Aluminum chloride PAC PAC product properties Product Properties (basic aluminum chloride) referred to PAC or BAC, it is a new high polymer flocculant. It is between 3 product between AlCl3 and Al (OH), its main features are: 1. floc forming fast, good activity, good filtration. 2. No add alkaline additives. In case of deliquescence same effect. 3. adapt PH value width for wide waters, and versatile. The treated water, less salt. 5. Be able to remove heavy metals and radioactive substances to water pollution. Product use Product Useage can sterilization, deodorant, bleaching, fluoride, aluminum, chromium, phenol, oil, turbidity, in addition to heavy metal salts, with the exception of radioactive contaminants in water purification with a wide variety of uses, such as: 1 . purify drinking water, sewage. 2. industrial water purification, industrial wastewater, mining, oil field injection water, purification papermaking, metallurgy, coal washing, leather and various chemical industrial waste water and so on. 3. Industrial production applications: paper sizing, printing dyeing, quick-setting cement, precision casting sclerosis, but also for recycling refractories bond, glycerin refining, sugar refining, cloth wrinkle-free, pharmaceutical and cosmetics industries and wastewater use. 4. In the oil refining industry, for the oil-water separation.

Polypropylene amide molecule has a positive gene (-CONH2), with the decomposition of suspended particles in the solution adsorption and driving bridge, there is a strong flocculation, it is widely used in water treatment and metallurgy, paper, petroleum, chemical, textiles, mineral processing and other fields. Polypropylene amide into: cationic, anionic and nonionic. Product use Product Useage cation is mainly used for living and production water, industrial and urban sewage treatment. Also apply during the preparation of alumina flocculation of red mud and mud-liquid separation. Cationic high molecular weight, mainly used for suspension and flocculation of suspended matter cloud precipitation, the acid and acidic solution containing an organic flocculation of suspended matter is very difficult. In this case, cationic polypropylene amide can be effective for flocculation and sedimentation, indicating outstanding performance. 0.1-0.2% in water use form, must be formulated Ph≤7 of water, dubbed highly dilute solution hydrolysis. Should vary with the day spent with the use or not suitable for prolonged storage. 1. Advantages: PAM used for sewage treatment, high removal efficiency of organic compounds in water, with less settlement rate, low cost of water, flocculant can not be replaced by other products. 2. Usage: PAM used for water treatment can be used alone, it can be used in conjunction with PAC, but mixing the two must be kept separate, add water and the dosage size to determine the dilution according to their own circumstances. 3. This product lined with plastic bag, outer woven bag with plastic composite film bag, net weight 25 kg. 4. Pay attention to moisture, avoid the packaging is damaged, should be stored in clean and dry environment.
