PAC

Abbreviations: poly aluminum or PAC formula: [Al3 (OH) nCl6-n] m Appearance Form: light yellow amorphous powder. Packing: woven bag lined with plastic bags, 25Kg / bag. Technical indicators: compliance GB GB14592-95. Project PH value (1%) Al2O3 content% basicity% water insoluble% arsenic (As) ppm index 3.5 ~ 5.0 27 ~ 33 60 ~ 85 ≤0.5 ≤0.01 Project Mercury (Hg) ppm Cr6 + ppm of lead (Pb) ppm Cadmium (Cd) ppm manganese (Mn) ppm indicators ≤0.001 ≤0.005 ≤0.01 ≤0.01 ≤0.1 Applications: ⑴ purify drinking water and industrial water, municipal wastewater. ⑵ can be used for purification and dyeing, paper, leather, metals, food and other industrial wastewater. ⑶ can be used for precision casting, paper sizing precipitant. ⑷ can be used for sludge dewatering, refractory and ceramic binder. Features: poly aluminum belong aluminum-based inorganic polymer coagulant, accompanied by the electrochemical reaction takes place in the hydrolysis process, so that the water destabilization of colloidal particles, through bonding, bridging, adsorption flocculation with turbidity, bleaching, off the oil, remove organic matter and so on, to adapt to the water PH value range of 4 to 11, the best 6-8. Usage: ⑴ before using this product formulated with water into a 5 to 10% solution, stir to use. Depending on the amount of goods ⑵ local water quality, to determine the optimal dosage by small scale. ⑶ poly aluminum hygroscopic caking, pay attention to moisture during storage and transportation.
