Application fields of white polyaluminum chloride

White polyaluminum chloride(also known as spray drying Polyaluminum Chloride) is widely used in many fields because of its high purity and low impurity characteristics. The following are its core application scenarios and technical advantages:

Drinking water and Industrial Water treatment
1. high safety purification
2. white polyaluminum chloride does not contain heavy metal impurities, and the iron content is below 100ppm, which can meet the drinking water standard (gb15892-2009). The treated water quality is transparent without residue.
3. low temperature and efficient dissolution
4. it can still dissolve rapidly and form flocs in low temperature environment, which is suitable for water treatment in northern areas or in winter.
5. wide adaptability
6. it is applicable to groundwater, reservoir water, river water and other water sources, with a wide range of pH values (5.0-9.0), without additional adjustment of pH.

Industrial wastewater and special wastewater treatment
1. complex wastewater treatment
●  printing and dyeing wastewater: significant decolorization effect, which can remove more than 90% of chromaticity.
●  oily wastewater: efficient oil-water separation through charge neutralization.
●  heavy metal wastewater: adsorb harmful substances such as cadmium, chromium and fluorine to reduce pollution risk.
2. resource recycling
3. it is used for coal washing wastewater pulverized coal sedimentation and starch industrial starch recovery to improve resource utilization.

Core auxiliaries in paper industry
1. neutral sizing instead of aluminum sulfate
2. compared with aluminum sulfate, white polyaluminum chloride can be used in neutral environment to reduce equipment corrosion and the difficulty of white water treatment.
3. improve paper performance
Add calcium carbonate filler to reduce the cost and improve the whiteness and folding resistance of the paper.
enhanced retention and drainage, reduced fiber loss and improved production efficiency.

Fine chemicals and special industries
1. cosmetics and medicine
2. as a stabilizer or raw material, it is used in pharmaceutical refining and cosmetic formula to meet the demand of high purity.
3. precision casting
4. as a hardener, improve the casting accuracy and reduce impurity residue.
5. sugar industry
6. the decolorization and clarification efficiency is high, and the addition amount only needs 5-10ppm to achieve the effect of transparent sugar solution.

Innovative applications in other fields
1. radioactive pollution treatment
2. adsorb radioactive substances in water for purification of cooling water in nuclear power plant.
3. cement accelerator
4. accelerate the cement setting process and improve the construction efficiency
5. aquaculture purification
6. treat the water quality of the fishpond, reduce the turbidity and do not affect the transparency of the water body.

Summary of technical advantages
●  purity characteristics: Al ɑ o ₃ content ≥ 29.5%, basicity 50%-70%, water insoluble ≤ 0.3%.
●  environmental compatibility: good solubility at low temperature, low corrosiveness and high operation safety.
●  cost effectiveness: the dosage is only 1/3-1/2 of the traditional reagent, and the comprehensive treatment cost is reduced by 15%-30%.
