1, poly (a) mechanism of aluminum chloride
Poly (a) Aluminum chloride is an inorganic polymer coagulants, as the hydroxide ion and multi-role bridging the price of anionic polymerization and the production of larger molecular weight, charge higher inorganic polymer chemicals. Molecular Formula as follows: [FROM (OH) nCL6-n] (1-for 5.m n ≤ 10) basicity: B = n / 6 × 100%, and its role in coagulation performance are as follows:
A, colloidal substances in the water, and in the strong role.
B, the hydrolysis product of the fine suspended matter in water adsorption bridging role.
C, soluble substances on the selective adsorption.
Poly (a) chloride in the water is the main form of AL13O4 (OH) 247 +
2, poly (a) of aluminum chloride
A, purified water is better than aluminum sulfate coagulant, water purification low cost compared with 15-30%. B, floc formation faster velocity faster than traditional product such as aluminum sulfate large capacity. C, below the alkalinity of the water consumption of inorganic coagulants, which may or less voted for alkaline agent. D, the source of water to 9.0 of the open-PH5.0 rally. E, corrosive small, good operating condition. F, solubility than aluminum sulfate. G, with increased salinity of the water less conducive ion exchange process and high-purity water system. H, the source water temperature adaptability than aluminum sulfate, inorganic coagulants.
3, poly (a) the use of aluminum chloride
A, urban drainage purification: river water, reservoir water, groundwater, b, c industrial water purification, sewage treatment d urban, industrial wastewater and sludge material useful in the recovery and promoting coal washing wastewater in the coal settlement, starch recovery in the manufacturing sector starch e, industrial wastewater treatment: dyeing wastewater, leather wastewater, wastewater containing heavy metal wastewater, oily wastewater, wastewater recycled paper, coal washing wastewater, mine wastewater, wastewater Brewing, metallurgical wastewater, meat processing wastewater f, g sewage treatment, paper sizing h, i refined sugar, Casting forming j, k crease-resistant fabric, catalyst l, medicine Refining m, n quick-setting cement, cosmetics raw materials.
Use:
1, as volume increases for water and the treated different, generally for water purification and about: Liquid product 5-100 grams / ton, solid 2-30 grams / ton (of goods), through the beaker test decision.
2, can be prepared by adding water directly, can increase water quantity for water treatment and decision, after mixing with water evenly.
Note:
A different manufacturers or different brands of chemicals mix, and not mixed with other chemicals depositors.
2, and the diluted solution of slightly corrosive, but less than other types of inorganic coagulants.
Three product effective storage period: six months liquid, solid year. Wave after solid product can be used.
4, the product was reasonable for Canada, purified water meets drinking water health standards. |
