Polyaluminium chloride
Author: Tianhe chemical sources: original date:2012-04-11

I. Introduction
Product name: Polyaluminium chloride, abbreviation is PAC.
Technical standard: Product quality comply with national GB15892-2009 standard
Product color: Golden yellow, reddish-brown, white.
CAS No.: 1327-41-9; EINECS No.: 215-477-2
Molecular formula: Al2Cl(OH)5; Molecular weight: 174.45

II. Features
1. Fast floc forming, high activity, good filtration.
2. No need of alkaline additive. In case of deliquescence, the effect remains unchanged.
3. Wide applicapable PH range, strong adaptability, wide use.
4. Low salinity in treated water.
5. Can remove the contamination of heavy metal and radioactive substance to water.

III. Use
1. Purify drinking water, sewage.
2. Purify industrial water, industrial wastewater, mining and oil field injection water, water generation, metallurgy, coal washing, leather and various chemical wastewater treatment, etc.
3. Industrial production applications: Paper sizing, printing, dyeing and bleaching, cement accelerating agent, precision casting hardener, refractory adhesive, fabric wrinkle-free, medicine and other industries. The wastewater can be reused.
4. In artificial coal industry, used in coal-water seperation with good result.
5. Can produce different specifications of products according to customer needs.

V. Model and code
1. Industrial grade polyaluminium chloride--GYPAC.
2. Drinking water polyaluminium chloride--SPPAC.
3. High purity polyaluminium chloride--GCPAC.
4. Liquid polyaluminium chloride--ETPAC.

VI. Using method
1. Dissolve solid polyaluminium chloride in water as 1:3 to liquid, add 10-30 times of water to dilute to the required concentration for use.
2. The dosage is depending on the raw water turbidity. Generally, the raw water turbidity at 100-500mg/L, the dosage per 1,000 tons is 10-20kg.

VII. Packing and storage
1. Plastic film woven bag lined with plastic bag, 25kg/bag.
2. Stored in dry and cool place to avoid sunlight and rain. Do not pile up with flammable, explosive and radioactive substances or chemicals.
3. Moisture does not affect the result. But as far as possible do not let them become damp. It is easily dissolved when becoming damp.
