There are 3 fundamental physical states:

• solid
• liquid
• gas

And a certain number of intermediary physical states such as paste.

Any pure body can be in any one of these states, depending on the physical and chemical properties of the ambient environment.

One of the important functions of industrial activity is that of separating the constituent phases of a mixture in order to eliminate or collect one or more of them.

Once the filtration processes have been previously selected and installed, the filter element may be studied, replaced or modified. The following essential parameters should be taken into consideration:

1 ) Fluid:

• Physical properties: temperature, viscosity, density, etc.
• Chemical properties: acid, base, salt

2) Dispersed phase:

• Nature
• Particle dimensions
• Concentration

3) Flow:

• Flow rate
• Loss of maximum allowable charge
• Desired filtration threshold
• Frequency and type of de-clogging

“Knowledge of these factors enables the material, the filter surface and the design of the filter element to be determined.”

• Max. differential pressure: 10 bars on request
• Temperature: max. 450°C.

Sintered Metal Cartridges

• Material: stainless steel 304L , 316L or special alloys
• Temperature: max 400°C
• Filtration thresholds: 1µm to 60µm

Applications: High temperature; catalyst recuperation; viscous fluids; polymer filtration;

The pads are formed from juxtaposed elements enabling them to be inserted via manholes. They may be square, rectangular, circular, ring-shaped or elliptical and are perfect for installations of all sizes. Each element of the pad can be delivered with support grids.

The choice is made depending on the following:

• Desired efficiency
• Allowable loss of charge
• Droplet size
• Viscosity and the entrainment rate of the liquid phase
• Gas flow rate variations
• Dust content
• etc.

Applications: Liquid and gas filtration - devesiculation; extraction; absorption; in refinery; petrochemistry; agroprocessing industry; fine chemistry, etc.

• Unlimited sizes and shapes.
• Low loss of charge
• High volumetric surface area relative to the specific weight
• Static operation

Made from spiral-rolled strips of metal canvas or embossed knits, the inserts are reserved for small installations. They are supplied on demand with support grids.

Applications: Distillation columns, absorbers, gas scrubbers, purifiers, extractor drums, depressurisation vases.

• Unlimited sizes and shapes.
• Low loss of charge
• High volumetric surface area relative to the specific weight
• Static operation

The metal mesh that forms the Eliminator Knit is not a rigid material and must be supported. We produce custom-made support grids from the following metals:

• Stainless steel AISI304L, 316L
• MONEL
• Soft galvanised steel, soft carbon steel
• Special alloys, etc.

Applications: Any device requiring the introduction of fluids and gases

• Distillation columns
• Absorption columns

The so-called “textile” filter element is manufactured according to specific selection criteria: the nature of the material of which it is made, the environment to which it must adapt, its behaviour on heating, its density, etc.

The environment could be:

• Solvent
• Acid
• Base
• Oxidant

The material:

• Polypropylene
• Polyester
• Polyamide
• Acrylic
• Cotton

Different qualities of material are used depending on the application, since the chemical, physical and mechanical properties of each material are different and appropriate to specific filtration criteria, as a result.

The construction of the filter element varies and a wide range is available.

A complete range of filter cartridges is available.

The categories of disposable cartridges depend on the following:

1. Type of Material: Polypropylene, nylon, polypropylene + fibreglass
2. Epoxy Impregnation: hydrophilic PVDF, hydrophobic PVDF
3. Retention threshold in µm from 0.3 µm to 200 µm
4. Support layers polypropylene or polyester
5. Core: polypropylene, stainless steel, nylon
6. Weld method: heat welded or not
7. Caps: polypropylene, polyester, nylon
8. Joints: Viton, EPDM
9. Dimensions: length X diameter

Applications: very highly viscous products, resins, inks, chemistry, petrochemistry, contaminant liquid, industrial water...

The canvases and sub canvases are supplied to measure for equipment such as: press filters, rotary filters, disc filters, belt filters, Kelly filters, spinner, and centrifuge, etc.

The dimensions must be defined in advance in your request, indicating the following:

1 - Width, length, distance and diameter of the hole; tray thickness; sleeve dimensions, etc. 2 - Type of material used 3 - The environment in which they are to be used.

Spheres of application: refinery; chemistry; water treatment; agroprocessing industry, etc.
