ABU is able to capture a wide range of harmful substances with 80% to 99.9% efficiency depending on the input concentration and the physical-chemical properties of the substances.
Presence of solid impurities in the gas flow does not affect ABUs functional characteristics. Meanwhile other «dry» air purifying methods such as the use ion exchange filters, units with gas-discharge cells, coal or zeolites is inefficient as the resinous and suspended substances stick to the working surface.
Low operating costs due to minimal use of consumables (between 0.1 to 1.0 m3/day of water, 30-60 kg/year of biogenic additives, and 30-40 m3/h of compressed air).
ABUs are environmentally friendly, since they do not create any secondary contaminants. For example, thermal and catalyst-assisted combustion release NOx, CO and other partial oxidation by-products. Coal-based methods create contaminated condesate after superheated steam regeneration. Ozonation creates exces ozone, and chemisorption creates a saline solution on top of releasing drops of chemical regents into the atmosphere.
The units are both explosion proof and flameproof. No chemical reagents, acids or alkali are used.
ABU operation can significantly reduce the risk of occupational diseases for employees involved in hazardous production.
The units are easy to operate and do not require a permanent operator. Our specialist will provide all the necessary information and instructions during ABU installation process.
ABU maintenance is minimal and is limited to easy to do pump repairs.
Monitoring of the ventilating emission purification efficiency is carried out periodically, by visually observing the state of irrigation and «boiling» of the nozzle. The absorption solution is analyzed for chemical oxygen consumption once a month. If the absorbent regeneration efficiency needs to be improved, available agricultural fertilizers containing nitrogen and phosphorus are added to the solution.
More than 100 ABUs are operated by 42 companies across various industries in Russia, Belarus, Ukraine and Kyrgyzstan with a lifetime of up to 25 years.
Since the beginning of its operation in 1989, there has not been a single complaint regarding any of the ABUs. Our system does not have any moving or wearing parts except for a conventional water pump. Unit service life is at least 15 years.
