Description

PAC (Polyaluminium Chloride) abbreviate to the PAC. Often referred to aluminum chlorideor or mixing mud agent, which is a water-soluble inorganic polymers between ALCL3 and AL(OH) 3, the chemical formula is [AL2 (OH) NCL6- NLm] ,'m' refers to the extent of polymerization, 'n' stands for the neutral level of PAC products. The color often is yellow,light yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption properties, in the hydrolysis process, with the condensate, adsorption,precipitation processes and other physical and chemical.
The fundamental difference between PAC and the traditional inorganic coagulant is that traditional inorganic coagulant for the low molecular weight crystalline salt, and the structure of PAC is formed by complex multiple carboxyl,it has high speed of flocculation and sedimentation , for wide use of PH value, non-corrosive for plumbing, water purification effect is obvious, and can effectively support to clean the water-color quality SS, COD, BOD,arsenic, mercury and other heavy metal ions, which are widely used in drinking water, industrial water and wastewater treatment areas.
Usage : 　　
1, The solid product dissolved in water at 1:3 for the liquid, together with the diluted 10-30 times the required concentration of water before use.
2, The amount according to the different turbidity of the raw water, then determination of optimal dosage, when the general turbidity of the water in the 100-500mg / L, the dosing quantity of each dosage tons about 10-20kg.
Packaging and storage : 　　
1, Lined with plastic bags, with outer surface of plastic film woven bag, each bag weighs about 25kg. 　　
2, Stored in a cool and dry place to prevent the sun and rain.
