 Polyaluminium Chloride
Polyaluminium Chloride referred to as PAC, is a kind of more hydroxyl.Solid product appearance for light yellow or red and yellow powder, its molecules for [AL2 (OH) nCL6 - n] m, n acuities 5 m more than 10. Because of molecular contains quantity of hydroxyl,as Polyaluminium Chloride joining with muddy water, after the PH conditions continue to hydrolysis, in hydrolysis, along with the condensation, adsorption, the precipitation and so on a series of chemical process, thus achieved the purification purpose.
The evident marked of this product is water purification effects, more flocculating sedimentation velocity, adapt PH range wide, low corrosive to the pipeline equipment, can effectively remove the water color qualitative SS, COD, BOD and arsenic, lead, mercury and other heavy metal ions,low cost in water making, as big effectiveness,small dosage, simple operation, save manpower and material resources.
- floc forming fast, good active and used widely.
- Dont need add alkaline additives, such as the case of air-slake,the effect is unchanged.
- Adapt wide PH range, strong adaptability and used widely.
- Less salt in treated water .
- Can remove heavy metal and radioactive substances in water pollution.
- High effective ingredients, facilitate storage and transportation.
product usage
Polyaluminium can eliminate bacterium, deodorant, decoloring, fluoride, aluminum, chromium, phenol, remove grease, scavenging turbidity stains, remove heavy metal salt, remove radioactive pollution, especially for purification of various water for a wide range of applications.
- Purification living and drinking water, life sewage.
- Purification industrial water, industrial waste water, mining, oilfield waterflooding, purify the papermaking, return of metallurgy, coal washing, leather and all kinds of chemical pollution treatment, etc.
- Industrial production application: paper glue, dyeing and printing dyeing, cement herein, precision casting stiffening agent, refractories adhesives, glycerin refined, sugar liquid refining, the cloth anti-creasing, medicine, cosmetics, etc and other industries, wastewater recycling.
- In oil refining industry, used for water-oil separation, the effect is really good.
