Product Description
polyaluminium chloride is a kind of inorganic polymer coagulant. And it is a high inorganic polymer water treatment agent with large molecular weight and high charge produced by the bridging of hydroxide ion and polymerization of multivalent negative ion.
1. Property of polyaluminium chloride
1) higher quality and lower cost of water purification by the PAC than that by aluminum sulfate coagulant
2) fast formation of flocculating constituent and settling velocity
3) low consumption of alkalinity in water with no or less adding of alkaline agent
4) low corrosivity
5)wider range of adapting pH(5.0-9.0)
6) better solubility than aluminium sulfate
2. Use
1) purification of urban water supply and drainage
2) industrial water purification and treatment, including the printing and dyeing wastewater, paper-making wastewater, etc.
3) recycling of the useful material in the industrial waste water and residual
4) strengthening the settlement of powdered coal in the coal-washing wastewater
3. Usage
1) The dosage depends on the waster water to be treated. Generally, the dosage in the water purification is as follows: 5-100 g / ton for the liquid PAC and 20 - 25 kg / ton for the solid PAC (in terms of goods). The dosage can be decided by the jar test.
2) The preparation can be directly added into the water which is decided by the amount of PAC and water to be treated. And the mixture should be stirred evenly.
