Processing Technologies Overview

Mercury-containing waste presents a significant environmental hazard and requires specialized processing and neutralization technologies. KS Group LLC provides enterprises and organizations with services for processing and disposal of mercury-containing waste.

Main Types of Mercury-Containing Waste

• Fluorescent mercury lamps (up to 100 million units fail annually)
• Thermometers and other mercury-containing medical devices
• Mercury-containing instruments from school, educational, and research laboratories
• Galvanic cells
• Mercury-containing electrical equipment

Main Directions of Mercury Waste Disposal

• Reagent demercurization — treatment with solutions of ferric chloride, potassium permanganate, iodine-based preparations, sodium sulfide, and others
• Vacuum distillation — waste distillation with cryogenic condensation of mercury vapors to obtain metallic mercury
• Thermal demercurization — thermal processing of waste to produce stuppa (crude mercury)
• Counter-flow purging method — producing mercury concentrate through counter-current gas flow

The vacuum distillation technology is implemented on the URL-2M installation, which produces metallic mercury with a purity of at least 95%. The process includes loading waste into a chamber, heating under vacuum, cryocondensation of mercury vapors, and unloading demercurized waste.
