Biología y Filtración, S.L.
About
Since 1986, Biología y Filtración, S.L. (Bio-Fil) has designed and manufactured plastic biofilm carrier media and engineered biological wastewater treatment systems from its headquarters in Santa Eulàlia de Ronçana, Barcelona, Spain, with distribution across more than 30 countries. The company's flagship BIOFILL® product line includes Type A and Type B media for trickling filters—irregular-surface plastic elements that promote biofilm development for organic matter removal—and the C-series (C, C-2, C-3) designed for moving bed biofilm reactor (MBBR) applications, cooling tower fill, and anaerobic processes. Beyond individual media sales, Bio-Fil delivers complete treatment systems: trickling filter installations simulating natural river-flow filtration, MBBR moving bed systems using C-series carriers, and the proprietary AEMBBR-MBR hybrid that combines moving bed biofilm and membrane bioreactor technology to produce high-quality effluent suitable for water reuse. The company also produces BACTERIA® biological additives—blends of specialized microorganisms combined with powdered activated carbon that adsorb toxic compounds during treatment upsets, serving as a biological shock absorber. Bio-Fil's engineering team develops customized projects for water treatment plants across heavy industry (chemical, petrochemical, mining, pharmaceutical, textile), food processing (dairy, slaughterhouses, beverages), agriculture and aquaculture, and municipal wastewater, with notable clients including Colgate, Revlon, and Kao Corporation.
