Process Components FLOCOPAC®.L
In a single closed system, FLOCOPAC®.L manages the following tasks:
Coagulation: The colloids contained in the water are normally have identical electrical charges and therefore repel each other. By adding a metal salt this electrical charge is removed; the colloids then agglomerate into micro flakes.
Precipitation: The treated water is decarbonised by adding milk of lime.
Flocculation: At this stage the actual flocculation reaction takes place through sludge circulation. Long-chain hydrocarbons act as a flocculant.
Sedimentation: The mixture of water and flocs is distributed evenly across the entire area of the sedimentation tank and, from here, pass to the settling zone located below the fine sedimentation zone. Most solids, in particular the larger particles, are separated from the liquid in this part of the system.
Fine sedimentation / Clarification: The roughly clarified water then passes into the fine sedimentation zone with its honeycombed modules fixed at a 60 degree angle, in which highly efficient removal of the remaining solids takes place.
