FIELD: wastewater treatment.
SUBSTANCE: invention relates to a solid-phase demulsifier for the separation of an oil-water emulsion by thermochemical sludging, which includes ash structures of oil and table salt obtained by mixing them in equal mass quantities, heat treatment at 1000°C, and an activating additive: manganese nanoparticles, in an amount of 10% of the mass of the resulting ash structure.
EFFECT: increase in the efficiency of the separation process of oil-water emulsions, an increase in the quality of petroleum feedstocks.
