Disk Filter – AquaDisk

Aqua Aerobics – AquaDisk™ Cloth Media filter offers tertiary filtration  with low footprint where clarified effluent enters the filter and flows by gravity through the cloth media of the stationary hollow disks. The filtrate exits through the hollow shaft which supports the individual disks and flows to the effluent channel. As solids accumulate on the surface of the media, the water level surrounding the disks rises. Once a predetermined level is reached, the disks rotate and the media surface is automatically vacuum backwashed clean. Heavier solids settle to the bottom of the tank and are then pumped to a sludge tank or to the plant headworks. 

Why Cloth Media?

It’s not just “hydraulic loading” rate, but also “solids loading” rate that matters for an effective Tertiary Device (especially when filtering TSS and precipitated phosphorus solids).

  • Provides solids loading rate that is 7 to 12 times of a microscreen.
  • Extending filter fun time between backwashes with thousands of hair-like fibers to intercept and store solids particles.
  • Less frequent backwash to downstream processes (ie. UV).
    • During demanding conditions (plant upset or storm conditions) microscreen backwashing can result in a high frequency or continuous backwash providing an unplanned additional flow of 10% or more to the UV system. Ensure your downstream systems can accommodate excessive backwash from competitor microscreens.
  • Solids Removal (L/d) of technologies
    • Cloth Media= 700
    • Microscreen = 1
    • Deep Bed Filter = 700-1200
  • Surface Depth of Screen
    • Cloth = 3 to 5 mm
    • Microscreen = 0.06 mm
      • Cloth has 83x more depth

Features:

  • Capacity for each AquaDisk unit
    • Avg flow = 0.3 to 3.25 mgd each
    • Peak flow = upto 6.5 mgd each
    • 80% less footprint than sand filters with comparable capacity
  • MiniDisk available for low flows
  • Low energy consumption
  • Continuous Filtration even during backwash
  • Ideal for deep bed filter retrofits, new plants, expansion and microscreen replacements
  • Only 1 to 3% of flow is used for backwashing versus 8 to 10% for granular / sand filters.

Applications:

  • Tertiary filtration
  • Phosphorus removal
  • New and retrofit plants
  • Reuse / Recycle (California Title 22 approval)
