Product Description
Polyaluminium chloride is an inorganic polymer coagulant, also known as
polyaluminium, abbreviated as PAC. It is an inorganic polymer water treatment
agent with a large molecular weight and a high charge produced by the bridging
effect of hydroxide ions and the polymerization of multivalent anions. In terms
of form, it can be divided into solid and liquid. Solids are divided into brown,
yellow and white according to different colors. Polyaluminium chloride of
different colors also has great differences in application and production
technology. Twenty-eight percent of polyaluminium chloride is soluble in water
and has strong bridging adsorption properties. During the hydrolysis process,
physical and chemical changes such as electrochemistry, coagulation, adsorption
and precipitation occur. This product is mainly used for the purification of
drinking water and the treatment of industrial wastewater, such as wastewater
containing radioactive substances, lead (Pb++), chromium (Cr+++), highly toxic
heavy metals and fluorine (F). In addition, it is also widely used in
high-precision casting, papermaking, leather making and other aspects.
Polyaluminium chloride is a new type of purification material, inorganic polymer
coagulant, also known as polyaluminium for short. It is an inorganic polymer
water treatment agent with a large molecular weight and a high charge produced
by the bridging effect of hydroxide ions and the polymerization of multivalent
anions. Polyaluminium chloride is in the form of golden yellow, khaki, brown, or
red granules/flakes. The water quality after purification is better than that of
aluminium sulfate coagulant, and the water purification cost is 15-30% lower
than that of aluminium sulfate coagulant. It has fast floc formation and
sedimentation speed, and has a greater processing capacity than traditional
products such as aluminium sulfate. It can consume water with alkalinity lower
than that of various inorganic coagulants, so no or less alkali agent can be
added. The applicable raw water PH range is 5.0-9.0. It has low corrosiveness,
good operating conditions, better solubility than aluminium sulfate, and better
applicability to source temperature than inorganic coagulants such as aluminium
sulfate.

Product Features
1. It has unique performance in treating papermaking and printing and dyeing wastewater.
2. It has fast flocculation and precipitation, and can increase production capacity by 1.5-3 times under corresponding conditions.
3. Under the same dosage, the hardness of water consumed during coagulation is less than that of various inorganic coagulants, and the pH value of treated water is also reduced less.
4. When treating high-concentration water, alkaline additives and organic coagulants can be added without or with less addition.
5. Its decolorization ability is better than other inorganic water purifiers.
