Advantages

The industrial filter offers a separate storage space for separated solids, which means that they do not directly affect the filter element.

Thanks to the sophisticated design, the inclined filter element can be removed quickly and easily. This enables time-saving maintenance and reduces machine downtime.

Thanks to the sophisticated design, the inclined filter element can be removed quickly and easily. This enables time-saving maintenance and reduces machine downtime.

 

The filter is extremely low-wear as it contains no moving parts. This not only minimizes maintenance requirements, but also reduces operating costs by extending the service life of the components.

Individual solutions

Customized special solutions for solid-liquid separation are developed for specific customer requirements. These can relate to special materials, individual sizes or application-specific adaptations. This ensures that the water filter can be perfectly integrated into the existing system and provides the best possible filtration performance for your industrial application.

Flexible cleaning

The filter can be cleaned either manually or fully automatically, depending on requirements. Manual cleaning offers a more cost-effective option for less demanding applications. Automatic backwashing is controlled by a control system and ensures continuous filtration processes. This allows for on-demand adaptation to different operating requirements in the industry.

Comprehensive protection for sensitive systems

Our filter systems reliably protect industrial components such as plate heat exchangers, spray nozzles, pipe systems, pumps and microfiltration systems. They contribute to environmental protection by protecting end products and water resources from contamination. Thanks to their high filtration performance, they are suitable for cooling water, river water, sea water, ballast water, process water, oils, emulsions and water infested with mussels. Drinking and waste water can also be cleaned effectively. This ensures sustainable use and reliable solid-liquid separation.

WHY A BACKWASH FUNCTION?

A backwash function ensures continuous cleaning of the filter element and prevents clogging. The differential pressure measurement detects the degree of soiling and activates the backwashing process as required. This keeps the filtration permanently efficient without the need for manual intervention.

HOW DOES THE BACKWASH FUNCTION?

Sobald der definierte Differenzdruck erreicht ist, öffnet sich die motorbetriebene Rückspülarmatur. Die hohe Strömungsgeschwindigkeit spült Schmutzpartikel aus dem Filter. Nach dem Bernoullischen Gesetz entsteht ein Unterdruck, der Reinwasser entgegengesetzt der Filtrationsrichtung durch das Filterelement leitet und angesammelte Partikel entfernt. Nach 15–20 Sekunden endet der Prozess automatisch, ohne die Grobfiltration zu unterbrechen.

The filtration process of the plate filter



The raw water enters the filter via the inlet flange and flows through the filter element.

Dirt particles are reliably filtered out, while purified water emerges on the clean water side. Coarser particles settle in the dirt collection area.

A differential pressure measurement continuously monitors the degree of contamination of the filter element. When a defined limit value is reached, backwashing is activated automatically.

The motorized backwash valve opens, generating a high flow velocity. Clogged dirt particles are loosened and flushed out via the flushing water outlet.

According to Bernoulli's law, a vacuum is created in front of the filter element, causing pure water to flow in the opposite direction to the filtration direction and effectively removing any remaining particles.

The backwash valve closes automatically after 15-20 seconds. Filtration remains active throughout the entire process, ensuring continuous operation.

The Filter element

The filter element is made from a reinforced slotted screen design, which means it can withstand even high differential pressures. Thanks to the integrated handle, it can be quickly and easily removed from the filter housing during inspections. Depending on requirements, the filter element can be made of different grades of stainless steel to ensure optimum resistance and filtration performance.

Electrical control

The backwashing process is initiated automatically - either time-controlled or depending on the differential pressure. This enables fully automatic filter operation. The standard control unit communicates with the customer's process control system (PCS) and provides the following signals: 

  • Collective fault 
  • Ready for operation 
  • Filter flushing 
  • External triggering of filter backwash 
  • External release of the filter backwash
[Translate to English:] elektrische steuerung des JET Filters

Differential pressure measurement

Differential pressure measurement The differential pressure measurement ensures precise monitoring of the filter performance. It includes: 

  • Visual display of the operating pressure upstream of the filter 
  • Visual display of the differential pressure 
  • Two freely adjustable switching contacts 
  • Automatic start of filter rinsing 
  • Alarm signal for critical pressure conditions
[Translate to English:] Differenzsdruckmessungsgerät

Venturi nozzle with backwash valve

The venturi nozzle is specially adapted to the customer's operating conditions in order to ensure an optimum amount of flushing water and avoid pressure fluctuations in the pipe network. The backwash device is equipped with an electric or pneumatic actuator as standard, ensuring precise and reliable control of the backwash process.
