Cartridge Filtration Unit
Mainly used for polishing new brines and filtering seawater and fresh water. By using absolute rated
filter elements a guaranteed cut in the ‘size’ of the contaminating particle is achieved. The maximum
flow rate through each of these units is 18 barrels/minute and for this reason, they are usually
considered as the first option when planning completion fluid filtration. The cartridge unit is easy to
operate and only requires one operator per shift. Fluids that are heavily contaminated with soft
compressible solids like barite and clay (which have a low permeability when compacted) tend to
block the elements very quickly resulting in numerous and costly change-outs. They are also
installed downstream of a diatomaceous earth filtration system and fitted with 2 micron absolute filter
elements in order to provide a final polish. These robust units are widely used in the oilfield industry
and require little maintenance.
• Variety of cartridge types and ratings available.
• Can filter brine, acid, diesel, gels.
• Best suited to relatively clean fluids like seawater or pre-filtered brine.
