulation in water body is large and settles quickly, It is 2-3 times larger than other inorganic flocculants in purification capacity, less corrosive and easy to operate. It can improve the labor intensity and labor conditions of the dosing process. It can achieve good coagulation effect on the raw water with serious pollution or low turbidity, high turbidity and high chroma. Its alkalinity is higher than other aluminum salts and iron salts. Therefore, the chemical solution has little corrosive effect on the equipment, and the pH value and alkalinity of the treated water decrease slightly.

High efficiency polyaluminum chloride shall be stored in a dry, non direct sunlight and well ventilated warehouse. It shall not be mixed with strong alkaline chemicals. Liquid products shall be transported to the warehouse by tank trucks or packaging barrels, and can be directly added as required. When solid products are used, water shall be added to dilute them into a solution with 5% - 15% alumina content according to actual needs (depending on the process design in use and working site conditions), Through the dosing system (such as metering pump) or directly into the water to be treated. The specific dilution method is as follows: inject clean water into the dissolving tank (pool) according to the calculated amount, start the mixing, and pour the polyaluminum chloride powder into the water according to the calculated amount (attention shall be paid to avoid direct contact with the product during the operation, and goggles, rubber gloves, work clothes, etc.) and keep stirring until the product is completely dissolved, At this time, the obtained high-efficiency polyaluminum chloride solution can be added to the water to be treated or stored for standby.
