I2 Vapor Infusion
Biofouling on heat exchanger surfaces costs industry millions each year on chlorine and other biocidal chemicals, all of which can be harmful to the environment when discharged as water effluent. There is an effective, economical, and environmentally friendly alternative: I2 Vapor Infusion technology.
I2 Vapor Infusion–the injection of iodine-infused vapor bubbles into the cooling water system–is a patented technology which has the potential to substantially reduce biofouling within heat exchangers. HTRI is the exclusive provider of this technology for heat exchanger and cooling tower applications, either directly or through an authorized distributor.
Studies conducted at various universities and with the United States Navy have demonstrated extremely positive results across multiple applications, such as
- significant decrease in the need for heat exchanger cleanings
- dramatic reduction in biological activity
- negligible residual iodine levels in treated water, which are still effective as a biocide
- low operating and maintenance costs
- no capital cost
- environmentally friendly process
Michael Radicone of I2 Air Fluid Innovation, Inc. presented a paper at the 2015 International Conference on Heat Exchanger Fouling and Cleaning in Dublin, Ireland. In-Situ Shipboard Heat Exchanger Maintenance Using Innovative I2 Bubble Infusion Technology details how the I2 Vapor Infusion system was used to reduce the rate of biofouling maintenance within treated heat exchangers.
Scotian Halibut solves biofouling problem with I2 Vapor Infusion
Scotian Halibut Ltd. is an aquaculture farm that controls the temperature of its fish tank water with plate heat exchangers. The company’s current practice has been to reduce biofouling by using hypochlorination twice weekly and backflushing weekly. The I2 Vapor Infusion process was started as an alternative solution. Since switching to the I2 Vapor Infusion process nearly three months ago, no cleaning has been necessary. This has resulted in substantial savings in maintenance costs and exchanger operating costs for this commercial halibut hatchery in Nova Scotia, Canada.
