First.The characteristics of the product

This product has strong bridging adsorption performance, during the hydrolysis process, accompanied by coagulation, adsorption and precipitation and other physical and chemical process. The fundamental difference between polymerization aluminum chloride and traditional inorganic coagulantsin the traditional inorganic coagulant for low molecular salt crystals, while the structure of polymeric aluminium chloride from multiple carboxyl complex changing patterns of composition, flocculation and sedimentation speed, wide applicable range of pH value, no corrosion to pipeline equipment, water purification effect is obvious, can effectively support in addition to water color quality of SS, COD, BODand arsenic, mercury and other heavy metal ions, the products are widely used in the field of drinking water, industrial water and wastewater treatment.

Three.The use of methods

The solid product dissolved in water according to 1:3 for the liquid, then with the 10-30 times of waterdiluted to the required concentration after use. The optimum pH and vote for 3.5-5.0, select the bestpH value adding, can maximize the effectiveness of coagulation. Dosage may be different according to the raw water turbidity, determination of optimal dosage, general turbidity of the water in the 100-500mg/L, the dosage for each 1000 tons of 10-20kg. When the water turbidity, coagulant dosageincreasing, turbidity is low, the dosage can be reduced.

 

Four.Packaging

The external plastic woven bag, a plastic film package, 25kg net weight of each bag, can be converted according to user requirements, otherwise the liquid polyaluminium chloride sales.

The ban, the mixed with toxic substances transportation and storage, the product should be stored in dry, ventilated, cool, and should not be affected with damp.

Be very careful of the loading and unloading of solid products, storage period of one year.

 

Five.The matters needing attention

1 "Use should first test according to the water quality, choose the good effect of water purification, put a small amount of the best point. The solution should be with the distribution with the use, non drinking water should be selected according to the actual situation of the amount of.

2 The use of solid when dissolved in water, to accompany with 10-25% solution, and then diluted with water to the desired concentration, dissolved in the water slowly at first feeding, and continue to stir.

3 The different manufacturers and different grades of water treatment chemicals should not be mixed,and not with other chemicals mixed.

4 The stock solution and diluted slightly corrosive, but lower than that of other kinds of inorganicflocculant.

5 The effective storage period of products: liquid solid two years half. Still can use solid products surge.

6 The this product by properly adding, purified water quality conforms to the sanitary standard for drinking water.
