Poly aluminium Chloride is short for PAC, is a new highly efficient inorganic polymer flocculat, it is between ALCL3 and AL (OH) 3 between the hydrolysis product, by hydroxyl and bridging polymer, its molecular formula: [Al2 ( OH) nCl6-n • xH2o] m (m ≤ 10, n = 1 ~ 5)
PAC soluble in water easily, there is a strong bridge adsorption, in the hydrolysis process, accompanied by the electrochemical, cohesion, adsorption and precipitation and other physical and chemical changes. The product is mainly used for drinking water purification and industrial wastewater treatment, such as radioactive substances, lead (Pb + +) chromium (Cr + + +) highly toxic heavy metals and fluorine (F) water and so on. In addition, in precision casting, papermaking, leather, etc. are also widely
When dealing with drinking water, plus the general liquid dosage 5-30g/m3, plus solid dosage 1-15g/m3 treatment of domestic sewage and industrial wastewater, generally increase the liquid dosage 20-100 g/m3, solid increase dosage 10-50g/m3, water use should be based on the COD, PH, SS and other indicators. By testing to determine the appropriate dosage increase.
.Liquid the poly aluminium chloride Uses the polyethylene plastic barrel packing, each barrel only heavy 25kg, 50kg or 200kg. Uses the double-decked bung, Insidecovers buckles strictly, Outsidecovers tightens. When the user needs, the liquid gathers the aluminum chloride also serviceable stores the tanker ships. Solid product with double-decked packed in bags, each bag of only heavy 25kg, the inner layer is the plastic bag, outside the level weaves the bag for the plastic. This product should store up in ventilates in the dry storehouse, strictly prohibits the rain drenching, being affected with damp.
