EN This study analysed the influence of surfactants used in the paper industry for cleaning paper machines on polymer-wood composites which can be used in wastewater treatment technology. NALCO 8683 and NALBRITE 2623 surfactants as well as specially prepared composites – thermoplastic and crushed wood samples were used for the research. The mechanical properties of wood-polymer composites (WPC) treated with surfactants were tested under the conditions of static bending and stretching. During the research, it was found that the influence of surfactants on the wood-polymer composites is determined by the residence time of the samples in the solution and the amount of filler used. The test results confirm that wood-polymer composite-based fittings exhibit higher bending and tensile strength compared to those consisting of pure polypropylene. On the basis of the obtained results, it can be concluded that wood-polymer composites can be successfully used as materials for the production of elements used in the moving bed bioreactor technology.
