FIELD: process engineering.
SUBSTANCE: invention relates to water treatment and can be used in whatever field. Initial water is filtered through sorbent containing graphene and/or carbon nanotubes and membrane including cylindrical or conical through 0.0050.3 mcm-dia pores. Proposed device comprises sorbent containing graphene and/or carbon nanotubes and membrane including cylindrical or conical through 0.0050.3 mcm-dia pores. Filtration element membrane is a track membrane. Membrane cylindrical pores are composed by carbon nanotubes. Invention allows to up efficiency and reliability of water treatment and to down costs.
EFFECT: conserved useful mineral elements, higher biological activity.
