PAC & PAM Function During Filter Press Working
Generally speaking, in order to speed up the filter press process and reduce the water content, some chemicals are added. Commonly used are cationic polyacrylamide and polyaluminum chloride. The right amount of addition can play a role in binding the sludge and speed up the filter press process. According to the different filter presses used, the dosage of chemicals is also different. For example, the belt filter press adds more chemicals, and the plate and frame filter presses add less chemicals.
Polyaluminum chloride (PAC for short, usually also called water purifying agent or coagulant) has a high degree of electrical neutralization and bridging effect on colloids and particulates in water, and can strongly remove micro-toxic substances and heavy metal ions, with stable properties.
Polyacrylamide (PAM for short, also divided into anion (HPAM) cation (CPAM), non-ionic (NPAM) is a linear polymer, is one of the most widely used water-soluble polymer compounds, polypropylene. Amide and its derivatives can be used as effective flocculants, thickeners, paper strengtheners and liquid drag reducers, etc., and are widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, textile, construction and other industrial sectors)
As for how much to add, add PAC or PAM or both. This requires the pharmaceutical manufacturer to combine with the water sample after the experiment. Proper use of the pharmaceutical will directly affect the filtration efficiency of chamber filter press.
