Automatic Disc Filtration System

Helix Automatic 200 Series, 300 Series

Overview

The Azud Helix Automatic in-line self-cleaning equipment with disc filtering element is available with 2″ valves (200 Series) or 3″ valves (300 Series). Suitable for maximum flow of 256 cubic meters per hour.

The Helix system optimizes performance and energy savings and minimizes the frequency of backwashing, thereby saving water. A patented design and high-quality materials used in manufacturing guarantee maximum safety and extended life with high resistance. The modular configuration allows design options based on customer preferences or available space.

Automatic operation: 110 VAC, 220 VAC or 12 VDC.

Special options available for extreme pressures (low, high) and water conditions (sea or saline water, potable, acidic). Possible to perform backwashing with compressed air, minimizing water loss during backwashing.

Easy transport and installation. Pre-assembled equipment; fairly compact.

technology

The Helix Automatic Disc Filtration System backflushes one unit at a time while the rest of the units continue to filter.

Filtration stage: Water entering the filter enters through the Helix device, generating a centrifical effect that pushes particles in the water away from the stacked discs. Water passes through the grooves on the surface of the discs, leaving fine particles in and between the grooves.

Backflushing stage: Filtered water is introduced from the opposite direction through the filtering element structure, decompressing and spacing the stacked discs, which causes perfect cleaning of the discs’ grooves.

Solids expelled from the discs are evacuated through the drainage manifold. Filtration begins again with compression of the discs.

Backflushing is controlled by integrated drainage valve and a controller.
