Poly Aluminium Chloride PAC is a kind of innocuous, insipidness and easy dissolve in water with appearance of white or light yellow or yellow colour lipidic from liquid and fine resin solid powder, solid product is easy adsorb damp when exposed in the air. Purposes Purification for the river, lakes and underground water which are supplies for the city.Purification for industry water and industry circulation water.Purification for city polluted water.Purification for the wasted and polluted water from industry of printing and dying, paper making, sugar refinery, leather, brewage, meat process, coal washing, smelt metal and pharmacy etc. as well as the polluted water containing fluorin, oil and heavy metal.To reclaim coal from the coal-washing polluted water and reclaim kaolin form pottery industry.Glycerin making, pharmacy, liquid sugar refined.Solidifing cement quickly, foundry and moulding.Tannage and cloth cocking-prevent.Raw material of cosmetic.Carrier of catalyzer.Transportation and storage Solid PAC is packed with PP woven outer bag and PP inner bag, 25kg net weight each; or plastic film outer bag, and PP inner bag, 20kg net weight each. Liquid PAC is packed in tank container or in drum according to the requirement of the customers.Period of validity of liquid PAC is one year and that of solid PAC is two year. Solid PAC should be stored in dry and aeration area, to avoid moisture if the products get damp, it would not influence use.Liquid product and its diluted solution are slightly corrosive, which should be stored in anticorrosive container.PAC should not be stored together with poisonous and corrosive products or other chemical products.Usage and attention item In order to achieve the best flocculation affect and economic benefit, we strongly suggest customers should make certain the best dosage through quantification test before using the products. The products should be dissolved and diluted before use which can improve the precision of dosage. When confecting the dissolution, different consistencies should be made certain according to different treated subjects. The general consistence is 1-5%.The idiographic dosage should be made certain according to different water. The following table can be consulted for the general dosage:River water(ppm)Industry cinculation water(ppm)Living polluted water(ppm)Industrial polluted water(ppm)Paper making glue(%)Drought periodFiood periodDosage 5-1020-10010-5020-200200-5002-3 3. To avoid use the product together with others. Water treatments products. 4. Light calefation happens when solid PAC dissolves, but it will not influence the dissolutions and usage.
