Filtration, Purification & Clarification

Highly adsorptive clays that remove undesirable substances in industrial filtration & purifications processes

We provide a wide range of products under continuous development and renewal, designed to meet the needs in different refining and purification markets, including waste treatment and wastewater treatment.

Mineral resources available jointly to the expert knowledge in mineral processing make it possible to offer an extensive range of solutions to those industries whose processes include steps of purification or refining of a liquid product or where is required to treat waste or an effluent prior to the release to the Environment.



Kerosene & Jet fuel filtration

The specifications for transportation fuels have changed significantly over the last decades worldwide, with increasingly stringent legislation enforcing the production of high-quality clean fuels.

We offer a range of natural and calcined granular clay products specifically developed to adapt to the requirements of the Merox purification process. The purpose is for kerosene to go through a final purification stage. Our filtration products efficiently remove impurities by adsorption, obtaining high quality and clean fuel that will perform better while complying with the latest legislation requirements.

Thanks to the availability of our admixtures in various particle sizes and our selection of raw materials ―bentonite, sepiolite, and attapulgite grades ― our products remove effectively jet fuel and kerosene contaminants such as water traces, metals, surfactants, colour compounds and solid particles, among others.

Industrial Oils Filtration

Both fresh mineral oils and used ones need to be treated in order to remove solids and other impurities such as moisture, sulfur, metal traces, oxidation compounds and turbidity.

Filtration has a great significance in industrial production as it prolongs the life of the oils, maintaining equipment protected from premature failure, and thus, saving operating costs. In addition, bleaching clays have good adsorption properties. They can be used to purify the majority of new and used oils, making them the ideal option for industrial oils filtration and purification.

Thanks to their high porosity and surface area, our product range offers excellent adsorbent characteristics to clarify and purify petrochemical derivatives. They remove colour, odour and toxicity traits such as colloidal suspensions, organic products, organic acids, aromatic hydrocarbons and heterocycles, among other impurities.

Oil regeneration allows lube oils, lubricants, hydraulic oils, and other oil bases to be reintroduced to the market, thus cutting the carbon footprint and contributing to a more sustainable industry.

Gas Purification

Clays are widely used as adsorbents due to their selective adsorption, catalytic, filtration, and ion-exchanging properties.

Our portfolio offers specifically selected clay-based filtration products that provide substantial adsorptive capacity in relation to gases and water vapours. They efficiently remove the volatile organic compounds (VOCs), carbon monoxide (CO) and hydrocarbons (HC) produced by exhaust fumes. This cleaning process results in a more homogenised and stable final gas, preventing certain risks and accidents such as explosions.

Our products can be combined with other components, such as zeolites and activated carbon, to customise the adsorbent’s properties to the specific demands of each application and equipment

In addition, our products can adsorb the ethylene gas produced by fruits after harvest, thus enabling storage atmosphere control to prevent the ripening process.
