Disc and screen filters

AZUD water filtration: self-cleaning filters with non-stop flow

AZUD HELIX automatic disc filters and AZUD LUXON screen filters remove sand, silt, algae and other particles from water. They clean themselves and keep supplying filtered water throughout the cleaning cycle.

Two technologies

Discs or screen?

AZUD makes both types of self-cleaning filter. The choice depends mainly on the type of particles in the water, the flow rate and the filtration degree required.

AZUD HELIX disc filter with disc cartridge

Disc filters

AZUD HELIX AUTOMATIC

A stack of grooved discs works as a depth filter, retaining particles on the surface and inside the stack. The patented AZUD HELIX device spins the water so that heavier particles are separated before they reach the discs – which means fewer backwashes.

  • AZUD 3D discs (MG or WS technology) for surface and depth filtration
  • Sequential backwash of each filter – filtered water supply never stops
  • AZUD DLP technology: efficient self-cleaning at low operating pressure
  • Corrosion-resistant polymers; tool-free maintenance

Best for: organic particles, algae and biofilm, water with fertilisers; finest filtration down to 5 µm (FT200 AA).

Screen filters

AZUD LUXON

An AISI 316L stainless steel screen retains particles on its inner side. When the differential pressure reaches the set point, the drain opens and suction nozzles travel along the screen in a helical path, sucking the dirt away.

  • Screens from 80 to 1,000 µm (LDB with stainless steel support from 10 µm)
  • Low-consumption AZUD suction nozzles
  • Carbon steel housing with epoxy-polyester coating
  • Control unit included

Best for: inorganic particles (sand, silt, rust) and high flow rates in a small footprint – up to 1,065 m³/h from one unit.

Equipment

AZUD equipment we supply

Seven series for flow rates from 21 to 1,065 m³/h per unit. All of them clean automatically without interrupting the water supply.

How it works

How the filters clean themselves

The controller monitors the differential pressure between inlet and outlet. When the filter clogs, it starts cleaning – and the water keeps flowing.

Cutaway of an AZUD HELIX disc filter during backwash

HELIX AUTOMATIC: sequential backwash

  1. Filtration: water flows through the disc stacks; particles stay on and between the discs.
  2. Trigger: when the differential pressure reaches the set point (typically 0.5 bar) or after a set time, the controller switches the 3-way valve of the first filter.
  3. Backwash: the discs are released and filtered water from the other filters flushes them in reverse into the drain.
  4. Next filter: the filters are backwashed one after another, so the station supplies filtered water all the time.

LUXON: helical suction nozzles

  1. Filtration: water enters the inside of the screen (on the MFE first through a 6 mm pre-filter) and flows outwards through it.
  2. Trigger: when the differential pressure reaches the set point, the drain valve opens and suction builds up in the nozzles.
  3. Cleaning: the nozzles move along the screen in a helical path and suck the retained particles into the drain.
  4. End of cycle: after the set time the control unit closes the valve. Filtration continues throughout.

FT200 AA: compressed-air-assisted backwash

With water carrying a lot of organic and sticky particles, compressed air at 4.5 to 6 bar helps clean the discs. Cleaning is more thorough and uses less water – from 10 l per filter. We can also supply the compressed air for the filtration station with a compressor from our range.

Applications

Where we filter water

AZUD self-cleaning filters protect equipment from particles and cut maintenance costs wherever water circulates or is reused.

Groundwater filtration

LUXON LDB removes sand and silt from wells and boreholes – up to 1,065 m³/h with one unit.

FAQ

Frequently asked questions

When should I choose a disc filter and when a screen filter?

AZUD HELIX disc filters are better for organic particles, algae and biofilm and for very fine filtration (down to 5 µm with the FT200 AA). AZUD LUXON screen filters suit inorganic particles such as sand and silt, and high flow rates in a small footprint – up to 1,065 m³/h from one unit.

Is the water supply interrupted during cleaning?

No. In HELIX AUTOMATIC stations the filters are backwashed one at a time while the others keep filtering. In LUXON filters the suction nozzles clean the screen while water continues to flow through the filter.

How much water does flushing use?

LUXON LCA uses 42 to 112 l per flush, MFE 112 to 280 l and LDB 16 to 180 l, depending on size. The AZUD HELIX device reduces how often disc filters need backwashing, and the air-assisted FT200 AA needs from 10 l per filter.

What pressure do the filters need?

HELIX AUTOMATIC operates from 0.8 to 10 bar and needs at least 1.5 bar to backwash. LUXON MFE and LDB need at least 2 bar at the outlet for cleaning, LCA 2.5 bar. LDB is also available as PN16. The FT200 AA also needs compressed air at 4.5 to 6 bar for backwashing.

Is a controller included?

LUXON filters come with a control unit (LCA battery or 220 V, MFE and LDB 220 V, 380 V available). HELIX AUTOMATIC stations do not include the AZUD FBC controller; we supply it separately – for 1 to 12 stations, powered by 220 V AC, 110 V AC or 12 V DC.

Can saline water be filtered?

Yes. The FT200 AA SW version is designed for water with 6,000 to 55,000 mg/l of dissolved solids (TDS); the standard version handles up to 6,000 mg/l. For LUXON LDB there are solutions for saline water and pressures above 10 bar.

What do you need for a quote?

Flow rate (m³/h), operating pressure, water source (well, river, cooling tower, process water), the desired filtration degree or the equipment to be protected and, if possible, a water analysis (particles, TDS, organic matter). From this we select the unit and prepare a quote.
