COMPOSITE MAGNETOSORBENT FOR REMOVING OIL, PETROLEUM PRODUCTS AND OILS FROM WATER SURFACE Russian patent published in 2021 - IPC B01J20/24 B01J20/28 B01J20/02 C02F1/28 E02B15/04 C09K3/32 

FIELD: wastewater treatment.

SUBSTANCE: invention relates to the field of industrial wastewater treatment. A composite magnetsorbent for removing oil, petroleum products and oils from the water surface is proposed, which is a porous matrix based on the husk of cellulose-containing crop waste with a pore size of 0.5 - 1.3 mm, characterized by the fact that it additionally contains non-polluted steel gas cleaning dust with a particle size of 5-10 mcm distributed in the husk both on the outer surface of the matrix and in its pores, while finely ground sunflower husk is, wt. %: 35-50, unpolluted gas cleaning steel dust 25-40 and binder paraffin 10-40.

EFFECT: production of a magnetsorbent having high activity in a magnetic field, high operational characteristics, which is able to quickly and effectively remove oil and petroleum product spills from the water surface when using a magnetic device.
