Polyaluminum chloride (PAC)
Polyaluminum chloride is an inorganic polymer coagulant that generates high molecular weight and high charge inorganic polymer water treatment agents due to the bridging effect of hydroxide ions and the polymerization effect of multivalent anions.
Product Introduction
Mechanism of action of Wanpu water purification polyaluminum chloride:
Polyaluminum chloride is an inorganic polymer coagulant that generates high molecular weight and high charge inorganic polymer water treatment agents due to the bridging effect of hydroxide ions and the polymerization effect of multivalent anions. The molecular formula is as follows: AL2 (OH) nCL6-n] m (n is 3-5, m ≤ 10), where the coagulation effect is as follows:
Product Features
Performance of polyaluminum chloride produced by Wanpu Water Purification:
a、 Polyaluminum chloride, as a water treatment agent, has strong adaptability to various water qualities, and its coagulation and sedimentation effects are particularly significant for high turbidity water.
b、 The purified water quality is superior to inorganic coagulants such as aluminum sulfate, and the cost of water purification is 15-30% lower compared to it. The formation of flocs is fast and the settling speed is fast.
c、 High alumina content and low dosage can reduce the cost of producing water.
d、 The pH value of the source water can condense within the range of 5.0-9.0.
e、 Low corrosiveness, good operating conditions, and better solubility than aluminum sulfate.
f、 Treating water with less salt content is beneficial for ion exchange treatment and pure water preparation.
g、 The adaptability to source water temperature is better than inorganic coagulants such as aluminum sulfate, and the treatment effect on low-temperature water is also good, with a low precipitation temperature of -18 ℃.

Wanpu Water Purification High Speed: How to use your polyaluminum chloride:
a、 The dosage varies depending on the water being treated. Generally, the dosage for water purification is about 5-100 grams/ton for liquid products and 2-30 grams/ton for solids. If a small-scale trial is conducted, the effect will be better.
b、 Preparation: It can be directly added to the treated water, or diluted with water and added to the water. The amount of water added can be determined according to the dosage and the amount of treated water. After adding water, it should be stirred evenly.

Precautions for polyaluminum chloride:
a、 The aqueous solution prepared each time should not be left for too long to avoid reducing its effectiveness.
b、 The effective storage period of the product is six months for liquids and one year for solids. Solid products can still be used after being damp.
c、 Different manufacturers or brands of water treatment agents cannot be mixed and stored with other chemicals. They should be waterproof and moisture-proof.
