Product description:
Polyaluminium chloride is a kind of high efficient inorganic polymer flocculant, which is a hydrolysis product between AlCl3 and Al(OH)3. In the process of hydrolysis, physical and chemical reactions such as electrochemistry, coagulation, adsorption and precipitation occur.
Guanghua PAC series of products include spray-dried powder, made of bauxite, hydrochloric acid and calcium aluminate powder, and other high purity products with aluminum hydroxide and hydrochloric acid as raw materials. They’ve been widely used in treatment and clarification of drinking water, urban water supply and drainage as well as industrial wastewater treatment at home and abroad.
Usage:
Dilute the powder into 10-20% aqueous solution. The dosage of this product depends on different features of raw water, i.e. turbidity, application purpose and purification equipment used. The best dosage has to be determined by lab test before large-scale application.
(Note: it is better to use up the diluted solution within 24 hours to avoid hydrolysis and ensure the effect.)
