Effect of Temperature on Polyaluminium Chloride

Polyaluminium chloride is a very good water purifier and is widely used in some water treatment industries. Why is the use of polyaluminium chloride at low temperatures influencing the effect of polyaluminium chloride

Polyaluminium chloride is more affected at low temperature and low turbidity, but is less affected at high temperature and high turbidity, and its flocculation effect will be affected when the temperature reaches -5 C. Where the temperature is too high, it will be affected slightly.

The flocculation effect is affected when the temperature is -5 C. It is important to know that many molecular structures change from very active to suspended, usually due to temperature changes. From the internal structure analysis, PAC is also in this field. The molecular structure of PAC is stable at 5 ~20 ~C.

When the temperature drops below zero, the molecules begin to stop moving, which will affect the application of PAC. The direct manifestation is that flocculation is not contradictory. It is difficult to form silk flower, and the adsorption will not achieve the purpose of adsorption, further affecting its deposition. In winter weather like this, many local temperatures drop below zero, making it difficult for PAC to perform. The main reason is that the molecular structure changes from a very active state to a stationary state, most of the time due to temperature changes, and polyaluminium chloride is also included in the internal structure analysis.

The general treatment method is to heat the temperature of sewage water and then put flocculant on it. Of course, this method is of high cost. Or wait until the sun shines directly at noon until the temperature rises.
