Flocculation is the process during which suspended matter in a liquid clumps together to form larger particles, called flocs. The flocs are then separated from the treated water. Using powdered activated carbon, the decanters remove suspended particles (including colloids), organic matter, micropollutants, and plant protection products. The water then passes through channels to the next treatment stage.

L'Ha每-les-Roses, March 4, 2025. Decanter room where PAC (Powdered Activated Carbon) injection and coagulation-flocculation take place. This is the first stage of water treatment. Flocculation is the process during which suspended matter in a liquid clumps together to form larger particles, called flocs. The flocs are then separated from the treated water. Using powdered activated carbon, the decanters remove suspended particles (including colloids), organic matter, micropollutants, and plant protection products. The water then passes through channels to the next treatment stage.

Tank filled with flocs and untreated water in the settling tank room where the PAC (Powdered Activated Carbon) injection and coagulation-flocculation take place. This is the first stage of water treatment. Flocculation is the process during which suspended matter in a liquid agglomerates to form larger particles, called flocs.
