Procedure and system of elimination of organic micropollutants in waste water by means of an enzymatic reactor of ceramic membrane. The invention relates to a process and system for eliminating organic micropollutants present in secondary effluents of wwtp or industrial effluents by ligninolytic enzymes, of the peroxidase or laccase type, in enzymatic membrane reactors (rem), ultrafiltration or nanofiltration ceramic. The water to be treated, after a filtration pre-treatment to minimize the concentration of colloids, is introduced into the reactor, where the enzyme is found: peroxidase or laccase, in free form. The output of the reactor is pumped to the ceramic membrane, separating into two streams. The retentate stream, which contains the enzyme, is recirculated to the reactor. The permeate stream, which is the rem effluent, is free of micropollutants and can be discharged into the aquatic environment.

La invención se refiere a un procedimiento y sistema de eliminación de microcontaminantes orgánicos presentes en efluentes secundarios de EDAR o efluentes industriales por enzimas ligninolíticas, del tipo peroxidasa o lacasa, en reactores enzimáticos de membrana (REM) cerámica de ultrafiltración o nanofiltración. El agua a tratar, tras un pretratamiento de filtración para minimizar la concentración de coloides, se introduce en el reactor, donde se encuentra la enzima: peroxidasa o lacasa, en forma libre. La salida del reactor se bombea a la membrana cerámica, separándose en dos corrientes. La corriente de retenido, que contiene la enzima, se recircula al reactor. La corriente de permeado, que constituye el efluente del REM, está libre de microcontaminantes y puede descargarse al ambiente acuático.
