Filtration Services

AQ MarTest – Certified. Safe. Responsible. Reliable.

AQ MarTest offers on-site filtration and purification services for off-spec fuels, oils and chemical products around the world. Our operations are performed directly at storage terminals, production sites, or on-board vessels during loading or discharge, using certified state-of-the-art filtration equipment and internationally approved procedures.

As an innovative leader in mobile filtration, AQ MarTest helps clients resolve contaminated liquid bulk cargo issues quickly, safely and cost-effectively. Since its foundation, the company has successfully treated over 15 million metric tons of off-spec material for major producers, traders, terminals, insurers and cargo underwriters worldwide.

Laboratory Support

In our laboratories in Rotterdam and Houston, we can assess — free of charge — whether a contaminated product can be recovered by filtration. Our experts can perform filtration trials and in-house analyses to determine the most efficient treatment method before actual field deployment. This ensures each mobile filtration operation is based on data-driven efficiency and verified performance.

AQ MarTest filtration equipment

AQ MarTest operates a powerful fleet of fully mobile filtration systems, engineered for rapid global deployment and built to solve off-spec challenges on-site. With certified technology, modular designs and high-performance capacity, we restore off-spec cargo safely and efficiently without transport delays, downtime or emissions.

Particle Filter Units

Our Particle Filter Units form the core of our rental and service fleet. Offering flow rates up to to 1000 m³/h and filtration down to 0.5 microns. Our fleet includes high-pressure gas filtration units up to 60 bar, fully PED/CE certified stainless steel particle filter units and EI-1596 Jet-A1 approved units for aviation fuels. Our filter systems deliver precise particle filtration for bulk liquid cargos.

Application: On-site particulate removal for fuels, petrochemicals, and chemical bulk liquid cargos at storage terminals, production plants and on board of vessels

Small Absorber Units

Developed and Manufactured by AQ-MarTest. Our units are fully PED Cat IV/CE certified, engineered and constructed in accordance with EN 13445 standards, ensuring maximum safety and reliability.

The system allows safe replacement of used absorbent materials while reducing vapour emissions to zero. Built entirely from stainless steel (1.4404), each unit is pressure-tested to 23.11 bar, rated for a working pressure of 15 bar and suitable for operating temperatures from –20°C to +100°C.

Thanks to their compact and practical dimensions, the units can be deployed quickly on site and are easily transported by truck or air freight.

Application: Chemical polishing and reconditioning of medium to small cargoes on-site at terminals and production plants.

Large Absorber Units

In terms of specifications and operation, these units are identical to our smaller adsorber units. However, with a total capacity of 8,250 litres, they are ideal for processing larger volumes or handling heavily contaminated products.

The system enables safe replacement of saturated absorbent materials while reducing vapour emissions to zero.

Built within a 20ft container footprint, these high-capacity units offer both efficiency and practicality. They can be rapidly deployed on site and are suitable for transport by truck, sea freight or where applicable air cargo.

Application: Large-volume chemical filtration and reconditioning of tanks, terminal inventories, and bulk cargoes.

MODULAR, EMISSION-FREE AND BUILT FOR GLOBAL DEPLOYMENT

All AQ MarTest filtration equipment features modular designs for rapid mobilization by truck or air freight, ensuring fast response wherever filtration is required, onshore or offshore. Our in-house manufactured units guarantee complete containment limiting vapor emissions during media replacement, ensuring maximum safety and environmental protection.

Thanks to this flexibility, AQ MarTest operates seamlessly in ports, storage terminals, industrial plants and offshore environments, delivering reliable mobile filtration services anytime, anywhere.  With our certified, mobile and highly adaptable filtration fleet, AQ MarTest provides safe, cost-effective on-site treatment, restoring off-spec cargo to specification while eliminating unnecessary transport, emissions and operational downtime.

Filtration techniques explained

AQ MarTest delivers high-performance on-site filtration using a complete suite of mechanical, chemical, magnetic and coalescing technologies. Each technique plays a vital role in restoring product quality, removing contaminants and recovering degraded or off-spec liquids safely and efficiently. Together, they enable us to treat nearly all liquid bulk cargoes from fuels and petrochemicals to complex industrial chemicals.

Mechanical filtration

Using our mechanical filtration units we are able to remove both visible and microscopic particulates that compromise product quality. With multiple units connected in series, our systems achieve ISO cleanliness levels of < 15-12-9, ensuring exceptionally clean product streams.

For aviation fuels, we deploy our dedicated EI-1569 Jet-A1 particle and coalescer filter units, enabling compliant, high-integrity on-site filtration directly at terminals or storage locations.

Chemical filtration

Chemical filtration uses high-performance adsorbent media to purify liquids by removing dissolved contaminants. This technique allows us to remove molecules, resulting in water content levels < 5 ppm, chloride content  < 0.5 ppm, peroxide/carbonyl content to < 1 ppm, color spec of < 5 Pt-Co and many more.

This method is ideal for restoring chemical stability, improving appearance and meeting stringent product specifications.

Magnetic filtration

Our magnetic filtration systems remove ultra-fine metallic contaminants using powerful magnets. Using the patented PREMAG MHD / MAGFIL-300 ATEX technology, we remove sub-micron metal particles at flow rates up to 350 m³/h.

Each system features an ATEX-certified self-cleaning mechanism, ensuring safe, continuous operation in hazardous environments.

Coalescing filtration

Coalescing filtration targets or water droplets that remain emulsified in the product. By merging these micro-droplets into larger, separable drops, this process enables efficient removal and ensures clean, stable product quality, particularly important for oil and moisture-sensitive aviation fuels.

Areas of Application

AQ MarTest provides high-performance on-site filtration and off-spec treatment for a wide range of liquid bulk cargoes, industrial streams and petroleum products. Our advanced mechanical, chemical, magnetic and coalescing filtration technologies allow us to remove contaminants, restore product quality, and return liquid cargo to specification safely, efficiently and without the need for transport.

On-Site Filtration of Contaminated Liquid Bulk Cargo

AQ MarTest provides on-site filtration directly where the cargo is stored on land or at sea, using fully mobile and certified filtration equipment.

This approach eliminates transport costs, avoids additional storage requirements and minimizes operational downtime.

In many cases, we perform in-tank recirculation, enabling reprocessing inside the cargo tank with product losses typically below 0.1%. This makes on-site filtration one of the most cost-effective and environmentally responsible solutions available.

Oil Filtration Services


For petroleum and lubricant cargoes, AQ MarTest provides specialized oil filtration services designed to remove particulates, water and other contaminants. Our advanced filtration processes can restore color, odor, appearance, ISO cleanliness, FBT and other specs, while ensuring the quality and integrity of the product remain fully preserved.

The result is a cleaner, more stable and more reliable product that meets required specifications

On-site Filtration / Off-Spec Treatment

At terminals, refineries, chemical plants and production sites, AQ MarTest handles process streams or stored liquids that require purification or off-spec correction prior to blending, transfer or sale.

Our industrial filtration solutions are designed to be fast, safe, compliant and fully adaptable to both continuous operations and urgent interventions.

Using these advanced techniques and application-specific services, AQ MarTest delivers reliable, cost-effective on-site filtration and off-spec treatment restoring product quality safely, efficiently and without transport or downtime.
