Product Introduction

Drinking water grade polyaluminium chloride is a yellowish-brown liquid or yellow granular powder solid. The product indicators comply with the national standard GB15892-2020 "Polyaluminium Chloride for Drinking Water". It is produced using domestically advanced spray drying technology, and the product features fine powder, uniform particles, easy solubility in water, good flocculation effect, high purification efficiency and stability, low dosage, and low cost.Drinking water grade polyaluminium chloride has high purity, low instant and low water insoluble matter. The color of the product is reddish brown, light yellow and white. This product has high aluminum content and low water insoluble matter. It is mainly used for drinking water treatment and sewage treatment. This product is used as a water purifier mainly has the following characteristics:

1. Polyaluminum chloride has large molecular structure, strong adsorption capacity, low dosage and low processing cost.

2. Good solubility, high activity, large alum blooms formed by agglomeration in the water body, rapid sedimentation, and 2-3 times greater purification capacity than other inorganic flocculants.

3. Strong adaptability, little affected by the pH value and temperature of the water body, source water in the range of PH5.0-9.0 can be condensed. After purification, the raw water reaches the national water standard, and the treated water has low cation and anion content, which is beneficial to ion exchange treatment and the preparation of high-purity water.

4. Low corrosiveness and easy operation, which can improve the labor intensity and working conditions of the dosing process.

5. The purified water quality is better than aluminum sulfate flocculant, and the water purification cost is 15-30% lower than that.

6. The alkalinity of the consumed water is lower than that of various inorganic flocculants, so no or less alkalis can be used.

7. The solubility is better than aluminum sulfate.

8. The salt in the treated water has little increase, which is beneficial to ion exchange treatment and high-purity water production.

Product Usage

This product is widely used in the production and use of low temperature and high turbidity water purification, industrial water supply, waste water and sewage purification treatment. It is suitable for removing colloidal suspended solids in wastewater, such as tap water, paper, thermoelectric, chemical, pharmaceutical, mining, food, steel, mineral processing and tannery, except for COD, BOD and decolorization and chemical additives industry.

Usage and dosage

1. the solid product and normal temperature water by 1: 2.5-1: 3 (weight ratio) mixed for about 30 minutes, the drug is completely dissolved, add 30-40 times the water diluted to the required concentration after use (source water turbidity The greater the secondary dilution plus the more water).

2. source water turbidity in the 100-500mg / L, the dosage for the amount of water per kilowatt of 5-10Kg. It is advisable to make a small test based on the water quality characteristics before use to determine the optimal dosage.

3. the best effect of poly aluminum chloride PH value of 7-9. Water temperature is too low affect the product flocculation effect.

Packaging and storage

1.using lined with polyethylene film, jacket polypropylene plastic woven bag double packing, 25kg / bag.

2.stored in a cool dry and ventilated place, the solid shelf life of 12 months.

Polyferric sulfate is a high molecular flocculant with excellent performance. Its morphology is light yellow amorphous powdery solid, easily soluble in water, and a 10% (mass) aqueous solution is a reddish brown transparent solution, hygroscopic. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dehydration, etc. Polyferric sulfate has excellent performance, dense alum flowers, and fast sedimentation speed, which can be completed in 5-30 minutes. The effluent water quality is good, and there is no water phase transfer of iron ions even if it is 10 times excessive, and the water will not turn yellow. Its performance is stable, and it can still be stored for a long time after dissolution, without precipitation, deterioration, and will not block the pipeline. It has many functions such as significant decolorization, deodorization, dehydration, degreasing, sterilization, removal of heavy metal ions, radioactive substances and carcinogens in water, and has a strong ability to remove COD and BOD. It is suitable for water bodies with a pH

range of 4-11, and has unique effects on the purification of micro-polluted, algae-containing, low-temperature and low-turbidity source water, and is less corrosive to pipeline equipment.
