What is the difference between industrial grade and drinking water grade of polyaluminium chloride
Summary:
The low-level difference between industrial polyaluminum chloride and drinking water grade polyaluminum chloride depends on the scale of use, and the product target requirements are different. The specifications of water insoluble substances and aluminum chloride content of industrial polyaluminum chloride are lower than the requirements of drinking water grade polyaluminum chloride. The requirements of drinking water grade polyaluminum chloride and heavy metal content used in water plants in China are relatively strict (the visual capacity GB15892-2009 the national specifications of drinking water grade polyaluminum chloride).
Polyaluminum chloride can be divided into two categories: industrial grade and drinking water grade

Industrial Polyaluminium Chloride
Industrial polyaluminum chloride is an inorganic polymer flocculant. It is a new type of water treatment agent developed on the basis of traditional aluminum salt and iron salt. Polymeric aluminum chloride (PAC) has good coagulation performance, which is suitable for large alum, small dosage, high efficiency, fast sedimentation and high water quality. Mainly used for industrial wastewater purification. In addition, it can also be used to remove heavy metals such as iron, manganese, chromium, lead, fluoride and water oil contained in water. The treatment scale includes paper mill sewage treatment, steel mill sewage treatment, domestic sewage treatment, printing and dyeing mill sewage treatment, Oilfield sewage treatment, etc. Industrial grade polyaluminum chloride is mainly used for roller type, brown or dark yellow product shape.
Industrial Polyaluminum Chloride Manufacturers
Industrial Polyaluminium Chloridealuminum use scale:
1) It can be used for the treatment of rivers, lakes, groundwater, industrial water and industrial circulating water.
2) It can be used for the recovery of coal mine refining wastewater and ceramic industrial wastewater.
3) It can be used in printing plants, printing and dyeing plants, leather factories, breweries, meat processing plants, pharmaceutical factories, paper mills, coal washing, metallurgy, mining areas and fluorine, oil, and heavy metal wastewater treatment.
4) It can be used for anti-wrinkle of leather and cloth. It can be used as an excellent catalyst.
5) It can be used for cement setting and molding casting. Properties of drugs, glycerine and carbohydrates; binding of paper.
POLYALUMINUM CHLORIDE DRINKING WATER GRADE
Drinking water grade polyaluminum chloride is a new type of inorganic polymer water, which can be mainly used in frame filter press or spray odorless type, showing yellow, light yellow or golden yellow. Generally, it has more than 29% aluminum dioxide content, low quality and low price. It is a new, efficient and safe detergent widely used in tap water and drinking water recycling.
Use of drinking water grade polyaluminium chloride
1. The solid product is boiled in 1:3 water, dissolved into a liquid, then 10-30 times of water is added, diluted to the desired concentration and used.
2. The best dosage can be measured according to the different turbidity of raw water. Generally, the turbidity of raw water is 100-500mg/L and 10-20kg per thousand tons.
3. Polyaluminum chloride storage method: this product should be stored in the dry, moisture, heat, storage and transportation to avoid toxic substances pollution and heat and moisture, do not damage the packaging.
4. Polyaluminum chloride packaging specification: product selection of non-toxic polyethylene plastic bags and woven bags, each bag of wool weight: 25kg.
The basic difference between industrial-grade polyaluminum chloride and drinking water-grade polyaluminum chloride is that industrial polyaluminum chloride is not too picky about heavy metals, salt and water insolubility, but these three goals of drinking fountains must be strictly in accordance with national drinking water Safety regulations are implemented.
