Who is AZUD?

The AZUD disc filters are from leading Spanish manufacturer AZUD, who specialise in disc filtration equipment that perform advanced screening in a water filtration system. Born in some of the most arid regions in Europe, water and the environment is their passion. With the AZUD product operating in more than 100 countries around the world, it is a product tried and tested, globally.

The innovative AZUD disc filter

The innovative design of the AZUD filters allows them to be used in a broader range of applications from the industrial and commercial industries as well as for water treatment applications and irrigation.

These innovative designs have continually been improved through the R&D team as our ever-changing global climate changes. These innovative design features that give you the advantage are;

Helix – This patented design keeps the heavier solids in suspension away from the disk to allow more filtration and less backwash frequency. This also saves on water going to back wash.
Two Disc Types – The MG grooved disc channels the flow trapping smaller particles than the nominal degree. the WS wall disc increases efficiency to remove particles down to 5um where most other disc filters stop at 100um.
Filtration Surface Area – The taller disc stack and larger diameter pod allows for a minimum of 1620cm2 filtration area where the closest competitor only gives you 880cm2. Again, saves on water with less back washes.
Wider range of filtration degrees from 400um to 5um
Sequential self-cleaning with no interruption of your supply means there is no you have a non-stop filtration process.
Air Assist – With a more aggressive and effective backwash at high speeds, this system allows to again increase your water saving by a further 80% using ONLY 10 litres of water per pod per back wash.

The AZUD range are well-designed with highest quality of materials used in the construction to ensure a long lifespan and high corrosion resistance. The housings are constructed of polypropylene reinforced with fibre glass or polyamide reinforced with fibre glass. The discs are constructed with either polypropylene or polyethylene and the manifolds are constructed of high-density polyethylene.

These materials of construction allows you to use AZUD disc filters in high salinity water, chlorinated water and drinking water applications.

Key Benefits

The AZUD disc filter product line is a market leader in the above industries thanks to its meticulous design and technical excellence in manufacturing. It includes the following features:

Surface as well as depth filtration using the various disc technologies (MG and WS) ensures the highest quality water possible.
Self-cleaning with low pressure and very little water and energy consumption using the proprietary “DLP TECHNOLOGY”. During the cleaning stage, water production continues.
Low maintenance That doesn’t require any tools.
The ‘AZUD HELIX SYSTEM’, AZUD’s proprietary technology, delays clogging. This optimises filter performance and lowers the frequency as well as the intensity of maintenance.
The filters can operate in difficult conditions (water with high pollutant loads, saline environments, and seawater). You can always be sure of excellent water quality.

Design

In terms of design, AZUD has created several patents to improve the functionality of our AZUD disc filter equipment. These patents are primarily focused on self-cleaning, which is the most important stage in any filtration process.

The ‘AZUD HELIX SYTEM’ creates a centrifugal effect that removes larger particles from the filtration surface. This reduces the likelihood of clogging and decreases cleaning frequency. A second option is an air-assisted cleaning system. It reduces both the cleaning pressure and water flow, which increases the performance of the filter while also contributing to significant energy savings.

The AZUD HELIX Automatic product line allows clients to improve filtration results and reduce water and energy usage.

Water Resource Optimisation

Water scarcity is one of the biggest challenges in the water sector today. This is a crucial point to keep in mind as you plan, design, and implement any filtration requirement.

The second challenge is water quality. While water supplies are becoming increasingly polluted, consumers’ demands for quality water are growing.

Each drop of water must be returned to the natural environment. To make the most of it, we must also be conscious of the consequences of our actions.

These challenges force us to constantly improve our products. We not only develop better products or components that optimise performance, but we also develop solutions that make the most of this precious resource, water.
