Polyaluminum chloride is an inorganic polymer coagulant, also referred to as polyaluminum chloride or polyaluminum, and the English abbreviation is PAC. It is produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions. Inorganic polymer water treatment agent with larger molecular weight and higher electric charge. In terms of form, it can be divided into solid and liquid, and solid is divided into tan, yellow and white according to different colors. Polyaluminum chloride of different colors also has great differences in application and production technology.
chemical properties
It has the properties of adsorption, agglomeration and precipitation, and the stability of polyaluminum chloride is poor. Toxicity and protection are corrosive, if accidentally splashed on the skin, rinse immediately with water. Production staff should wear overalls, masks, gloves, and long rubber boots. The production equipment should be closed, and the workshop should be well ventilated.
Polyaluminum chloride PAC concentration ratio method:
According to the daily use of solid polyaluminum chloride PAC, when diluting it into liquid, summarize and share several commonly used polyaluminum chloride PAC concentration ratio methods, hoping to help everyone!
The first step is to do a small test to obtain the best dosage according to the raw water condition. The configuration of the small test solution is generally 2 to 5% by weight. For example, with 3% solution: weigh 3g of polyaluminum chloride PAC solid, put it into a 200ml graduated cylinder, add about 50ml of water, after dissolving, add water to dilute to 100ml scale, and shake well.
In the second step, when producing polyaluminum chloride PAC, it can be mixed and dissolved according to the weight ratio of polyaluminum chloride PAC solid: water = 1:9 to 1:15. The solution with alumina content less than 1% is easy to be hydrolyzed, which will reduce the use effect, and it is difficult to add evenly if the concentration is too high.
The third step is to add the medicine according to the optimal dosage obtained by the small test. If the alum in the sedimentation tank is small and the residual turbidity is large, the dosage is too small; if the alum in the sedimentation tank is large and turned up, and the residual turbidity is high, the dosage is too large and should be adjusted appropriately.
Water-insoluble matter of PAC polyaluminum chloride: Using plate and frame filter press technology, the mass fraction of solid water-insoluble matter is below 0.3%, and the mass fraction of liquid water-insoluble matter is below 0.1%, which can ensure the smooth flow of the user's pipeline. At the same time, the utilization rate of drugs can be improved, which cannot be achieved by the natural sedimentation method. Polyaluminum chloride PAC-01 (pale yellow powder, spray drying): used for drinking water treatment and wastewater treatment. Polyaluminum chloride - is one of the star products in the series of water treatment chemicals. Polyaluminum chloride integrates many advantages such as ordinary polyaluminum chloride, spray type polyaluminum chloride, and high-efficiency polyaluminum chloride for papermaking. Efficient product. All water treatment chemicals are subject to the latest national standard, and water treatment chemicals are subject to GB15892-2009.
Water treatment agent-high-efficiency polyaluminum chloride is the best water treatment agent for inorganic macromolecules in my country at present. The effect of treating water of various concentrations is quite good, and the dosage is small. Its dosage is 50% less than that of ferrous sulfate with the same concentration The same concentration of polyaluminum chloride uses 10% less. High effect and low energy are mainly due to the high degree of polymerization of PAFC, because the general iron salt and aluminum brine treatment agent can only generate AL(OH)2+, AL(OH)+2, Fe(OH)2+, Fe(OH)+2 and other simple hydrolyzed hydroxyl ions, while PAEC itself is AL3+, Fe3+ pre-aqueous product, it can generate a large amount of ionomerization degree in addition to the above-mentioned hydroxyl ions during the hydrolysis process. : Polyhydroxy cations such as AL4(OH)4+8, Fe4(OH)4+8, etc., to neutralize the charge of colloidal particles in water and compress the electric double layer. , under the corresponding collision, it condenses into large alum flowers and precipitates rapidly.
