Improve Component Cleaning Efficiency

FLOCOPAC® is a flocculation and precipitation reactor combining several functions that can be used for various clarifying tasks, for example in the food and beverage industry, pulp and paper production, power generation, and oil and gas industry. It is based on the principle of optimized flocculation and precipitation through contact sludge recirculation and characterized by almost ideal flocculation and a multi-zone clarification, in which specially designed honeycomb modules perform the last step of fine clarification.

In a single closed system, FLOCOPAC®.L manages the following tasks:

Coagulation: The colloids contained in the water normally have identical electrical charges and therefore repel each other. By adding a metal salt (flocculent) this electrical charge is compensated, the colloids then agglomerate into micro flakes.

Precipitation: The treated water is decarbonized by adding milk lime.

Flocculation: At this stage, the actual flocculation reaction takes place through sludge circulation. Long-chain hydrocarbons (Polyelectrolytes) act as a flocculants.

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.
