Properties of polyaluminium chloride

1. Wide range of application and wide adaptability to water.2. It is easy to form large alum flowers quickly and has good precipitability. The flocculate formed by coagulation reaction is coarse, not easy to be broken, has good recondensability, fast settling speed, good filtration of settling water, strong compressibility of sediment, and easy to dehydrate. The water quality after purification is better than inorganic coagulant such as aluminum sulfate, and the cost of water purification is 15-30% lower than that.3. Due to the rapid coagulation reaction, strong neutralization and destabilization force, long molecular chain link and rapid bridging, the product can overcome the difficulties of low temperature and low turbidity water treatment.4. The suitable range of pH value is wide (5-9), and the pH value and alkalinity of treated water decrease little.5. When the water temperature is low, it can still maintain a stable precipitation effect.6. Its alkalinity is higher than other aluminum and iron salts, and it is easy to dissolve in water, convenient to use and stable in quality. The solubility is better than aluminum sulfate, and the corrosion to equipment is small.7. The flocs produced by this product are in network shape and have large specific surface area, so it has strong adsorption and removal effect on iron, fluorine, arsenic and bacteria in water.
