100% Stainless steel
The machine is entirely built in stainless steel, to ensure efficiency over the years of operation.
Maximum efficiency in primary treatment
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.
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.
The machine is entirely built in stainless steel, to ensure efficiency over the years of operation.
Utilizing vertical filtration disks significantly reduces the overall footprint, saving valuable space compared to other technologies.
The inclination to the water flow crossing surface guarantees the excellence of the filtration.
All the internal mechanisms are designed to guarantee extraordinary performance.
The machine has an intuitive, simple, and totally autonomous working principle.
AISI 316 L stainless steel filtering mesh.
Polyurethane filtering mesh.
Almost unlimited duration.
AISI 304 stainless steel conical disk wheels.
Plastic material rollers supporting the filtering mesh.
Almost unlimited duration.
The totally self-cleaning system that exploits the principle of adhesiveness.
No air or water is required for continuous backwashing, but occasional washing of the filter media can be carried out using
plant service water at a pressure of 4 Bar.
Continuous washing system carried out by means of a compressed air collector in plastic material and hot water to wash the mesh at a pressure of 8 Bar.
Lower energy consumption costs and lower operating and maintenance costs due to lower complexity.
Installed for the rotation of the filtering disks, with ON-OFF operating system.
Continuous operation.
N. 2 electric motors installed on the machine with continuous operation and in addition further external engines.
Lower energy consumption costs and lower management and maintenance costs due to lower complexity.
Nearly silent in operation.
High noise due to the compressed air jet.
Absence of noise.
Low odor emission.
No need for an aspiration system.
Odor emission produced by the compressed air jet with consequent need to install an aspiration system.
No odors and consequently no energy consumption or maintenance required for operating and aspiration system.
Very low energy consumption, with the elimination of much more energy intensive washing system which other manufactures must utilize.
High energy consumption due to the presence of the motor for moving the mesh, the driving motor of the expulsion screw, the motor
of the air compressor, the engine of the odor aspiration system.
Consumption of methane gas (or electricity) for the production of hot water for the filtering media washing system.
Dramatically lower energy consumption.
Presence of an overflow emergency gravity system inside the machine.
Overflow emergency system is managed by an actuated valve feeding the filter, which can fail or not operate during a power outage.
Greater installation flexibility.
Eliminates the worry of an overflow due to the failure of an actuated valve or during a power outage.
