• ADDITIONAL INFORMATION
FILTRATION PHASE
Raw water enters from the inlet manifold to the coarse screen, trapping larger particles that could interfere with the filter cleaning mechanism - in vertical models, large and heavy particles are separated by gravity.
Then water flows IN-OUT through the weave wire screen, trapping in the inner screen surface bigger particles than the filtration degree. Clean water flows out through the outlet manifold. Particles build-up creates a filter cake that increases the pressure differential between inlet and outlet, and this activates the cleaning cycle when the pre-set point is reached.
• SELF-CLEANING PHASE
Clean water supply is not interrupted when the cleaning cycle is activated. The cleaning phase starts with the opening of the drain valve, that creates a pressure gradient between the pressurized inner filter and the atmosphere. At the same time, the suction nozzle scanner spirals along the complete inner surface of the screen.
As a result of the pressure difference, a high velocity Suction Effect is created at the inlet of the nozzles, making the water flows OUT-IN through the filter element and vacuuming all the particles retained on the screen surface.

• ADDITIONAL INFORMATION
AZUD HELIX AUTOMATIC backflushes in only one station while the rest of the equipment is in filtration stage, supplying the installation.
- Filtration stage: The helix generates a centrifuge helical effect, which moves away from the discs the particles in the water. Through the discs is made the in-depth filtration process.
- Backflushing stage: The filtered water is introduced in the opposite direction through the filtering element structures, decompressing the stacks of discs and making the backflushing.
The solids expelled from the discs are evacuated by the drainage manifold.
The filtration stage starts again with the compression of the discs.
