Focused on water treatment agents for over 60 years

Rational formula: Aln(OH)mCl3n-m     0<m<3n

Appearance: liquid colorless to light yellow transparent liquid; Solids are white to pale yellow particles or powders.

Nature: Polyaluminum chloride is an inorganic polymer polyelectrolyte coagulant with polyvalent ions. It is an intermediate hydrolysis product between aluminum trichloride and argon-alumina. Due to the bridging effect of oxychloride ions and the polymerization of polyvalent ions, inorganic polymer water treatment agents with larger molecular weight and higher charge are generated.

Purpose: River water, reservoir water, groundwater purification, industrial water purification, urban sewage treatment, sludge treatment, coal washing, paper sizing, cosmetic raw materials and catalytic carriers printing and dyeing, leather, wine, meat processing, mining, oil refining and heavy metal industry sewage treatment, high toxic heavy metal and fluorine sewage treatment.

Packaging: solid; Polyethylene coated bag, lining double woven packaging, each bag 25kg

Storage and transportation: liquid, should be lightly unloaded to avoid packaging damage, shall not be transported with harmful drugs, common storage. Dry at room temperature, liquid product storage period of six months. Use in sealed canned vehicles or plastic containers. Solid, should be lightly unloaded to avoid packaging damage, not with harmful drugs co-transport, co-storage.

Features: Stable chemical properties at room temperature, non-toxic and harmless, high water safety, fast reaction, less amount, alum formation fast and large, dense settlement fast, good filtration, can improve equipment utilization Low cost, low labor intensity suitable for raw water PH range, in the PH value 4-12 range can be coagulated, PH value 6-8 the best. It is suitable for the treatment of all kinds of water bodies, and the purification effect of high turbidity water is particularly obvious. Do not add alkalinity or other coagulants. It also solved the problem that other agents are not easy to treat low turbidity water and low temperature water (below 4 degrees) with poor reaction and slow effect. Good water solubility, excessive delivery will not cause side effects, easy to operate and manage, non-corrosive to water treatment equipment and pipelines.

Usage: According to the different conditions of raw water, the general water purification dosage: solid 3-30PPm liquid products 10-100ppm. Dosing according to the best dosage, and observe and adjust in use. If the settling tank alum flower is small, the remaining turbidity is large, the dosage is too small, if the settling tank alum flower is large and upturned, the remaining turbidity is high, the dosage is too large, should be adjusted appropriately.
