Polyaluminium chloride is easily soluble in water and has strong bridging adsorption properties. During the hydrolysis process, physical and chemical changes such as electrochemistry, coagulation, adsorption and precipitation occur. This product is mainly used for the purification of drinking water and the treatment of industrial wastewater, such as wastewater containing radioactive substances, lead (Pb++), chromium (Cr+++), highly toxic heavy metals and fluoride (F). In addition, it is also widely used in high-precision casting, papermaking, leather making, etc. Polyaluminium chloride is an inorganic polymer coagulant, referred to as polyaluminium, or PAC in English. It is an inorganic polymer water treatment agent with a large molecular weight and a high charge produced by the bridging effect of hydroxide ions and the polymerization of multivalent anions. Polyaluminium chloride is a new type of purification material, an inorganic polymer coagulant, also referred to as polyaluminium. It is an inorganic polymer water treatment agent with a large molecular weight and a high charge produced by the bridging effect of hydroxide ions and the polymerization of multivalent anions. Polyaluminium chloride is in the form of golden, khaki, brown or red granules/flakes. The water quality after purification is better than that of aluminium sulfate coagulant, and the water purification cost is 15-30% lower than that of aluminium sulfate. The floccules are formed and settled quickly, and the processing capacity is greater than that of traditional products such as aluminium sulfate. It can consume water with alkalinity lower than that of various inorganic coagulants, so no or less alkali agent is required. The applicable raw water PH range is 5.0-9.0. It has low corrosiveness, good operating conditions, better solubility than aluminium sulfate, and better applicability to source temperature than inorganic coagulants such as aluminium sulfate.
1. It has unique performance in treating papermaking and printing and dyeing wastewater.
2. It has fast flocculation and precipitation, and can increase production capacity by 1.5-3 times under corresponding conditions.
3. Under the same dosage, the hardness of water consumed during coagulation is less than that of various inorganic coagulants, and the pH value of treated water is also reduced less.
4. When treating high-concentration water, alkaline additives and organic coagulants can be added without or with less addition.
5. Its decolorization ability is better than other inorganic water purifiers.
Polyaluminium chloride is a new type of purification material, an inorganic polymer coagulant, also known as polyaluminium for short. It is an inorganic polymer water treatment agent with a large molecular weight and a high charge produced by the bridging effect of hydroxide ions and the polymerization of multivalent anions. Polyaluminium chloride is in the form of golden yellow, khaki, brown, or red granules/flakes. The quality of the purified water is
better than that of aluminium sulfate coagulant, and the water purification cost is 15-30% lower than that of aluminium sulfate coagulant. It has fast floc formation and sedimentation speed, and has a greater processing capacity than
traditional products such as aluminium sulfate. It can consume water with alkalinity lower than that of various inorganic coagulants, so no or less alkali agent can be added. The applicable raw water PH range is 5.0-9.0. It has low
corrosiveness, good operating conditions, better solubility than aluminium sulfate, and better applicability to source temperature than inorganic coagulants such as aluminium sulfate.
