METHOD OF HIGH-CONTAMINATION FLUID CLEANING AND DEVICE TO THIS END Russian patent published in 2012 - IPC C02F9/12 

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of reused and intake waters, effluents, process fluids, etc, and may be used in metal working and metallurgical plants. Proposed plant comprises mixing tank made up of, at least, three communicated sections. Said sections are equipped with reagent, coagulant and aqueous magnetic fluid feed dispensers. Said tank is communicated with flocculator tank with flow magnetic separator inlet. Proposed plant comprises also vessel for magnetic fluid, cleaned water vessel and extracted product collection vessel. Note here that fluid feed pump is communicated with coarse filter communicated in its turn with mixing tank. Magnetic separator is connected with extracted product collection vessel and that for water suspension of flocculated magnetic slime. Self-cleaning filter is connected with cleaned water tank and extracted product collection vessel. Note also that mixing tank and flocculator tank are furnished with electric mixers.

EFFECT: higher quality of cleaning, power savings.
