METHOD OF TREATMENT OF SLUDGE-LIGNIN Russian patent published in 2019 - IPC C02F11/12 C02F1/48 C02F1/34 C02F103/28

Abstract RU 2681617 C1

FIELD: technological processes.

SUBSTANCE: invention can be used in the pulp and paper, chemical and hydrolysis industries for the treatment of sludge-lignin. For the implementation of the method the bond structure of the solid phase of the sediment with water is subjected to action of rotating magnetic field inside the tube made of a non-magnetic material into which ferromagnetic particles are introduced. Magnetostriction of particles is achieved, due to which cavitation is obtained in the water component of the sediment. Sludge lignin is then dehydrated. Duration of the process is 3–15 s.

EFFECT: proposed method for treating sludge effectively, quickly and easily separates the aqueous and solid parts of sludge-lignin without the use of chemicals, without preheating and at low cost of electricity.
