Twin Filter - Offshore Filtration Equipment and Consumables

Twin Filter designs and manufactures a wide range of filtration equipment and consumables for the offshore industry. The company is renowned as a problem solver and supplies filter services and solutions for completion / gravel pack fluids, work over fluids, water injection (water flood), wastewater treatment, pipeline flushing, produced water treatment and sea water intake filtration, pre filtration RO.


The vertical pressure leaf filter unit or our filter press in combination with the Duplex cartridge filter unit have proved to be the most effective and HSE friendly method for filtration of brines. For nearly two decades, Twin Filter has been designing, manufacturing and supplying complete filter packages, including equipment and consumables to all major oilfield service companies.

Our packages includes:

  • DE filter unit - vertical pressure leaf (semi-automatic self-cleaning)
  • DE filter unit - filter press
  • Duplex cartridge filter unit
  • Bag filter unit
  • Filter consumables (filter cartridges and DE material)
  • Polymer shearing device
  • Pump unit (diesel driven)
  • High Pressure Filter units (well head)
  • Membrane Cross Flow systems for produced water separation
  • Coalescer systems for produced water treatment
  • Voraxial Separator for separation of oil / water /solids
  • Powder Handling System for safe, dust free and automatic dosing of DE media in slurry skid


We also manufacture filter cartridges especially for the oilfield industry. Our filter cartridges guarantee the clean fluids necessary for maximum reservoir protection and environmental yield during operations. Our range of filter consumables covers fully welded absolute and nominal rated filter cartridge, high-flow cartridges, stainless steel filter elements, filter bags, oil adsorption cartridges / media and diatomaceous earth.


After a high pressure pump debris and solids can occur in the injection water at the well head, these solids will plug off the reservoir. Therefore the water, before if will be pumped down hole, needs to be filtered down to the required filtration degree. Twin Filter design and built high pressure filter units for flows up to 250m3/hr and 6,500psi down to 0.5micron. These unit can be complete skid mounted with manifold and quick opening closure for quick and safe opening of the filter vessels.


Twin Filter builds complete systems that are specially designed for the high demands of the offshore industry. Twin Filter filter units are automatically self cleaning, which guarantees a continuous flow without interruption and a 100% cleaning of the filter element.

Clean seawater is used in various oilfield applications, i.e. water injection, water flood, pipeline flushing, cooling water intake, process water, ballast water and pre-filtration.

Twin Filter's automatic self cleaning filter units are capable of flow rates up to 4,000m3/h per unit and a working pressure of up to 100bar. Our units are Explosion proof operated and are made from different types of (stainless) steel.


All fields produce water and condensate with the oil and gas during production. Produced water often contains a high level of dissolved and free hydrocarbons after the first separation and before it is discharged overboard or re-injected into the reservoir.

Twin Filter designs, engineers and builds complete systems that can achieve discharge levels <1ppm by several technologies such as; Voraxial Separator for bulk separation of oil, water and solids, coalescer systems for polishing PW, ceramic membranes for automatic separation of produced water (emulsified oil), absorption / adsorption cartridges (Oilclog and Oilblock) and media for easy and effective polishing waste and produced water. Our (combined) technologies are able to meet the most stringent discharge requirements on and offshore.


A full range of equipment is available for rent, including VPL unit, filter press, cartridge filter units, single vessels, automatic self cleaning strainers.
