System for treatment of polluted effluents

A system for treatment of a polluted effluent, said system comprising:

• a. an outer chamber configured to treat an effluent/catalyst mixture comprising the polluted effluent in mixture with a purification slurry comprising particles of one or more catalysts and/or organoclays, or a mixture thereof, wherein the treatment of the effluent/catalyst mixture is carried out by a contact between the particles of one or more catalysts and/or organoclays or the mixture thereof and the polluted effluent to mineralize or degrade pollutants in the polluted effluent, said outer chamber comprising:
• (i) a stirrer comprising an engine, configured to mix the polluted effluent and the purification slurry to prevent said particles from sinking without causing a turbulence;
• (ii) a membrane located at the top of the outer chamber through which a treated effluent passes, while preventing said particles of one or more catalysts and/or organoclays from exiting the outer chamber together with the treated effluent;
• (iii) a membrane cleaning system configured to remove and collect said particles of one or more catalysts and/or organoclays accumulated on the membrane, and re-introducing said particles of one or more catalysts and/or organoclays back to the bottom of the outer chamber, said membrane cleaning system comprises:
• (1) a suction configured to create a vacuum that sucks the particles of one or more catalysts and/or organoclays that accumulate on the membrane, and remove said particles of one or more catalysts and/or organoclays accumulated on the membrane by inversion of a flow direction of the effluent/catalyst mixture;
• (2) an engine configured to rotate said suction across said membrane;
• and
• (3) a collector configured to collect the removed particles, which is fluidly connected to said suction;
• (iv) at least one inlet located at the bottom of the outer chamber, from which the polluted effluent and/or purification slurry enters the outer chamber;
• and
• (v) an outlet at the top of the outer chamber from which the treated effluent exits the outer chamber;
• and
• b. a computerized control system configured to control a speed of flow of both the effluent and the purification slurry, and monitoring a pollutant(s) level in the treated effluent.
