Polyaluminum chloride (PAC) is a new water treatment material, an inorganic polymer coagulant with adsorption, coagulation, and sedimentation properties. Despite some disadvantages, PAC offers the advantages of low dosage , low sludge formation, high turbidity removal rate, and minimal impact on wastewater pH, making it an ideal coagulant for wastewater treatment.
How does polyaluminum chloride (PAC) work effectively? Shaanxi Lianhe Xingchuang International Co., Ltd. (PAC supplier ) will explain it in detail .
Polyaluminum chloride (PAC) is used as a water treatment agent . Depending on the turbidity of the source water, seasonal fluctuations, and pool type, the user can determine the appropriate dosage, thus achieving optimal use and economic benefits.
Liquid and solid products can be added directly to water to create a 3–5% aqueous solution (based on Al2O3 content). The total dosage is 10–20 ppm.
Polyaluminum chloride (PAC) is used for paper sizing at a dosage of 1–3 parts aluminum sulfate, which corresponds to 2–3% based on absolutely dry paper. For bleaching and brightening in the sugar industry, this product is first prepared as a 3–5% aqueous solution (with Al₂O₃) and then added to the decolorized sugarcane juice at a dosage of 5–10 ppm.
Polyaluminum chloride (PAC) is capable of effectively removing various toxic and harmful contaminants from water. Its dosage is significantly lower than that of conventional inorganic water softeners, which reduces production costs.
The purification process is significantly simpler than conventional methods. It features high coagulation and sedimentation efficiency at low temperatures, significantly increasing the efficiency of solid-liquid separation and sedimentation. Furthermore, it enables filtration and drying of the sediment, which shortens the sediment’s residence time in the settling tank and increases the efficiency of water treatment.
Shaanxi Lianhe Xingchuang International Co., Ltd. specializes in the production of water treatment chemicals, disinfectants, scale inhibitors, food additives, oil exploration chemicals and pharmaceutical intermediates such as polyacrylamide, polyaluminum chloride, polyferrous sulfate and gluconic acid food additives in feed, etc.
