According to the different degrees of cation, the cationic
charge of polyacrylamide powder particles are applied to different
papermaking sewage flotation and sludge filtration. For the
solid-liquid separation of papermaking wastewater, cationic
polyacrylamide can effectively collect the solid content to form
large and strong floc which can achieve ideal air flotation and
sedimentation effect to ensure. The clarity of the filtrate.
For the sludge filter dehydration, cationic polyacrylamide can effectively help
form large and strong floc to remove water in the sludge and improve the
dryness of sludge residue.
The polyacrylamide powder particles with anionic charge is suitable for different papermaking sewage floatation solid-liquid
separation and sludge filtration dehydration according to the degree of hydrolysis.
Cationic and anionic flocculants and thus can be used in a wide pH range. It is suitable for the treatment of wastewater,
which is difficult for a single chargeable flocculant, especially in water-soluble dye wastewater decolorization.
