                                                             PAC Polyaluminium chloride

I. Main characteristics:

Compared with other coagulants, this product has the following strong points:

1, Wide range of application.

2, Good settling behavior.

3, Wide range of suitable PH value(5-9).

4. Stable settling behavior can be kept when the water temperature is low.

5, Degree of alkalisation is higher than other aluminium salt,iron salt,small corrosion to equipment.

II. Technical index and use:

 According to the improvement of people's requirement on water quality, our company has developed polyaluminium oxide series products:polyaluminium chloride,aluminium chlor hydroxide,ferric chloride,aluminium sulphate,compound iron etc.. 

Polyaluminium chloride function:

Polyaluminium chloride molecular formula: [Al2(OH)nCL6-n] , basicity: B=n/6×100%,

so its flocculation function as follow:

a. water colloidal substance strong electric neutralization.

b.  hydrolysate suspended in water good bridging adsorption.

c.  on solubility material selective adsorption.

method of use:

1. When using a moderate amount of the product directly added in to deal with the water, and strong stirring the water and mix. 

2. Specific drug dosage and decide, depending on the source water with beaker on flocculation test, determine the optimal drug dosage. 

polyaluminium chloride application fields:

1, water purification treatment: the water for living, industrial water;

2, urban sewage treatment;

3, industrial wastewater, sewage and sludge treatment and some of sewage sludge mass recovery, etc.;

4, for some processing difficulty big industrial sewage to PAC for maternal, adding the [1] he agent, allocate composite PAC, sewage can get surprise effect.

Polyaluminium chloride performance features:

1, polyaluminium chloride molecular structure, adsorption ability, consumption, dealing with low cost.

2, good solubility, high activity, in the water condensed formation of alum flowers, settling quickly, than the other inorganic flocculant purification capacity of 2-3 times.

3, strong adaptability, the water PH value and temperature effect is small, the raw water after purification reach national drinking water standard, the water quality after treatment ZhongYang anion content low, which is helpful for ion exchange process and high pure water preparation.

4, corrosive small, simple operation, can improve the administration process of the intensity of labor and labor conditions spray drying polyaluminium chloride technical parameters:
