FIELD: water treatment.
SUBSTANCE: invention relates to purification of water from suspended colloidal particles, microplastics, nitrates and pathogens from any natural sources, as well as to afterpurification of water from a water supply network and purification of waste water. Filtration of contaminated water is carried out through two layers of natural adsorbents. Adsorbents used are chitosan with particle size ranging from 212 to 425 mcm and sand with particle size of 1-1.5 mm. Chitosan is placed in the upper layer, sand – in the lower one. Components are taken in the following ratio, wt.%: chitosan – 7.5, sand – 92.5 (bottom layer).
EFFECT: high degree of purification of water from suspended, colloidal particles, microplastics, nitrates and pathogenic bacteria.
