Polyaluminium ferric chloride is a very good water purification agent product at present, and it still has good effect even in low temperature environment. Gongyi Filter Industry Co.,Ltd is a production of poly aluminum ferric chloride enterprises, today to analyze the poly aluminum ferric chloride low temperature why still has a good effect.

Polyaluminium ferric chloride is an inorganic polymer flocculant for water purification. Compared with many water purification agents, polyaluminium ferric chloride has the advantages of good flocculation effect and wide range of wastewater treatment. Because polyaluminium ferric chloride is a new type of water purification agent which is polymerized by iron salt and aluminum salt, it also has the characteristics of fast sedimentation rate, good water purification effect in low temperature environment, and wide pH range of polyaluminium ferric chloride.

Polyaluminum ferric chloride can still have a good water purification effect at low temperature, mainly because the iron ion in polyaluminum ferric chloride polymerizes with aluminum salt in the production process to form a multivalent form of iron ion. At this time, the iron ion is much less affected by temperature in sewage treatment. At the same time, the aluminum ions in the polyaluminum ferric chloride itself have good water purification effect at low temperature, so the polyaluminum ferric chloride formed by the combination of the two still has good water purification effect at low temperature.

Although polyaluminium ferric chloride has a good water purification effect at low temperature, it has been found through long-term practice that polyaluminium ferric chloride has a certain requirement on the pH value of sewage if it wants to play a better water purification effect at low temperature. However, polyaluminium ferric chloride is more adaptable to the pH value of sewage at room temperature, so it is necessary to carry out small-scale test to determine the use method of polyaluminium ferric chloride at low temperature.
