Application
1. Water Deputation: Domestic and industrial water
2. Municipal wastewater treatment.
3. Treatment of industrial wastewater, sewage, sludge and recovery of certain residues in sewage, etc.
4. For some industrial wastewater that is difficult to treat, PAC is used as the matrix, and other chemicals are mixed into the compound PAC. The wastewater can be treated with a surprising result.
Features
1. High Al2O3 content, No less than 29.5%.
2. Low salinity, only 50%, low than ordinary PAC(80%).
3. The water insoluble matter is low than ordinary PAC(1.5%).
4. Pure with extremely low content of other heavy metals except aluminum. It is clear and transparent when dissolved in water, But the ordinary PAC appears yellow or brown after dissolved in water.
5. Low Fe content, easily soluble in water at low temperature.
6. The scope of application is small and the cost is high in water treatment.

Application
Domestic water, urban water supply and drainage, drinking water.
Features
1. Wide application range and wide adaptability to water
2. Floc formation is fast, good activity, good filterability.
3. The suitable pH range is wide (between 5 and 9), and the pH and alkalinity of the treated water decreases little.
4. Alkalinity is higher than other aluminum and iron salts, easily soluble in water, easy to use, and stable in quality
5. Less salt in treated water, conducive to ion exchange treatment and high purity water making.
6. COD removal effect is good.
7. High active ingredient.
Shelf Life
Two years. It can still be used after Damp.

Application
Mainly used for the purification of domestic drinking water and the treatment of industrial wastewater, special water quality (such as oily wastewater, printing and dyeing papermaking wastewater, wastewater treatment, smelting wastewater, radioactive substances, toxic heavy metals such as Pb, Cr and fluorine-containing wastewater, etc.) Drilling, tanning, metallurgy, papermaking and other industries.
Features
1. Wide application range and wide adaptability to water
2. The flocculation and sedimentation speed is fast, and excessive addition will not cause water turbidity. When the water temperature is low, the stable coagulation effect can still be maintained
3. The suitable pH range is wide (between 5 and 9), and the pH and alkalinity of the treated water decreases little.
4. Alkalinity is higher than other aluminum and iron salts, easily soluble in water, easy to use, and stable in quality
5. It can form flocs quickly, and has large alum blooms and rapid settling speed. It is suitable for water sources of various temperatures and has good solubility.
6. COD removal effect is good.
7. Cost is 20 ~ 80% lower than other inorganic coagulants.
Shelf Life
Two years. It can still be used after Damp.
Package
25kg/bag, external plastic woven bag with plastic film inside, or as your requirements.
Notes
1. This product is acidic, prohibited to store it with alkaline substances (such as bleach, lime, etc.), otherwise the product will fail.
2. Protect from rain and sun, should be stored in a dry , ventilated and cool place place.
3. This product is forbidden to be mixed, transported and stored with toxic substances.
Usage
Dissolved into solution by add water at a ratio of 1:3, then add 10-30 times more water to dilute to the required concentration. Choosing the best pH value to add can bring the big benefit of coagulation, usually the best PH is 3.5-5. Dosage is 0.5-2.0kg (5-20ppm) per 100 tons of turbid water, When the turbidity of the raw water is high, the dosage is appropriately increased, and when the turbidity is low, the dosage can be appropriately reduced.
Usage Notice
1. Do test at first, choose the best value based on water quality.
2. Water treatment agents from different manufacturers and brands cannot be mixed.
3. Stock solution and diluent are slightly corrosive, but lower than other inorganic flocculants.
