Select the right aluminum chloride can achieve a multiplier effect
Poly aluminum chloride water purification agent production process nothing less than three, is the drum, frame-type and spray-dried polyaluminum chloride. Spray-dried polyaluminum chloride in the high content of aluminum, water-insoluble low, so the dissolution rate. Used for drinking water and higher standards of water treatment. The plate-type aluminum chloride in high aluminum content, low water-insoluble matter, Gu makes it mostly used for sewage treatment and drinking treatment. Aluminum drum aluminum content in general, high water-insoluble, Gu and more for sewage treatment. This is divided from the production process, according to the scope and content can also be used to carry out the division. Polyaluminum chloride flocculation and flocculation speed under different conditions will be completely different, then how can we improve the use of polyaluminum chloride? 1, the direct filtration process as a more traditional way to simplify The water treatment process is cost-effective. 2, in order to make direct filtration to obtain good results, the appropriate dosage of coagulant before filtering aluminum chloride to improve colloidal surface properties is necessary; and coagulant dosage can be reduced by 40% to 50% than the traditional process . 3, the use of polyaluminum chloride as coagulant, the following factors on the effluent turbidity indicators in order of magnitude: coagulant dosage, filtration rate, coagulant dosage and water turbidity. The impact on the total head loss index in order of magnitude: coagulant dosage, coagulant dosage, water turbidity and filtration rate. Polyaluminum chloride flocculation effect is good or bad also need you to choose a good quality product at the same time, there is a good process design, so that you can make the sewage treatment to achieve a multiplier effect.
It is not a dangerous item, except that it has a lot of heat released (dissolved heat) when it comes in contact with water when its package is broken.

Aluminum ions will follow the ions in the water to generate water-insoluble substances that will adsorb impurities in the water and make the water clear!
Then add water polymerization, and then by curing, may be due to the nature of the water can not be used in combination with the weak cationic polyacrylamide or
Because PAC itself is a flocculant flocculant, customers use polyaluminium chloride is to reduce the COD in the sewage, BOD, how to increase, then how to deal w
