We are a BCORP-certified engineering company, specializing in offering sustainable solutions in the fields of seawater desalination, wastewater reuse and energy efficiency. From our headquarters in Madrid and Barcelona, we design, develop and manufacture compact and modular plants with high efficiency, aimed at meeting the specific needs of small and medium-scale companies in different sectors.
Our desalination and reuse division focuses on solutions that ensure the supply of drinking water and promote the reduction of the water footprint, in a global context of growing water scarcity and drought restrictions. We design desalination, water treatment and reuse plants capable of producing up to 2 million liters per day in spaces equivalent to two shipping containers, making them highly versatile, transportable and ideal for temporary or hard-to-reach facilities, such as seaports or other critical infrastructures.
These compact plants integrate state-of-the-art technology and stand out for their low energy consumption. In addition, they can be hybridized with photovoltaic installations, a solution developed in collaboration with our energy efficiency division, which offers turnkey solar projects for both companies and individuals, thus contributing to significantly reducing the carbon footprint of our systems.
We complement our offer with the distribution of advanced filtration solutions for large desalination and water treatment facilities, which allows us to cover a wide variety of operational needs in water treatment.
In its more than 10 years of experience, KEIKEN has experienced sustained growth, exceeding the industry average and consolidating an international presence with a portfolio of clients that includes IBEX 35 companies.
At KEIKEN we work every day with a clear purpose: to guarantee access to water and reduce the water and carbon footprint of each project. KEIKEN is innovation, commitment and efficiency at the service of water.
