Water and Desalination

In a world facing increasing challenges regarding water access, KEIKEN Engineering stands as a benchmark in technologically advanced and compact solutions for desalination and water treatment, covering all human needs, whether domestic, industrial, or for irrigation...

Furthermore, we offer support and key supplies to international companies in the water sector to ensure the success of their projects.

Filter Media / Anthracite

Anthracite is a very hard mineral coal characterized by its high carbon content, which can reach up to 95%.

Filter Media / Zeolite

Zeolite is a high efficiency filter media, which reduces the OPEX of a traditional filtration system by up to 50%.

Filter Media / Pumice stone

Our pumice stone complies with the UNE-EN 12906:2013 standard for the treatment of water for human consumption. Its low specific gravity, high porosity, and excellent filtration properties make pumice a good alternative to anthracite for SWRO and desalination applications.

Filter Media / Activated Carbon

Activated carbon is an absorbent with high carbon content and high internal porosity.

Filter Media / Garnet

Its chemical properties, hardness and durability make Garnet an ideal filter media.

Filter Media / Manganese Dioxide

AquaMandix is mainly constituted by Manganese Dioxide and is characterized by a high catalytic activity.

Filter Media / Sand

Sand is one of the most commonly used materials as a filter media for water filtration.

Filter Media / Gravel

Gravel is used as a filter media support, because it is an economical material and does not give any characteristic to the water.

Filter Media / Limestone

Our calcite with a calcium carbonate content higher than 98% is a specific product for water remineralization.

Desalination plant

We offer solutions for the treatment of seawater, brackish water, and/or water requiring purification through compact containerized plants. With Plug & Play technology and automated systems.

Treatment plant

We find the best treatment solution for wastewater with different parameters and flow rates. The goal is to give a new use to the treated water, supporting our clients in reducing their water footprint in commitment to the environment and sustainability.
