FT4DCL
Overview
The Azud Helix automatic FT4 self cleaning filtration system is composed of 3– 12 x 4” filter pods installed in-line performing in-depth filtration. The system includes 3” backwash valves operating on Azud’s DLP low pressure technology. When multi-filters are installed clean filtered water is used for backwashing the rest of the filters in the train ensuring the system continues to filter during backwash.
The patented Azud Helix anti-clogging deflector provides reliable filtration through centrifugal separation, reducing backwash frequency and reducing waste water.
Specifications
FILTRATION PHASE
- Water flows from the inlet manifold to the inside of the filter, passing through the anti-clogging deflector AZUD HELIX, which throws the heavy particles away from the disc stack, avoiding the quick clogging of the filter and minimising the backwash frequency.
- Water flows OUT-IN through the disc stack to the outlet manifold while particles bigger than the filtration degree are trapped in the discs
SELF-CLEANING PHASE
- When automatic backwash is activated, teh pressurised water flows IN-OUT, decompressing the disc stack.
- High-speed flushing water flowing through the spray nozzles, creates a tangentical cleaning effect that flush out the trapped particles.
