The I2 Air Fluid Protocol;

The Eco-friendly method for the

elimination of bio-fouling in heat exchangers.

The Problem

Heat exchangers are the heart of any cooling system found in industry. Unfortunately, the efficiency of any exchanger can be compromised when geo-thermal wells or cooling towers become contaminated by bacteria of many kinds.

Bacteria adhere to the walls of the exchanger and form a gelatinous coating known as bio-film. Bio-film causes a reduction in heat transfer through;

Occluded space which increases temperature and pressure through decreased flow within the geothermal or cooling tower side of the heat exchanger.

Thermal insulating matter on the plates impedes heat transfer.

Pitting corrosion on plate surfaces reduces plate heat transfer coefficient.

This increases temperature within the coolant water to the chiller.

Additionally, bio-film and planktonic bacteria can move downstream to diffusion wells where occlusion occurs on screens and and in cooling towers where bacterial contamination occurs.

The AnswerThe APF Cleaning Protocol and I2 Air Infusor

The APF protocol is used to clean the interior surfaces of the heat exchanger of existing bio-film.It is a once a month procedure that requires approx. one hour per month labor time and no disassembly of the exchanger.

It consists of the following:

First, voiding the exchanger of any standing water within the exchanger through the introduction of air using the APF manifold.

Second, introducing the I2 AFI cleaning solution.

Third, provide continuous agitation.

Fourth, liquefy bio-film.

Fifth, remove cleaning solutions.

Finally, start of normal water flow.

The cell wall is exposed continually

to new low dose iodine within the air

bubbles.

Iodine is drawn into the cell and key

amino acids in the respiratory chain are

broken down.

The bacteria is destroyed.

The I2 infused air molecule eliminates free floating bacteria and bacteria resident in existing

biolms.

Iodine converts to Eco-friendly iodide

and moves downstream.

The patented I2 Air Fluid Infusor Cartridge

produces I2 infused bubbles that

•are dosed for accurate elution.

•are unaffected by water temperature, turbidity, mineral content or pH.

•converts to Eco-Friendly iodide after contact with bacteria.

•will not effect most materials.

•will have the same effect on microbes as much higher concentrations.

•are negatively charged.

Throughout the month, the plate walls are continually bathe

in low dose I2 bubbles which keep bio-films from forming in a

various ways.

Turbulent bubbles lift and dislodge biofilm.

Iodine liquefies biofilm.

Bubbles prevent planktonic bacteria from

adhering to plate surface.

The continual profusion of I2 infused bubbles keeps the

plates clean providing optimal heat transfer. The bubbles

continue on to the diffusion well screens and cooling towers

where bio-film is eliminated at those sites.

The results!

“Hi Mike,

We have been running one 300 GPM supply well.  We have left all 3 diffusion wells open.  Each diffusion well has acapacity of 300 GPM.  In order to determine if all 3 diffusion wells are working properly, we turned two off at a timeso that we tested each diffusion well by itself to ensure that it was taking 300 GPM.  All 3 took the 300 GPM of waterwithout increases in incoming or outgoing pressure at the heat exchanger.  I took that to mean that all 3 diffusionwells are working properly.”
