1, the coal preparation plant selects polyacrylamide to carry on the coal slurry precipitates to concentrate the tailings to filter, please use anionic polyacrylamide, non ionic polyacrylamide, low cationic polyacrylamide.
     2, paint industry wastewater please use anionic polyacrylamide, non-ionic polyacrylamide. For paint wastewater treatment, the traditional method is to coagulate the mixed wastewater directly. The treatment effect is not satisfactory. The quality of the effluent is unstable and the discharge standard is hard to meet.
     3, biological wastewater treatment of dairy products, sludge treatment, select cationic polyacrylamide.
     4, electroplating wastewater containing cyanide treatment of anionic polyacrylamide, non-ionic polyacrylamide, low cationic polyacrylamide.
     5, copper mining tailings wastewater treatment of anionic polyacrylamide, low cationic polyacrylamide, non-ionic polyacrylamide.
