As pretreatment: It is usually the pretreatment or biochemical post-treatment link in the entire leachate treatment process (such as: pretreatment + biochemical treatment + advanced treatment), aiming to reduce the load of subsequent treatment units (especially membrane treatment or biological treatment), prevent clogging, and improve overall treatment efficiency.As pretreatment: It is usually the pretreatment or biochemical post-treatment link in the entire leachate treatment process (such as: pretreatment + biochemical treatment + advanced treatment), aiming to reduce the load of subsequent treatment units (especially membrane treatment or biological treatment), prevent clogging, and improve overall treatment efficiency.

Select PAM type:Select PAM type:

Cationic PAM: The most commonly used type for treating landfill leachate. Pro quod particulae colloidales in leachate normale negativa charged sunt, PAM cationic potest cargas eorum neutralizare et effectum fortem bridgendum exercere. Ioniscitas (densitate charge) consideranda est. The more complex the leachate water quality and the higher the colloid concentration, the more cationic PAM with higher ionicity is usually required.Cationic PAM: The most commonly used type for treating landfill leachate.

Ioniscitas (densitate charge) consideranda est. The more complex the leachate water quality and the higher the colloid concentration, the more cationic PAM with higher ionicity is usually required.

Anionic PAM: It may be used when the leachate mainly contains positively charged solids (such as certain metal hydroxides), or it may be added after the positively charged floc formed by inorganic coagulants (such as PAC, PFS) to use its long chains for bridging.

Aplicatio notas:Aplicatio notas:

Use with inorganic coagulants: PAM is usually not used alone, but in conjunction with inorganic coagulants (such as polyaluminum chloride, polyferric sulfate, ferrous sulfate, etc.). In general, inorganic coagulant is added first for charge neutralization and preliminary flocculation, and then PAM is added for bridging to form large and dense alum flowers. The order and interval of dosing are important.Use with inorganic coagulants: PAM is usually not used alone, but in conjunction with inorganic coagulants (such as polyaluminum chloride, polyferric sulfate, ferrous sulfate, etc.).
