PAC Water Purifier
Jun 16, 2017

PAC Water purifier

Polyaluminium chloride also known as basic aluminum chloride code PAC. Commonly known as a water purifying agent or coagulant, which is between the AlCl3 and Al (OH) 3 between a water-soluble inorganic polymer, the chemical formula [Al2 (OH) nCl6-n] m Where m represents the degree of polymerization and n represents the neutrality of the PAC product.

Poly aluminum chloride series of products are: drum drying of poly aluminum chloride, frame filter poly aluminum chloride, spray drying poly aluminum chloride, a new type of high efficiency white poly aluminum chloride and so on. Widely used in urban water supply, drainage and chemical, metallurgical, power, oil, printing and dyeing, paper, pharmaceutical, industrial wastewater treatment and other fields, is the best water purification flocculant and filter filler.

Polyaluminium chloride compared with other coagulants, has the following advantages: a wide range of applications, to adapt to a wide range of water. Easy to quickly form a large alum, precipitation performance. The optimum pH range is wide (5-9), and the pH and alkalinity of the treated water decrease. Water temperature is low, can still maintain a stable precipitation effect. Alkalinity than other aluminum salts, iron salts, the erosion of the device is small.

The product has a strong bridging adsorption performance, in the process of hydrolysis, accompanied by condensation, adsorption and precipitation and other physical and chemical processes. The basic difference between polyaluminum chloride and traditional inorganic coagulant is that the traditional inorganic coagulant is a low molecular crystal salt, and the structure of polyaluminum chloride is composed of polymorphic carboxyl complex, and the flocculation and sedimentation speed is fast. PH value range, the pipeline equipment is not corrosive, water purification effect is obvious, can effectively remove the water color, SS, COD, BOD and arsenic, mercury and other heavy metal ions, the product is widely used in drinking water, industrial water and sewage treatment field.

Technical standard editor

Product quality in line with national GB15892-2003 standards

Key Features Editor

The product is an inorganic polymer coagulant. Mainly through the compression of electric double layer, adsorption and neutralization, adsorption bridge, sediment trap and other mechanisms of action, so that the water suspended particles and colloidal ions destabilize, aggregation, flocculation, coagulation, precipitation, to achieve the effect of purification.

The nature of the editor

Liquid products are colorless, light yellow, light gray or tan transparent or translucent liquid, no precipitation. The solid product is white, light gray, light yellow or tan grain or powder. Products in the alumina content: liquid products> 8%, solid products for 20% -40%, alkalization degree of 70% -75%.

Use the method to edit

The product (solid) and normal temperature water by 1/3 of the weight ratio while stirring to add, to completely dissolved, then diluted with water to the required concentration of raw water concentration of 100 ~ 500mg / L when the dosage is 3 ~ 6mg / L. Specific dosing, water quality should be based on the water test, select the best dosage and then put on.
