KEIKEN ENGINEERING SL
About
KEIKEN Engineering is a Spanish firm with offices in Alcobendas (Madrid) and Barberà del Vallès (Barcelona), holding ISO 9001:2015 certification through Bureau Veritas and B Corp certification. The company's water division engineers and manufactures compact containerized desalination plants in plug-and-play configurations for seawater, brackish water, and potabilization, employing reverse osmosis, multi-effect distillation, multi-stage flash, forward osmosis, adsorption desalination, membrane distillation, and ultrafiltration. Their filtration media portfolio includes anthracite (up to 95% carbon), zeolite (claiming up to 50% OPEX reduction versus conventional media), pumice (UNE-EN 12906:2013 certified for drinking water), activated carbon, garnet, AquaMandix manganese dioxide, sand, gravel, and calcite (over 98% calcium carbonate for remineralization). KEIKEN also supplies multimedia filter tanks, cartridge filters, MBBR carriers, intake strainers (crepinas), polyelectrolyte preparation units, chemical dosing skids, and blowers. Wastewater reuse plants target industrial water footprint reduction. Their energy division provides photovoltaic installations, LED lighting, electrical consumption optimization, and home automation. A member of the Catalan Water Partnership, KEIKEN delivers engineering consultancy, feasibility studies, turnkey project execution, and technical due diligence.
Key Products
Plug-and-play automated desalination systems housed in shipping containers for seawater, brackish water, and potabilization applications.
Membrane-based desalination systems that remove salts and contaminants from seawater and brackish water using high-pressure membrane filtration.
Thermal desalination technology that uses multiple evaporation stages to produce fresh water from seawater with low energy consumption.
Thermal desalination process that flashes heated seawater through multiple pressure stages to produce distilled water.
Osmotic-driven membrane separation technology using a draw solution to extract water from saline sources.
Thermal membrane separation process combining membrane technology with thermal distillation for high-purity water production.
Membrane filtration systems that remove suspended solids, bacteria, and viruses from water using ultrafiltration membranes.
Ion exchange systems that remove dissolved minerals and ions from water to produce high-purity demineralized water.
Treatment plants that purify industrial and municipal wastewater for reuse, reducing water consumption and discharge.
Granular filter media for multimedia filtration systems in water treatment, each offering specific removal capabilities for suspended solids, manganese, iron, organic compounds, and hardness.
Replaceable filter cartridges for fine particle removal as pre-treatment or polishing filtration in water treatment systems.
Moving bed biofilm reactor carriers providing surface area for biofilm growth in biological wastewater treatment processes.
Intake strainers and screens that prevent debris and large particles from entering water treatment systems.
Pressure vessels containing multiple layers of filter media for progressive removal of suspended solids and turbidity from water.
Automated systems for dissolving and dosing polyelectrolyte polymers used in flocculation and sludge dewatering processes.
