FIELD: chemistry.
SUBSTANCE: composite material is made of two layers. The first layer in the direction of movement of the cleaned liquid is a mixture containing activated carbon sorbent, agglomerates of polyacrylonitrile fibres with the size of 4-60 mm and polyolefin fibres with microparticles of activated carbon sorbent with the size of less than 50 microns deposited on them. The second layer, which prevents the removal of microparticles from the first layer, is made of fluffed polyacrylonitrile fibre.
EFFECT: providing comprehensive water treatment and its uniform softening throughout the work life.
