💧 ARK Flocculant-dissolving System, FREETA-α Overview
| Flocculant-dissolving tank volume | Up to 8 m³ |
| Working volume | Adjustable to either 33%, 67% or 100% of the total volume of flocculant-dissolving tanks |
| Types of solutes | Powdered polymer flocculant |
| System | A powder feeder and three flocculant-dissolving tanks in series |
💧Reasons that you need to install the flocculant-dissolving system at your factories/treatment plants
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 chain length. When the feeding rate of the chemicals to the water is too fast and/or in case of poor agitation, the powders may form masses (lumps), which results in a very slowed dissolution.
To attain a perfect dissolution of the powdered polymer flocculants in water, both a controlled agitation and a certain mixing time are essential. Since the polymers of the powder are present in a physically shrunk form, the macromolecules have to be expanded in water to maximize the flocculation effect. To allow the expansion, the polymer solution must be placed in the tank for 30-60 minutes, which is called maturation time.
The ARK’s Flocculant-dissolving System, FREETA-α, perfectly achieves the dissolution and maturation of the emulsion polymer flocculants in the dilution water.
💧Strong points of the ARK’s Flocculant-dissolving System, FREEAT-α
FREETA-α lineups are equipped with a set of agitators to not form masses (lumps) during the dissolution of the powdered polymer flocculants.
If the agitation is poor, the masses (lumps) are quickly formed, which are not dispersed in water. This results in overconsumption of the polymer flocculant in the sludge dewatering process.
The three tanks in series equipped with FREETA-α allow a perfect dissolution of the slowly soluble polymer flocculants.
🤝Customer-support services
You may utilize FREETA- α for conditioning any flocculant species in a desired concentration. Besides a powder form, both an emulsion form and a solution form may also be fed to the flocculant-dissolving tanks.
The powder feeder pushes the powdered polymer flocculant in the flocculant-dissolving tank at a predetermined feeding rate. In the flocculant-dissolving tanks in series, the powders are perfectly dissolved with the agitators. The product (polymer solution) does not have remaining masses (lumps) and is continuously produced from the system.
Yes. The hydraulic retention time over the three tanks in series has been designed to attain both perfect dissolution of polymer flocculants and their maturation.
Depending on the capacity of the existing flocculant-dissolving system, no expansion is necessary. Please inquire at ARK for further suggestions.

Vietnam has been dubbed the ‘new dragon of Asia" due to its spectacular economic growth. But beneath the glittering growth are serious growing pains. Endless waste, polluted nature, and graying skies. The Vietnamese government has recognized the seriousness of the problem and has drawn the sword of the law, but with great change comes great opportunity. Right now, Vietnam's environmental problems are paradoxically [...].October 28, 2025 -
Vietnam Water Market Insights Source: Water & Sewerage / Overseas Construction Association Hyo Eun Kim Vietnam's spectacular economic growth is no secret. However, there is another reality behind this spectacular growth that we need to pay attention to. That is the issue of water infrastructure. Despite having abundant water resources, dilapidated water facilities that cannot keep up with the pace of rapid urbanization and industrialization are a challenge that Vietnam must address, and at the same time, a barrier to new business [...]October 30, 2025
