The generic word ‘filtration’ can encompass many applications across a wide range of industries, the majority of which can be served by the commonly available filter media where process temperatures are low and / or the environment inert.
It therefore takes a very special medium to tackle the difficult and unusual conditions found in today's chemical, petrochemical or general process industries.
These difficult problems were solved by porous ceramic media that are chemically inert, stable and available in a variety of controlled and special grades, with temperature capabilities of up to 900ºC.
Available Ceramic Filter Media
We have a range of standard ceramic materials. Each has its unique characteristics and capabilities. The materials used most commonly are Pyrolith and Coralith.
Typical Filtration Tube Sizes
Various size,shape,pore size,porosity are available.
Flow Rates v Pressure Drop
Flow rate v pressure drop information can contact our sales rep.
Applications
Applications for filtration tubes fall into two main groups, each explained further on their own page:
- Gas and Air Filtration
- Liquid Filtration
Common Benefits
- Controlled pore size
- Controlled porosity and permeability
- Coalescing capability
- Chemically inert - can handle acidic gases
- High Temperature capability to 900ºC
- Range of standard element sizes
- Low cost of ownership
Filter Cleaning
The cleaning properties of an element are dependent on the contaminate and the conditions. Normal methods of cleaning are surface brushing, back flushing or cleaning with a suitable solvent solution. With depth filter media, cleaning only usually removes surface contaminate with particles trapped in the pores being difficult to remove. Once the pressure drop across the filter reaches an unacceptable level, and cleaning has failed to restore the flow, then the filters should be replaced.
