ARK Powdered polymer flocculants Overview

The powdered polymer flocculants (DamoaTM) supplied from ARK to the customers are synthesized in the high-tech factories in South Korea/Japan.
Type Powder
Lineups Anionic PAM (A1110), cationic PAM (C1492)
Pros Large floc formation, ease of storage at the factories/treatment plants
Both anionic PAM (A1110 series) and cationic PAM (C1492 series) are delivered to the customers in powders.
The powdered PAM can be stored in a room for a long period of time when the chemicals are placed in a dry environment.
Note that humidity accelerates a depolymerization (hydrolysis) of the polymers, which results in deterioration of flocculation.

FREETA-α

Flocculant-dissolving system for Powdered Polymer Flocculants
The powdered polymer flocculants are one of the most widely used chemicals in the sludge dewatering processes.
Unfortunately, the polymers are not quickly dissolved in water due to their long polymer-chain length.
When the feeding rate of the chemicals to the water is too fast and/or in case of poor mixing, the powders may form masses (lumps), which results in a very slowed dissolution.
To attain a perfect dissolution of the powdered polymer flocculants, ARK offers a flocculant-dissolving system, FREETA-α.
This is an automated powdered flocculant feeding/dissolving system.
FREETA-α can continuously produce a polymer flocculant solution in a predetermined concentration.

🫙Anionic polymer flocculant (A1110 series)

The unit of PAM is expressed a formula of (-CH₂CHCONH₂-). The anionic PAM has an anionic group (-CH₂CHCOONa-) in the macromolecule to a certain extent. Depending on the anion fraction per polymer and the polymer chain length, the degree of flocculation is differentiated.
The anionic polymer flocculants are usually used for dewatering positively charged sludge. When inorganic coagulants having Al or Fe are dosed to the wastewater/slurry, small and compact flocs having a slightly positive charge are formed (because these metals are being positively charged). The anionic polymer flocculant bridges over the small flocs, yielding large flocs.

🧂Cationic polymer flocculant (C1492 series)

The cationic polymer flocculants are composed of acrylamide units and cationic units.Similar to the anionic PAM, the chain length of the polymers and the degree of cation fraction may be chosen depending on the nature of the slurries. Compared to the anionic polymer flocculants, the cationic ones can create robust flocs.
The cationic polymer flocculants are widely used for sludge dewatering, particularly in municipal wastewater treatment plants. This is because the sludge generated from the treatment plants is mostly organic solids, which are negatively charged. The cationic polymer flocculants bridge the negatively charged organic solids and build the flocs.
