FIELD: textile, cotton.
SUBSTANCE: this invention refers to the materials used as carriers of the active bio mass for the water procession, mainly the procession of industrial and domestic waste waters. Bio mass carrier material is made as a nonwoven fabric of the bound with each other by the needle puncturing and/or by the thermally chemisorption, bicomponent and polypropylene synthetic fibres with the linear density from 0.9 to 6.8 dtex. A nonwoven fabric is a three-layer structure, two external layer whereof contains polypropylene or the mixture of bicomponent and polypropylene fibres. The internal layer contains chemisorption fibres. Chemisorption fibres are unreclaimable waste of the initial procession and combing. Additionally, the ration of the surface density of the layers is 1:1:1.
EFFECT: invention improves the active characteristics of the materials in respect of the sorption of different polluting components contained in the waste waters.
