Correctly configuring the amount of polyaluminium chloride can achieve twice the result with half the effort, because the properties of polyaluminium chloride include physical and chemical properties, so when adding polyaluminium chloride, it is necessary to achieve the best flocculant effect and economic benefits. Users can determine the best dosage per thousand tons of water through experiments according to different source water turbidity, different seasons and different reaction conditions. Today, Yili's editor shares with you a method that can quickly determine how much polyaluminium chloride is suitable to be added when the sewage treatment plant purifies sewage, so as to achieve the best purification effect.
1. According to the different conditions of the raw water, a small test can be done before use to obtain the best dosage. For the convenience of calculation, the small test solution is prepared according to the weight ratio (W/W), generally 2-5% is better. For example, to prepare a 3% solution: weigh 3g of polyaluminum chloride solid, put it into a clean 200ml measuring cylinder, add about 50ml of clean water, and dilute it to 100ml scale after dissolving, and shake it well.
2. For production, mix and dissolve according to the weight ratio of polyaluminum chloride solid: clean water = 1:9 to 1:15 (liquid products use 1:2 to 1:5). Solutions with an aluminum oxide content of less than 1% are easily hydrolyzed, which will reduce the use effect. If the concentration is too high, it is not easy to add uniformly.
3. Add the best dosage obtained in the small test, and pay attention to observation and adjustment during operation. If there are few alum flowers in the sedimentation tank and the residual turbidity is large, the dosage is too small; if the alum in the sedimentation tank is large and flipped up, and the residual turbidity is high, the dosage is too large and should be adjusted appropriately.
Polyaluminium chloride is used in daily drinking water, industrial water, domestic water, domestic sewage and industrial sewage treatment, and has a significant effect on the purification of daily drinking water and various industrial water. Especially in some cities with more rain, it solves the problems of sedimentation speed and water bloom in the treatment of low turbidity urban sewage. As long as the amount of polyaluminium chloride is controlled, its sewage treatment effect will be better.
