AQ MarTest provides professional on-site filtration services for off-spec fuels, oils and chemical products across global industrial operations. Filtration is performed directly at terminals, refineries, production plants and on-board vessels during loading or discharge, allowing contaminated cargo to be restored without unnecessary transport or disposal.
By treating the product at its original location, on-site filtration reduces operational downtime, avoids additional storage costs and minimizes product losses. This approach supports faster recovery while maintaining full compliance with operational and environmental standards.
Since its foundation, AQ MarTest has successfully treated more than 15 million metric tons of off-spec liquid bulk cargo worldwide. This operational experience makes the company a trusted partner for complex industrial filtration projects.
Transporting contaminated products to external treatment facilities creates additional risks, costs and delays. On-site filtration eliminates these issues by bringing certified mobile filtration equipment directly to the cargo.
In many cases, AQ MarTest performs in-tank recirculation, allowing the product to be reprocessed inside the existing storage tank. This significantly reduces handling risks and keeps product losses typically below 0.1%.
For terminals, cargo owners, insurers and underwriters, on-site filtration offers a faster and more cost-effective route back to specification.
Mechanical filtration removes visible and microscopic solid contamination from fuels, oils and chemicals. The systems can achieve ISO cleanliness levels below 15-12-9 and operate with flow rates up to 1000 m³/h.
Dedicated Jet-A1 filtration units approved according to EI standards are available for aviation fuel applications.
Chemical filtration removes dissolved contaminants using high-performance adsorbent media. This process is used for the treatment of chlorides, peroxides, carbonyls, dissolved iron, water and other dissolved impurities.
AQ MarTest absorber systems are fully PED Cat IV / CE certified and suitable for medium and large-scale chemical purification projects.
Magnetic filtration removes ultra-fine metallic contamination, while coalescing filtration separates emulsified water droplets from sensitive liquid products such as aviation fuels and specialty chemicals.
This combined approach allows treatment of a wide range of off-spec liquid bulk cargoes.
AQ MarTest routinely performs on-site filtration for products including:
Typical contaminants removed include:
The goal is always the same: restoring the product safely to specification for continued commercial use.
AQ MarTest improves and restores critical product specifications such as:
Laboratory validation supports every project to ensure treatment effectiveness before and after field execution.
All filtration projects are executed under ISO 9001, ISO 14001, ISO 45001 and VCA-P certified systems. This guarantees safe execution, environmental responsibility and full compliance with petrochemical industry standards.
AQ MarTest combines laboratory expertise, field execution and certified mobile equipment into one complete on-site filtration service.
When product quality is compromised, on-site filtration provides the fastest path back to operational continuity.

On-site filtration is the purification of contaminated or off-spec fuels, oils or chemicals directly at the terminal, production site or vessel where the product is stored. This avoids transport and reduces operational downtime.
