An appropriate pretreatment process is the most effective solution to pollution caused by particulate matter, colloids, and suspended substances that block the flow channel of membrane elements. As such, adding a flocculant becomes essential to the pretreatment process. Our GPF series flocculant is a high-efficiency pretreatment synergist capable of destabilizing, coalescing, and settling organic colloids, inorganic particles, and organic solvents through substantial electrical neutralization and bridging. It also has certain decolorization, sterilization, and algae removal effects. This flocculant is typically added before the multi-media filter to help enhance the removal of organic colloids, inorganic particles, organic solvents, etc. It significantly reduces the phenomenon of pollutant fouling on the membrane surface.

Operating Instructions

Before use, the standard solution should be formulated into a 4% concentration (4kg standard solution + 96kg water). If minor sedimentation is observed, shake well; it will not impact the product’s performance. The typical dosage is between 0.5 and 10 ppm of the standard solution. When water quality is good (tap water, clean surface water, etc.), the dosage should be 0.5 to 2 ppm. Too low and too high a dosage can be unfavorable for the flocculation process, so minimizing the dosage while maintaining the flocculation effect is essential. The precise dosage should be determined after a small-scale trial. Consultation with an EcoLan technical engineer is also available, who can recommend an appropriate dosage based on water quality and process characteristics.

The dosage point should be located far from the filter inlet, and the injection point should ideally be in the center of the water flow pipe. This setup ensures a uniform mix of the solution during periods of turbulent water flow.

Benefits of Flocculating Agent

Flocculating agents, also known as flocculants, promote the clumping together, or flocculation, of fine particles suspended in liquids, which is a key step in various water treatment processes. The benefits of using flocculating agents include:

  1. Enhanced Water Clarity: By aggregating fine particles into larger flocs, flocculants improve the clarity of water, which is essential for water treatment facilities to produce clean and safe drinking water.
  2. Improved Water Treatment Efficiency: Flocculants increase the size of particulates, making them easier to remove through filtration or sedimentation. This can lead to more efficient water treatment processes, as larger flocs are easier to separate from the water.
  3. Reduction of Turbidity: The primary purpose of flocculation in water treatment is to reduce turbidity, which is the cloudiness caused by suspended particles. Clearwater is aesthetically pleasing, safer for consumption, and less damaging to aquatic ecosystems.
  4. Cost-Effectiveness: Flocculants can be cost-effective as they reduce the need for more expensive treatment methods. They can also lower the overall sludge volume that needs to be treated and removed, leading to savings in sludge handling and disposal costs.
  5. Versatility: Flocculants are used in various industries and applications, including drinking water purification, wastewater treatment, mining, and the food and beverage industry. They can be tailored to specific needs based on the type of suspended particles, pH level, and other factors.

Applications of Flocculating Agent

Water Treatment

One of the primary applications of flocculating agents is in water treatment processes. They remove solids from water in wastewater, stormwater, and drinking water purification. In wastewater treatment, flocculants help to remove suspended solids, organic matter, and phosphorus, which can lead to algae growth if released into natural water bodies. The process involves adding coagulants and flocculants to the water, which neutralizes the charge of the particles and allows them to aggregate into larger flocs. These flocs can then be removed by settling or filtration.

Mining Industry

In the mining industry, flocculants are used in the sedimentation, filtration, or centrifugation of mineral processing slurries. They help separate solids from liquids, which is a critical step in the extraction of minerals. The NASFLOC range, for example, includes various flocculants designed for different mining applications, ensuring maximum performance and cost efficiency.


Flocculating agents are also used in the papermaking industry to improve the retention of fiber fines and fillers during the papermaking process. They help in conditioning pulp and paper sludge, an important step in recycling and treating paper industry waste.

Environmental and Health Considerations

While synthetic flocculants, such as polyacrylamides, are effective, there is growing interest in biodegradable and environmentally friendly alternatives. This is due to concerns about the non-biodegradability of synthetic flocculants and the potential release of toxic monomers into water sources. Research is ongoing to develop “green” alternatives based on biopolymers like starch or cellulose.

Industrial Applications

Flocculants are also used in various industrial applications where separating solids from liquids is necessary. This includes effluent treatment from industries that produce significant quantities of phosphorus or other contaminants that require pre-treatment before being released into wastewater treatment plants.
