Light yellow PAC Polyaluminium Chloride Chemical Auxiliary Agent for Water Treatment
1.LANSEN PAC is Polyaluminum Chloride of spray drying type, pale yellow powder, used for drinking water treatment and paper mills as retention agent, work as coagulant for water treatment. It is made by purity raw materials of Al(OH)3. Food grade.
2.Polyaluminium Chloride / PAC is effective primary inorganic coagulant based on trivalent Al2+, excellent for drinking water production, wastewater treatment, as well as swimming pool treatment.
3.Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule, brings higher performance than traditional coagulants.
4.The wide applicable range of PH value, good effect in purifying the river water with algae, low temperature, and low turbidity, and slightly contaminated and better effect in purifying the high turbidity river water.
PAC's can offer a number of advantages over traditional coagulants such as alum or iron salts. Because PAC's are pre-neutralized and have a higher charge density than traditional coagulants, they coagulate via a more efficient mechanism, called charge neutralization. This allows PAC's to be effective at lower doses than alum or iron salts, when one compares the actual metal being added by the coagulant to the system.
- Can be used widely as coagulant for industrial and potable application.
- Easily soluble in water, dissolves rapidly.
- Cost is low, very competitive than other general coagulants
- Floc forming fast, good activity, good filtering.
- Dont need adding alkaline additives,if deliquescence, its effect remain same.
- Adapted for a wide pH value, strong adaptability
- The Salt content in the effluent will be reduced after use PAC.
- Can remove the water pollution of heavy metals and radioactive substances.
