Methods, apparatus, and systems are provided for detecting and removing microplastics from wastewater effluent. Both, automatic/remote and manual monitoring and sampling components are included to detect the presence of microplastics. The automatic monitoring and sampling component includes a TSS sensor and associated apparatus calibrated to account for non-plastic solids present in the wastewater and, thereby, more accurately determine the presence of microplastics. Efficient separation and removal of microplastics from wastewater effluent is performed by a specialized capture net apparatus having multiple sized mesh components and optional diffuser devices which perform size exclusion filtration of microplastics from the water. In an exemplary embodiment, the methods generally include diverting treated wastewater effluent from a wastewater treatment facility's main line into a wastewater sampling mechanism via an intake pipe, and then into a solids monitoring and separation mechanism which includes the specialized capture net apparatus.

The present invention provides a photocatalyst particle comprising titanium dioxide particles, a zeolite particle, and a carbon layer. The titanium dioxide particles are adsorbed on a part of an external surface of the zeolite particle. The carbon layer coats a part of an external surface of the zeolite particle other than the part of the external surface of the zeolite particle on which the titanium dioxide particles are adsorbed. The carbon layer is in contact with a part of surfaces of the titanium dioxide particles. At least a part of the other part of the surfaces of the titanium dioxide particles is not coated with the carbon layer and are exposed on a surface of the photocatalyst particle. The present invention provides a photocatalyst particle used even in an alkaline aqueous solution.

The present invention relates to a method for degrading and inactivating at least one xenobiotic, the at least one xenobiotic being present in an aqueous medium. The method comprises the steps of (a) grafting at least one enzyme onto a solid support, (b) incubating the solid support with the at least one enzyme into the aqueous medium and (c) measuring the evolution of the concentration of the at least one xenobiotic. The method is remarkable in that the at least one enzyme is New-Dehli metallo-β-lactamase 1, a laccase extracted from Pleurotus ostreatus and/or a β-lactamase extracted from Pseudomonas aeruginosa and in that the solid support is a moving bed carrier.
