Applicable methods of polyaluminum chloride

Polyaluminum chloride (PAC), an English term and Chinese abbreviation, is a water-soluble inorganic polymer with a variety of appearances, including white, light yellow, golden yellow, earthy yellow, brown, red granular / sheet, etc. The product has strong adsorption performance, and physical and chemical actions such as condensation, adsorption and precipitation occur in the hydrolysis process. The application effect in water treatment or other places is very good, the price is not high, the function is powerful, and it is non corrosive to the pipeline. Polyaluminum chloride can play a better role, not only because of the product, but also because of the correct use method and the preparation according to the reasonable proportion. In order to achieve the rapid dissolution of polyaluminum chloride, the following is to explain the applicable methods of polyaluminum chloride:

1、 According to the different conditions of raw water, a small test can be conducted before use to obtain the best dosage. Polyaluminum chloride is an inorganic high molecular compound, which is soluble in water and has certain corrosivity. According to the different conditions of raw water quality, a small test should be conducted before use to obtain the best dosage.

2、 For the convenience of calculation, the small-scale test solution is configured according to the weight volume ratio (w/v), which is generally 2 ~ 5%. If 3% solution is prepared: weigh pac3g, put it into a 200ml measuring cylinder, add about 50ml of clean water, dilute it to 100ml scale with water after dissolution, and shake it well.

3、 When using and preparing, mix and dissolve the solid: clean water =1:5 (w/v), and then add water to dilute to a solution of 2 ~ 3% (w/v). Less than 1% solution is easy to hydrolyze, which will reduce the use effect. Too high concentration is easy to cause waste.

4、 Add the medicine according to the best dosage obtained; The added medicine must be antiseptic.

5、 Pay attention to observation and adjustment during operation. If there is less alum flower and large residual turbidity in the sedimentation tank, the dosage is too small. If there is large and upturned alum flower and high residual turbidity in the sedimentation tank, the dosage is too large, which should be adjusted appropriately.

6、 When in use, liquid products are prepared into 5-10% water solution, and solid polyaluminum chloride products are prepared into 3-5% water solution (calculated by commodity weight);

7、 Pay attention to observation and adjustment during operation. If there is less alum and large residual turbidity in the sedimentation tank, the dosage is too small; If the alum in the sedimentation tank is large and overturned, and the residual turbidity is high, the dosage is too large, and it should be adjusted appropriately to achieve the best state.

8、 Less than 1% solution is easy to hydrolyze, which will reduce the use effect of polyaluminum chloride. Too high concentration is easy to cause waste, and it is not easy to control the dosage.
