the application in wastewater treatment for anionic and cationic polyacrylamide:

In acidic or alkaline media are positive, it is usually lower than anionic or non-ionic polyacrylamide molecular weight, its cleaning sewage performance is mainly through charge neutralization. The function of this kind of flocculant is mainly flocculating with a negative charge, with turbidity removal, decolorization function. In liquor factory, gourmet drinks factory, sugar factory, meat products factory, beverage factory, printing and dyeing factory wastewater treatment with cationic polyacrylamide than anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt effect is several times or dozens of times higher, because this kind of wastewater is generally with negative charge
