Filtration Devices

Back to Equipment case studies - 02/10/2019

A guide concerning the application, purpose and use of sediment pre-filters; complete with a funky orange table. Lovely.

What do sediment filters do?

Filtration devices or sediment pre-filters exist as a fine ‘sieve’ to clear water of particulates and dirt. If they are used in a larger system; they are called a pre-filter. They help protect larger systems from damage and allow them to work more efficiently by passing clearer water through them.

We stock a full range from 1-50 micron; A micron is calculated at approximately 1000th of a mm.

The lower the Filter’s Micron Size; the more effective the Filter is at dealing with particulates.

For example; a Spun filter at 5 Micron will be more effective at removing sediment and particulates than a 20 Micron filter. It will also block small sediment much lower on the filtration spectrum.


  • works by trapping sediment on the surface of the filter.
  • low pressure dro


  • Higher pressure drop

Spun (Melt-Blown)

  • Higher pressure drop

Carbon Block

  • Used to treat Chlorinated water
  • Most effective at a slow rate, allowing greater contact time
  • May need a high pressure to work effectively

GAC (Granular Activate Carbon)

  • Used to treat chlorinate water

Do I Need a Filtration Device?

A Filtration device should be used for any major water treatment system.

For domestic use, if your water contains sediment or particulates, a pre-filter should be used.

If your water tastes and smells chlorinated,  a carbon block or GAC should be used.

Any treatment process using a UV light should use a Pre-Filter to ensure optimal clarity when the light contacts the water
