Particularly fast in thin sheet

PAC can be used as coagulant for all types of water treatment, for example, drinking water, industrial waste water, urban waste water and in the paper industry.
For  river water, lake water and underground water
For  industry water and industry recycling water
For waste water
The purification of the waste water in printing and dyeing industry, leather industry, meat-processing industry, coal-washing, metallurgy industry, mine, pharmacy, paper-making, and the purification of the waste water containing fluorine, oil and heavy metals.
Dissolve the solid product into liquid in 1:3 with water, and then dilute it with 10-30 times of water to the required concentration. The best pH value for the addition is 3.5-5.0. The best pH value can bring the maximum benefit of coagulation. The dosage can be determined according to the different turbidity of raw water, Generally, when the turbidity of raw water is 100-500mg/L, the dosage per thousand tons is 10-20kg.. When the turbidity of the raw water is high, the dosage is appropriately increased, and when the turbidity is low, the dosage can be appropriately reduced.

For rural use, the medicine can be put into the water tank, stirred evenly, static, supernatant can be used, every 50 kg to add about l grams of this drug. If the agent is used in combination with a polymer flocculant produced by the company, the effect is better. The drug can be used to dissolve the anionic polyacrylamide or cationic polyacrylamide together with PAC into a composite flocculant or to add PAC to the treated water to form agglomerates, and then add the anionic polyacrylamide produced by the company to form a large flocculant for adsorption
The dosage of poly aluminium chloride in different water quality:
1 In low turbidity water, the solid poly aluminium chloride product is diluted in 1:3 ratio (weight ratio) with tap water and stirred until completely dissolved.
2. In the sewage for living and production, about 30g of poly aluminium chloride product added into per ton of sewage. Then add the diluted polyacrylamide product (if the effect is not obvious, please reduce or increase the product dosage as appropriate.)
3 In the paper mill waste water treatment, the proportion of low turbidity water is used. If the effect is not obvious, it can be added at the discretion.
4. When the raw water turbidity is 100-500mg/L, the dosage is 5-10mg, that is, 5-10kg per kiloton of water. It is best to carry out a small test according to the water quality characteristics before use, and select the best value, then invested.
