Polyaluminium Chloride Powder Poly Aluminium Chloride In Water Treatment
Spray-dried polyaluminum chloride products have good stability, adapt to wide water areas, fast hydrolysis, strong adsorption capacity, large alum blooms, fast dense precipitation, low turbidity of the effluent, good dehydration performance, etc., under the same water quality. , The spray-dried product dosage is reduced, especially in the case of poor water quality, the spray-dried product dosage can be reduced by half compared with the drum-dried product, which not only reduces the labor intensity of the workers, but more importantly reduces the user’s system Water cost. In addition, spray-dried products can ensure safety, reduce water accidents, and are very safe and reliable for residents' drinking water. Spray-type polyaluminum chloride is a new process product of polyaluminum chloride. The acidity of spray-type polyaluminum chloride is lower than other inorganic flocculants.
|Basicity of salt||40-90%|
|PH (1%water solution)||3.5-5|
1. According to the different conditions of the raw water, you can do a small test to get a better dose before use. For the convenience of calculation, the small test solution is configured according to the weight ratio (W/W), generally 2 to 5% is better. For a 3% solution: weigh 3g of polyaluminum chloride solid, put it into a washed 200ml measuring cylinder, add about 50ml of clean water, and then add water to dilute it to the 100ml mark after dissolving, and shake it well.
2. For production, mix and dissolve according to the weight ratio of polyaluminum chloride solid: clear water = 1:9 to 1:15 (liquid products use 1:2 to 1:5). A solution with an alumina content of less than 1% is easy to hydrolyze, which will reduce the use effect, and the concentration is too high to be uniformly dosed.
3. Add the medicine according to the better dosage obtained from the small test, and pay attention to the adjustment during operation. If you see that the sedimentation tank has little alum blooming and the residual turbidity is large, the dosage is too small; if the sedimentation tank is large and upturned, and the residual turbidity is high, the dosage is too large and should be adjusted appropriately.
4. Dosing facilities should be antiseptic. This product is suitable for all water treatment facilities.
