Automatic filters

Three filtration techniques explained:
– Centrifugal separation:
The water is led into the filter via the spiral ring. A ring with angled blades/vanes. This causes the water to rotate when entering the filter. The resulting centrifugal forces push dirt particles to the wall of the housing keeping the filter disc clean for longer periods.

– Surface filtration:
The water will then pass through the pores of the disc package (disc stack). Particles larger than the pores will remain behind on the filter surface, which is the surface filtration similar to that of a screen filter.

– Depth filtration:
Finally, the smallest particles along with the water flow between the discs of the disc package. The stacked grooved discs create a depth matrix. The remaining particles are trapped in this depth matrix and only the clean water leaves the filter.

Three cleaning mechanisms explained:

– Opening the filter matrix. The grooved filter discs are separated from each other.
During cleaning a 3-way valve allows water from the clean side (outlet) of the filter to flow in reverse direction into the filter. The water is pressed against the spring pressure of the disc package. The disc holder extends and the grooved filter discs de-compress and open up. Embedded dirt can wash away without obstruction.

– Dirt removal with tangential spray jets.
The Multi-jet nozzle system on the inside of the disc package spray the dirt of the opened discs with powerful jets.

– Unloading dirt by vibration and spinning of the filter discs.
The water from the jet nozzles contacts the discs and the grooves of the disc at an angle. This will result in spinning and vibrating, creating extra energy to remove the dirt.

Cleaning efficiency and reduction of back wash water.
To reduce the water consumption for cleaning and also to further increase the cleaning efficiency, compressed air can be used in the AA (Air Assisted) version of the disc filter.

The AA version is equipped with an additional empty filter housing on the clean water side of the filter system. During filtration the housing will fill with clean filtered water and serves as a back wash water reservoir. The reservoir has a compressed air connection which adds pressure during the cleaning cycle. At the time of cleaning the three way valve switches the flow of one of the filter modules and reverses the direction of flow in this filter. Compressed air pushes the water from the reservoir through the filter module on back wash. The clean water flows in the opposite direction through the filter into the back wash water outlet. The compressed air expands and gives the back wash water a high speed, cleaning turbulence and impact energy.

Result:
– Minimum water usage: (15 liters).
– Efficient cleaning without water pressure.
– Expanding air provides high speed rinsing, cleaning turbulence and high impact energy.
