Primescreen

Maximum efficiency in primary treatment

Primescreen®

Primescreen® is a completely self-cleaning conical disk filtration system which replaces traditional primary clarification in a fraction of the footprint and cost. Unlike other primary filtration systems, Primescreen® does not require compressed air, hot water or continuous back washing, vastly improving efficiency and making for a much simpler machine to maintain and operate. The installation of Primescreen®, thanks to its innovative technology, allows the plant to obtain immediate energy savings due to the reduction of Total Suspended Solids, BOD and COD, decreasing the load on the biological system, decreasing aeration requirements.

Dynamic Tangential Filtration

Dynamic Tangential Filtration®

The disks are kept in continuous rotation, and the flow crosses the filtration surface tangentially instead of orthogonally. This is the main feature of the Primescreen® technology.

The main feature and the uniqueness of Primescreen® has a specific name: Dynamic Tangential Filtration®.
Basically, the wastewater crosses the rotating filtration surface tangentially instead of orthogonally, as it does in the other filters. This guarantees a great advantage over other static filtration technology. The angle of incidence between the influent and the filtering media, combined with the continuous rotation of the disks, allows for a higher efficiency separation of the micro particles contained in the wastewater.

Primescreen® vs Others

Compared to traditional plain mesh filters, Primescreen® is characterized by an operational simplicity due to the total self-cleaning of the conical mesh in the filter, through the principle of adhesiveness.
